2023-02-06, M7.8, M7.5, Turkey

On the 6th of February 2023 at 01:17:35 (UTC) an M7.8 earthquake occurred in South-Eastern Turkey (see map below). The event effected Turkey, Syria and surrounding areas. The earthquake struck 30 km WNW of Gaziantep, Turkey and 108 km NNW of Aleppo, Syria, both of which are densely populated areas. Several strong aftershocks have also been observed in the region, notably a magnitude M7.5 about 100km north of Gaziantep at 10:24:49 (UTC) the same day. Over five thousand deaths and many injured, largely due to building collapse, have been reported. The M7.8 and M7.5 earthquakes occurred at depths of 18km and 10km respectively. Such large, shallow earthquakes produce significant ground shaking.
