evidence: A 7.8-magnitude earthquake struck Turkey and Syria in the early hours of the morning on February 6 with the large southeastern Turkish city of Gaziantep at its epicenter. This was followed less than 10 hours later by a 7.5-magnitude aftershock slightly to Gaziantep’s north. In addition to its impact on Turkey and Turkish citizens, the twin quakes hit the heart of a border area home to millions of Syrian refugees at a time of great economic and geostrategic uncertainty in Turkey and across the region. [...] A3: Turkey ranks among "the most seismically active countries in the world." The initial 7.8 earthquake on February 6 was the highest magnitude earthquake recorded in Turkey since 1939 and the second highest in its recorded history. But earthquakes are a regular fact of life in many parts of a country that sits on the intersection of two major fault lines. The February 6, 2023, quakes happened along the East Anatolian Fault, though the most recent major earthquake almost a quarter century ago happened along the North Anatolian Fault.
