On 6 February 2023, at 04:17 TRT (01:17 UTC), a M_w 7.8 earthquake struck southern and central Turkey and northern and western Syria. The epicenter was 37 km (23 mi) west–northwest of Gaziantep. The earthquake had a maximum Mercalli intensity of XII (Extreme) around the epicenter and in Antakya. It was followed by a M_w 7.7 earthquake at 13:24. This earthquake was centered 95 km (59 mi) north-northeast from the first. There was widespread damage and tens of thousands of fatalities.

The M_w 7.8 earthquake is the largest in Turkey since the 1939 Erzincan earthquake of the same magnitude, and jointly the second-largest in the country, after larger estimates for the 1668 North Anatolia earthquake. It is also one of the strongest earthquakes ever recorded in the Levant. It was felt as far as Egypt and the Black Sea coast of Turkey. There were more than 30,000 aftershocks in the three months that followed. The seismic sequence was the result of shallow strike-slip faulting along segments of the Dead Sea Transform, East Anatolian and Sürgü–Çardak faults.

There was widespread damage in an area of about 350,000 km² (140,000 sq mi), about the size of Germany. An estimated 14 million people, or 16 percent of Turkey's population, were affected. Development experts from the United Nations estimated that about 1.5 million people were left homeless.

The confirmed death toll in Turkey was 53,537; estimates of the number of dead in Syria were between 5,951 and 8,476. It is the deadliest earthquake in what is now present-day Turkey since the 526 Antioch earthquake and the deadliest natural disaster in its modern history. It is also the deadliest in present-day Syria since the 1822 Aleppo earthquake; the deadliest worldwide since the 2010 Haiti earthquake; and the fifth-deadliest of the 21st century. Damages were estimated at US$148.8 billion in Turkey, or nine-percent of the country's GDP, and US$14.8 billion in Syria.

Damaged roads, winter storms, and disruption to communications hampered the Disaster and Emergency Management Presidency's rescue and relief effort, which included a 60,000-strong search-and-rescue force, 5,000 health workers and 30,000 volunteers. Following Turkey's call for international help, more than 141,000 people from 94 countries joined the rescue effort.

Tectonic setting

Geology

Map of the Anatolian sub-plate, showing the location of the East Anatolian Fault

Central southern Turkey and northwestern Syria are affected by the interaction between three tectonic plates; the African plate, Arabian plate and Anatolian sub-plate. The boundary between the African and Arabian plates is represented by the Dead Sea Transform (DST)—a major zone of left-lateral strike-slip fault—it accommodates the relative northward movement of Arabia with respect to Africa. The northern end of the DST truncates at the East Anatolian Fault (EAF), another major left-lateral strike-slip fault zone that accommodates the overall westward movement of the Anatolian plate as it is extruded in that direction by the northward movement of the Arabian plate. The DST and EAF meet at the Marash triple junction. The EAF continues west of the triple junction, forming the boundary between the African and Anatolian plates, linking into the Cyprus arc to the west via the Latakia Ridge.

The 700 km-long (430 mi) EAF is subdivided into seven segments, from the northeast; the Karlıova, Ilıca, Palu, Pütürge, Erkenek, Pazarcık and Amanos segments. The Amanos segment is also considered part of the DST by some geologists, or a transitional structure between the EAF and DST by others. A northern strand to the EAF has also been recognized, including the Sürgü, Çardak, Savrun, Çokak, Toprakkale, Yumurtalık, Karataş, Yakapınar and Düziçi–İskenderun segments. The estimated slip rate on the main strand of the EAF system decreases south-westwards from 10 mm (0.39 in) per year on the Karlıova segment down to 2.9 mm (0.11 in) per year on the Amanos segment. On the northern strand, a slip rate of 2.5 mm (0.098 in) per year was estimated on the Çardak segment. The Sürgü-Çardak Fault is an east–west striking 160 km (99 mi) long fault that runs north of the EAF. It branches away from the EAF west of Çelikhan and extends westwards to Göksun. Comprising two segments; the Sürgü Fault runs 70 km (43 mi) between Çelikhan and Nurhak; the Çardak Fault runs 90 km (56 mi) between Nurhak and Göksun. Seismicity on the fault is low—the only associated earthquake was a M 6.8 event in 1544.

