evidence: On Feb. 6, 2023, a magnitude-7.8 earthquake struck at 4:17 a.m. local time near Pazarcık City in south-central Türkiye. This earthquake was followed by a second earthquake of magnitude 7.5 at 1:24 p.m. with the epicenter in Elbistan City. Both events are associated with the East Anatolian fault system. The two earthquakes were felt as far away as Syria, Cyprus, Greece, Jordan, Lebanon, Iraq, Georgia, Armenia, Egypt, and Israel. As of Feb. 23, 2023, the death toll from the Türkiye earthquakes has reached 43,566 in Türkiye alone. The number of collapsed buildings and heavily damaged buildings that must be demolished has reached 156,000. The number of buildings sustaining medium and light damage is around 43,000. The number of housing units within those collapsed and heavily damaged buildings is around 507,000, indicating the size of emergency housing needed for earthquake victims. We expect this number to rise. [...] The magnitude-7.8 event of Feb. 6, 2023 is Türkiye’s most powerful earthquake recorded since 1939, when the magnitude-7.8 Erzincan earthquake, struck northeastern Turkey along the right-lateral strike-slip North Anatolian fault system. The 1939 event ruptured a 360 kilometer long fault with a horizontal offset of up to 7 meters. Estimates suggest about 33,000 lives were lost.
