A preliminary report on the February 6, 2023 earthquakes in Türkiye​

POSTED ON FEBRUARY 24, 2023 BY TEMBLOR
At 4:17 a.m. on Feb. 6, 2023, a magnitude-7.8 earthquake struck near Pazarcık City in south-central Türkiye, followed by a magnitude-7.5 event about 9 hours later. In this report, scientists from Türkiye explain what happened, including the complexity of the rupture itself, ground motion, building codes, and damages.

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.
Figure 1 shows the epicenters of these two earthquakes and the contour for MMI VII, the Modified Mercalli Intensity of shaking that resulted in light-to-medium damage for buildings in Türkiye. This contour (thick yellow line in Figure 1) shows the approximate boundary of regions significantly affected by the earthquakes and encompasses the ruptured segments of the fault and the higher intensities that reached MMI X levels.


Figure 1. This isoseismal map shows the contour (heavy yellow outline) for equally felt shaking intensity of MMI VII — the level of shaking expected to result in negligible damage in well-designed and constructed buildings and slight to moderate damage in well-built ordinary structures, according to the U.S. Geological Survey.Figure 1. This isoseismal map shows the contour (heavy yellow outline) for equally felt shaking intensity of MMI VII — the level of shaking expected to result in negligible damage in well-designed and constructed buildings and slight to moderate damage in well-built ordinary structures, according to the U.S. Geological Survey.


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 earthquakes came as winter storms impacted the region, with freezing temperatures and snowfall. These conditions unfortunately have compounded the challenges faced by the extensive search and rescue operations conducted by local teams, who are supported by international teams.

Sometimes the planet moves on scales beyond even the grasp of scientists:



From a Google search:

"March 13, 2023, at 8:11 a.m. ANKARA (Reuters) - The death toll in Turkey from last month's major earthquakes has risen to 48,448, Interior Minister Suleyman Soylu said on Monday, as authorities rush to set up container cities to house for the longer-term those left homeless by the disaster.2 days ago."