The northern part of the DST is subdivided into several segments, although there is some disagreement between scientists as to which faults should be assigned to the DST and which to the EAF, at the northernmost end of the structure. Following the 2013 "Active Fault Map of Turkey", seven DST segments are recognized in Turkey and neighbouring parts of Syria; the Afrin, Sermada, Armanaz, Hacıpaşa, Yesemek, Sakçagöz and Narlı segments.

Seismicity

The EAF has produced large or damaging earthquakes in the past few hundred years along various segments, including the 1789 (M 7.2, Palu), 1795 (M 7.0, Pazarcık), 1866 (M 7.2 Karlıova), 1872 (M 7.2, Amanos), 1874 (M 7.1, Palu), 1875 (M 6.7, Palu), 1893 (M 7.1, Erkenek), 1971 (M6.6, Karlıova) and 2020 (M 6.8, Pütürge) events. Other large historical earthquakes have been tentatively assigned to segments of the EAF, such as the 1114 and 1513 Marash earthquakes, both thought to have ruptured the Pazarcık segment.

The Palu and Pütürge segments in the east display a recurrence interval of about 150 years for M 6.8–7.0 earthquakes. The Pazarcık and Amanos segments in the west have recurrence intervals of 237–772 years and 414–917 years, respectively, for M 7.0–7.4 earthquakes. A research paper published by Earth and Planetary Science Letters in 2002 studied stress accumulation and increased seismic hazard along the East Anatolian Fault. The study concluded two sections of the fault with a considerably high potential for future earthquakes. One of these sections was in Elazığ and Bingöl, located between the rupture zones of the 1874 and 1971 earthquakes. The seismic gap ruptured during a M_w  6.1 earthquake in 2010. The 2020 M_w  6.8 earthquake ruptured to the southwest between the 1893/1905 and 1874 earthquakes. Another seismic gap was located in Kahramanmaraş—this 103 km (64 mi) long section—according to the study, believed to last rupture in 1513 has the potential to produce magnitude 7.3 earthquakes.

Large earthquakes on the northern part of the DST include events in 115, 526, 587, 1138, 1170 and 1822, which resulted in several tens of thousands to several hundreds of thousands of fatalities.

Earthquake sequence

The first and largest earthquake in the sequence struck at 01:17 UTC. The United States Geological Survey (USGS) and Global Centroid Moment Tensor (GCMT) measured it at M_ww 7.8 and M_w 7.8, respectively. GEOSCOPE reported M_w 8.0 and Kandilli Observatory (KOERI) reported M_w 7.7 and M_L 7.4. It had an epicenter 34 km (21 mi) west of Gaziantep in Gaziantep Province, which is near the border with Syria. The earthquake hypocenter was at a depth of 10.0 km (6 mi) according to USGS and 5 km (3 mi) according to KOERI. The shock had a focal mechanism corresponding to strike-slip faulting.

It is one of the strongest ever recorded in Turkey, equivalent in magnitude to the 1939 Erzincan earthquake (M_w 7.8). These earthquakes are surpassed only by the larger estimates for the 1668 North Anatolia earthquake. Globally it was the strongest recorded since August 2021. Both earthquakes are the largest and only observed to occur on land within a short span of time.

M_w 7.7 earthquake at 10:24 UTC

Seismogram

At 10:24 UTC, an earthquake measuring M_ww 7.5 according to USGS, M_w 7.6 according to KOERI, or M_w 7.7 according to Geoscope and the GCMT, struck with an epicenter near Ekinözü, 95 km northeast of the M7.8 event. It had a depth of 7.4 km (5 mi) according to the USGS, 5 km (3 mi) by KOERI, and 13 km (8 mi) by Geoscope. The shock was also the result of strike-slip faulting; it had an epicenter north of the previous large earthquake.

A reevaluation of the earthquakes using long-period coda moment magnitude obtained M_w  7.95 ± 0.013 and M_w  7.86 ± 0.012, respectively. These earthquakes were some of the largest Turkish earthquakes in over 2,000 years.

Aftershocks

For a more comprehensive list, see List of aftershocks of the 2023 Turkey–Syria earthquake.

Over 570 aftershocks were recorded within 24 hours of the M_w 7.8 earthquake and over 30,000 recorded by May 2023. An aftershock measuring M_ww 6.7 occurred about 11 minutes after the mainshock. There were 25 aftershocks M_w 4.0 or greater recorded within six hours of the main tremor, according to the USGS. More than 12 hours later, the USGS had reported at least 54 aftershocks of 4.3 or greater magnitude, while the Turkish Disaster and Emergency Management Presidency (AFAD) recorded at least 120 total aftershocks. A M_ww 6.3 aftershock struck near Uzunbağ in Hatay Province on 20 February; the earthquake was the result of oblique-normal faulting. The M_w  7.8 earthquake had aftershocks distributed along ~350 km (220 mi) of the EAF.

The M_w 7.7 earthquake triggered its own aftershock sequence, including two mb 6.0 aftershocks. Aftershocks of the second earthquake continued through at least 9 February. Thousands of aftershocks associated with this earthquake were distributed along an east–west trend corresponding to the Çardak Fault for about 170 km (110 mi).

A source model for the M_ww 7.8 earthquake produced by the USGS from observed seismic waves, taking into account preliminary rupture mapping from satellite data, uses three fault segments with individual lengths, widths, strikes and dips of >40 km (25 mi) × 30 km (19 mi), 028°/85° (Segment 1), >175 km (109 mi) × 30 km (19 mi), 060°/85° (Segment 2) and >160 km (99 mi) × 20 km (12 mi), 025°/75° (Segment 3). The mainshock produced a maximum slip of 11.2 m (37 ft) along Segment 2, beneath Sakarya in Kahramanmaraş Province, northeast of the junction where it meets Segment 1. Another zone of large slip estimated at 4.96 m (16.3 ft) occurred further northeast along Segment 2, northwest of Adıyaman.

The USGS source model for the M_w 7.7 earthquake which struck nine hours later has three large fault segments with individual lengths, widths, strikes and dips of >70 km (43 mi) × >20 km (12 mi), 276°/80° (Segment 1), >40 km (25 mi) × >20 km (12 mi), 250°/80° (Segment 2) and ~80 km (50 mi) × >20 km (12 mi), 060°/80° (Segment 3). Maximum displacement occurred on Segment 1 at 11.4 m (37 ft).

Three segments of the EAF were involved in the M_w  7.8 rupture; the Amanos, Pazarcık and Erkenek segments. The earthquake ruptured ~370 km (230 mi) of the EAF, producing a maximum slip of up to ~12 m (39 ft) along the Pazarcık segment. The northern end of the rupture was about 20–30 km (12–19 mi) south of the M_w  6.8 earthquake that struck in 2020. This section of the EAF, the Pütürge segment, between both earthquakes, may represent a seismic gap. The southern segment of the EAF rupture was at its termination, near Antakya. Slip peaked at 12 m (39 ft) from the surface to 7 km (4.3 mi) depth during the M_w  7.7 earthquake; slip was 11 m (36 ft) at the surface. Slip along the fault was compact—mostly confined to within the Çardak Fault; it was also shallower—attenuating from 8–12 km (5.0–7.5 mi). Slip during the M_w  7.8 event extended to 18 km (11 mi) and 12 km (7.5 mi) for the M_w  7.7 event. The M_w  6.4 aftershock that struck Antakya on 20 February had a rupture area of 25 km (16 mi) × 25 km (16 mi) and produced a peak slip of 0.93 m (3 ft 1 in) at 8.3 km (5.2 mi) depth.

Preliminary analysis of the effects of stress changes caused by the M7.8 earthquake on the Çardak–Sürgü Fault, based on the USGS fault model, indicated up to 3 bars of added stress near the epicenter of the M7.7 shock, sufficient to trigger rupture on that zone, assuming that it was already close to failure. Stress on the Hatay Fault, source of the 20 February M_w  6.4 aftershock, increased by 1 bar following the 6 February earthquakes.

Preliminary analysis based on seismology and observations of surface rupture suggest rupture along a branch of the DST before transitioning onto the EAF where most of the faulting was observed. The initial rupture at the site of the epicenter of the M7.8 shock on the Narlı Fault, the northernmost section of the DST. The fault ruptured unilaterally northwards until it reached the Pazarcık segment of the East Anatolian Fault. Ruptures then continued bilaterally to the northeast and southwest along this segment. This subevent on the Narlı Fault corresponded to a M_w  7.0 earthquake which ruptured for 20 seconds. It had a focal mechanism corresponding to oblique-normal faulting. A preliminary analysis of near-field (within 1 km (0.62 mi) of the fault rupture) seismic records indicates that the initial rupture speed transitioned to supershear after propagating about 19.5 km (12.1 mi) away from the epicenter along the Narlı Fault before it reached the EAF. Back projection suggests the total rupture length was ~560 km (350 mi).

The rupture continued northeast onto the Ekernek segment and to the southwest onto the Amanos segment. The northeastern rupture ceased 55 seconds after initiation while the southwestern rupture ceased near Antakya about 80 seconds later. A M_w 6.8 aftershock occurring 11 minutes later and west of the first M>7 epicenter may have ruptured along the Sakçagöz Fault, the next segment of the DST to the south. Rupture along the EAF during the event occurred at subshear velocity (maximum 3.2 km (2.0 mi) per second). An analysis of near-field seismic data revealed transient supershear rupture episodes throughout the EAF rupture. Supershear rupture occurred along the northernmost section of the Narlı Fault where it meets the EAF. The rupture transitioned onto the EAF and propagated northeast at supershear velocity until its termination near Malatya. Rupture towards the southwest was mostly subshear, but at the southern termination in Hatay, where the fault has multiple branches and kinks, supershear was likely observed. Supershear rupture at the southern termination contributed to the intense ground motion in Antakya.

The second M>7 earthquake initiated on a separate fault known as the Çardak–Sürgü Fault Zone, part of the northern strand of the East Anatolian Fault. The rupture propagated bilaterally along the Çardak segment, continuing eastwards onto the Sürgü segment before continuing eastwards to Malatya along the northeast–southwest trending Doğanşehir Fault Zone. Rupture also propagated towards the southwest along the Çardak segment. The total rupture length was estimated at 160 km (99 mi). The westward-propagating rupture occurred at supershear velocity (maximum 4.8 km (3.0 mi) per second) while the eastward-propagating rupture occurred at subshear velocity (maximum 2.8 km (1.7 mi) per second). The rupture lasted about 35 seconds.

The M_w  6.4 aftershock on 20 February occurred along the Hatay Fault. The focal mechanism indicated normal faulting along a northeast–southwest striking fault.

Surface rupture

Interferogram of the M_w  7.8 mainshock

The extent of surface ruptures associated with the M7.8 and M7.7 earthquakes have been mapped using a mixture of satellite imagery and ground observations. Pixel matching on images captured by Sentinel-1 before and after the earthquakes showed sharp discontinuities in displacement, revealing two separate zones of surface rupture. The longer of the pair, produced by the first earthquake, measured 320 km (200 mi) while the second earthquake produced 150 km (93 mi) of surface rupture. These observations were backed up with direct imaging of the ruptures using other satellite data, such as from the DigitalGlobe's WorldView-1, 2 & 3 and GeoEye-1, and by field work. Remote sensing using satellite imagery indicated 30 km (19 mi) of surface rupture with large normal faulting component.

The zone of surface rupture extended from north of Antakya, Hatay Province towards Pazarcık, Kahramanmaraş Province and Gölbaşı, Adıyaman Province. Surface ruptures continued north of these cities. Surface rupture occurred in the Amik Valley. The westernmost part of Hatay Airport was damaged by surface ruptures but cracks in the runway were attributed to ground deformation. A major canal was damaged and lead to flooding in parts of the Amik Valley which was formerly Lake Amik. Field observations indicate a maximum displacement of 7.3 m (24 ft) on the surface. Geologists traced a 15 km (9.3 mi) surface rupture trending south from Pazarcık with an offset of 2.5 m (8 ft 2 in). From Golbasi to Nurdağı ground displacements were up to 5 m (16 ft). The surface rupture observed during the M7.8 earthquake was unusually large, comparable to that during the 1906 San Francisco earthquake along the San Andreas Fault.

Large surface offsets of 6–8 m (20–26 ft) were observed along the Sürgü-Çardak Fault. Along a road west of Gözpınar, the rupture displaced the road left-laterally for 8.6 m (28 ft). The largest maximum surface offset was 10.0–12.6 m (32.8–41.3 ft); one of the largest surface offsets ever observed from an earthquake.

Ground motion

Ground acceleration values recorded in some areas near the fault rupture were in excess of 1 g. Three USGS seismic installations, two at Antakya and one at Hassa, recorded large ground accelerations and velocities. The town of Hassa recorded 0.9082 g in ground acceleration (pga) and 215.34 cm/s (84.78 in/s) in ground velocity. The station data corresponded to a Modified Mercalli intensity of X (Extreme). A peak ground acceleration of 1.62 g was recorded by a station at Fevzipaşa. The peak ground acceleration generally exceeded 0.5 g in a large area around the epicenter, near Adiyaman and a large part of Hatay. High pga values of 2 g were recorded in Hatay. The maximum recorded pga was 2.212 g at a station in Pazarcık Belediyesi Parkı, Pazarcık; a government health facility nearby had limited damage but the surrounding town was devastated. The maximum recorded pga during the M_w  7.7 earthquake was 0.59 g at Göksun.

According to Kandilli Observatory, the maximum Mercalli intensity (MMI) of the mainshock was estimated to have reached MMI XI–XII (Extreme) in Antakya and near the epicenter. MMI XI (Extreme) or higher was observed along the fault rupture from the epicenter to Antakya. The MMI also reached IX–X (Violent–Extreme) in Kahramanmaraş and İskenderun, VIII–IX (Severe–Violent) in Malatya and Adıyaman, VII–VIII (Very strong–Severe) in Gaziantep, Kilis, Idlib and Aleppo, and VI–VII (Strong–Very strong) in Adana and Şanlıurfa. The maximum MMI of the second earthquake was X (Extreme).

Geological effects

Liquefaction was identified via satellite and remote sensing along the southern portion of the M_w 7.8 rupture on the East Anatolian Fault from Antakya to Gölbaşı. Liquefaction and lateral spreading were observed at and near coastal areas, fluvial valleys and drained lake or swamp areas, covered by Holocene sediments. These effects were widespread in the Amik Valley and Orontes River plain, north of Antakya, Hatay Province. Limited observations were made in high-elevation areas due to snow cover and lack of satellite observations. Liquefaction was also observed in Samandağ. At Lake Gölbaşı, Adıyaman Province, lateral spreading occurred along the northern, eastern and southern coast. Parts of the lakeshore were also submerged. Gölbaşı was also damaged by liquefaction and lateral spreading.

Subsidence at Lake Gölbaşı from lateral spreading lead to floods along the shore

Subsidence due to lateral spreading caused extensive damage in İskenderun. Liquefaction produced sand ejecta that buried Atatürk Boulevard in Çay District. Regular flooding in the city was observed after the earthquakes. Earlier flooding may be attributed to liquefaction while subsequent occurrences may be due to damage to the coast and water infrastructure. The sea inundated parts of the city by as much as 200 m (660 ft). Large areas of the coast and sections of piers were flooded due to lateral spreading. Large waves from bad weather and a tsunami may have contributed to the effects observed at İskenderun.

Both earthquakes caused shaking levels (≥0.12 g) sufficient for landslide-triggering across a 90,000 km² (35,000 sq mi) area. About 3,673 earthquake-triggered landslides were identified using satellite imagery, aerial photos, and one field survey of the area. Landslides mainly occurred in the northern region of the affected area. Rockslides were the most commonly observed; there were also many bedrock rotational landslides, translational slides and lateral spreads. Surface ruptures propagating through hillsides also triggered landslides. These landslides blocked roads and river channels, destroyed or seriously damaged buildings and caused many deaths.

One of the largest landslides occurred near Tepehan village, Hatay Province; a translational slide which detached a block 1.3 km² (0.50 sq mi). This landslide occurred in a region comprising marl and clay-rich limestone. It produced a 20 m (66 ft) vertical displacement along its scarp. ITV News reported the landslide scarp was up to 1,000 ft (300 m) long and "wider than a football pitch" in some areas.

Tsunami

Despite an epicenter 90 km (56 mi) inland, a tsunami was recorded in the Mediterranean Sea. It was the first recorded tsunami in the eastern Mediterranean Sea region since the one produced by the 1953 M_L  6.2 earthquake in Cyprus. The largest wave measured 40 cm (16 in) along the Mediterranean coast of Turkey. Although no underwater surveys results have been made available to identify the sources of these tsunamis, they were likely produced by landsliding at Iskenderun Port and liquefaction on the coastal flatlands of Antakya.

Small tsunami waves were recorded off the coast of Famagusta, Cyprus, without damage. The tsunami measured 0.17 m (6.7 in), and tsunami waves were recorded at 0.12 m (4.7 in) at İskenderun and 0.13 m (5.1 in) at Erdemli. Tsunami warnings were issued for the southern Turkish coast, southern and eastern Italian coasts and the whole eastern Mediterranean Sea area, but later withdrawn.

Effects on other faults

The earthquake rupture terminated near Suvatlı in the Amik Valley, where some 10.5 km (6.5 mi) to its east is the Hacıpaşa Fault, a Dead Sea Transform segment. The rupture was arrested by a stepover that connects the East Anatolian Fault with the Hacıpaşa Fault. Though it did not rupture, the Coulomb stress increased on the Hacıpaşa Fault. With a combination of the increases stress, 600–900 years without major earthquakes, and an annual slip rate of 5 mm (0.20 in), it is a potential source of magnitude 7.0 or greater earthquakes. The accumulated slip along this segment is estimated at 3–9 m (9.8–29.5 ft). An earthquake "domino effect" remains plausible along the Dead Sea Transform beginning with the Hacıpaşa Fault, as observed along the North Anatolian Fault, where successive earthquakes have migrated westwards along the fault since 1939.

There were 53,537 deaths and 107,213 injured across 11 of the 17 affected provinces of Turkey. About 140 people remain missing; 118 in Hatay Province. At least 15.73 million people and 4 million buildings were affected. More than 2 million residents in the affected provinces were evacuated to nearby provinces including Mersin, Antalya, Mardin, Niğde and Konya. At least 518,009 houses and over 345,000 apartments were destroyed. More than 20 percent of Turkey's agriculture production was affected. The United Nations said crops, livestock, fisheries, aquaculture and rural infrastructure were heavily damaged. At least 516 university buildings were affected, of which 106 were heavily damaged.

By 23 February 2023, the Ministry of Environment, Urbanization and Climate Change conducted damage inspections for 1.25 million buildings; revealing 164,000 buildings were either destroyed or severely damaged. Another inspection carried out in March revealed that 1,411,304 housing units sustained light to moderate damage. Over 150,000 commercial infrastructure were at least moderately damaged. The International Organization for Migration estimated over 2.7 million people were made homeless. A damage assessment by the Turkish government revealed at least 61,722 buildings had to be demolished including 11,900 in Gaziantep Province, 10,900 in Hatay Province, 10,800 in Kahramanmaraş Province and 36,046 in Malatya Province. Broad fissures appeared on roads. During recovery efforts, body parts were often found in the rubble.

The collapse of the luxury Rönesans Rezidans apartment trapped an estimated 800 people, killing at least 269 and leaving 46 missing as presumed dead. In May 2023, an investigation by The New York Times found that inadequate design and safety lapses may have contributed to its collapse. An engineer revealed to the newspaper; "the building violated the basic tenets of engineering," after inspecting its blueprints. Contractors of the building said they adhered to building regulations but those were not enough against the earthquake.

The 13-storey apartment block consists of three closely spaced buildings linked externally, but not structurally; when the collapse occurred, all three buildings separated. The basement, two-storey parking space was considered the "strongest part" of the complex as it had more concrete walls than other parts of the structure. The building's exterior walls and those that separated units and rooms consisted of heavy masonry which may have prevented the structure from swaying and possibly held the building mostly intact despite toppling. The building was considered a soft story structure as the ground floor had fewer masonry walls which meant it was at greater risk of damage from seismic ground motion. Among other factors were that the core concrete columns which housed the elevator systems were situated along the north side which left the south side vulnerable without adequate support. Another reason was that beams emerging from either side of the building were misaligned and did not connect to each other. These features may have contributed to the building overturning onto its south side.

Turkey was placed on a "level four" alert to request international aid. More than 53,000 Turkish search and rescue personnel were dispatched to the affected provinces. Seventy countries also assisted in these operations. In the first two days, more than 8,000 people were rescued and 380,000 people were relocated to shelters or hotels. An "air aid corridor" was established by the Turkish Armed Forces to mobilize search and rescue teams. Poor weather conditions and damaged roads hampered rescue and relief missions. By 19 February, most rescue efforts had concluded except in Hatay and Kahramanmaraş provinces.

Syria made an appeal to UN member states, the International Committee of the Red Cross, and other humanitarian organizations for international aid. President Bashar al-Assad ordered all teams of the civil defense, firefighting, health and public construction groups to be mobilized in the affected governates. He also added that medical services, food and shelter were urgently needed. The Ministry of Internal Trade and Consumer Protection was ordered by President al-Assad to supply food and organize teams to distribute them. Technical teams were also on site to evaluate building conditions and evacuate residents in at-risk structures. The Ministry of Water Resources was tasked with rapidly assessing damage to dams, reservoirs and water stations, and ensuring people have access to water. Some hotels including in Latakia and Damascus offered to accommodate to survivors free of charge and ensure basic necessities. Refugees and expatriates also opened their homes as shelters for people. Sports facilities, events venues, university dormitories and halls were also opened to take in people. The Syria Trust for Development announced the establishment of shelters across many governorates. Volunteer groups inspected buildings for damage and distributed food items, blankets and first aid essentials. Many hospitals were overwhelmed by the large number of casualties and prior to the earthquakes, were already experiencing supply shortages.

The World Bank said it would provide US$1.78 billion in aid for Turkey to support the relief and recovery process. "We are providing immediate assistance and preparing a rapid assessment of the urgent and massive needs on the ground," said World Bank President David Malpass.

National mourning

President Erdoğan declared seven days of national mourning in Turkey on Twitter. Seven days of national mourning was observed in Northern Cyprus, and one day in Bangladesh and Kosovo. Albania's prime minister, Edi Rama, said 13 February would be a day of national mourning. On 13 February, all overseas diplomatic missions of North Macedonia lowered the Macedonian flags to half-mast.

Criticism by the Syrian government and opposition

Investigative reports revealed that Syrian government had deliberately obstructed aid to all of Syria's opposition-held areas, including the Idlib region, which was the worst-struck area in the earthquake. Syrian government officials and state-run media blamed United States and European Union sanctions against the country for the lack of humanitarian aid and hampering rescue. On 10 February, Syrian president Bashar al-Assad accused Western countries of having "no regard for the human condition." The US Treasury said its sanctions "contain robust exemptions for humanitarian efforts" in the first place, and that after the earthquake it issued a blanket authorization for relief efforts. The United Nations has also been criticized for its policy of focusing aid shipments solely to the regime, at the expense of Syrian lives in opposition-held territories.

Idlib region, under the control of Syrian Salvation Government (SSG), was one of the hardest-hit territories. Assad regime's policy of besieging North-West Syria; which blockades the supply of food, medicines and other humanitarian supplies, has further deteriorated the crisis in Idlib. Abu Mohammad al-Julani, commander of the SSG-aligned Tahrir al-Sham rebel militia, criticized aid agencies of neglecting the situation in Idlib and called on the international community to be more proactive in reconstruction and relief efforts, adding that the "United Nations needs to understand that it's required to help in a crisis". Upon traveling to the Bab al-Hawa Border Crossing bordering the rebel-held territories, UNOCHA Under-Secretary Martin Griffith stated on 12 February that "We have so far failed the people in north-west Syria". As of 13 February, Ankara and the Turkish-backed Free Syrian Army were accused of blocking aid convoys sent by the Autonomous Administration of North and East Syria from entering the north-west region.

The United Nations criticized Russia's attempts to block delivery of aid through checkpoints to rebel-held territories. Secretary General António Guterres urged the Security Council to immediately permit aid flows into Northwestern Syria. United States appealed for the immediate opening of all closed checkpoints to send in relief efforts to all parts of Syria; calling for an emergency UN Security Council meeting to increase humanitarian assistance through Bab al-Hawa and open up more border crossings for the entry of UN aid. Stéphane Dujarric, a United Nations spokesperson, said on 14 February, "some aid is getting into the north-west, pointing to 58 trucks that arrived with aid through the Bab Al-Hawa crossing." However, the organization does not possess heavy equipment or search and rescue teams. He stressed that the "international community as a whole needs to step up to get that aid where it is needed."

Raed al-Saleh, chief of Syrian Civil Defence, strongly rebuked the UN for its negligence and delay in responding to the rescue efforts:

"Let me be clear: The White Helmets received no support from the United Nations during the most critical moments of the rescue operations.. The UN's failure to respond quickly to this catastrophe is shameful. When I asked the UN why help had failed to arrive in time, the answer I received was bureaucracy. In the face of one of the deadliest catastrophes to strike the world in years, it seems the UN's hands were tied by red tape."

Health concerns

Due to below-freezing temperatures in the affected areas in both Turkey and Syria, the mayor of Hatay, Lütfü Savaş, warned about the hypothermia risk. In Adiyaman Province, some residents trapped under rubble died from hypothermia.

Concerns arose regarding the possible spread of infection in areas where sanitation facilities were damaged or unfunctional. Due to water shortage experienced in both countries, many survivors could not shower. International health organizations said the shortage of clean water would be a public health risk. The World Health Organization said water shortage "increases the risk of waterborne diseases and outbreaks of communicable diseases."

On 18 February, Turkey's Health Minister Fahrettin Koca said there was an increase in intestinal and upper respiratory infection cases but "numbers did not pose a serious threat to public health." At a stadium serving as shelter in Kahramanmaraş, a clinic managed by 15 to 30 medics attended up to 10,000 patients in the day. The clinic provided tetanus shots and sanitary items to residents. Many people at the stadium were unable to shower and the six toilets were unable to accommodate to the large number of people. In Antakya, residents said more portable toilets were needed.

Health authorities in Turkey had to ensure earthquake survivors were free of disease. The World Health Organization collaborated with local authorities to monitor the rates of waterborne diseases, seasonal influenza and COVID-19 among the affected.

Commemorations

On the first anniversary of the earthquake on 6 February 2024, the Turkish government organized a series of programs to mark the disaster, with schools closed in the affected regions. In Antakya, a moment of silence was held at 04:17, when the earthquake struck, and carnations were scattered into the Orontes River. A silent march was held in Adiyaman while President Erdoğan is expected to visit Kahramanmaraş. Protests were also held in Antakya criticizing health minister Fahrettin Koca and mayor Lütfü Savaş, with demonstrators chanting "Can anyone hear me?", a reminder of cries for rescue following the earthquake and "We won't forget, we won't forgive." In Malatya Province, the governor banned events that were not officially sanctioned until 9 February.
