More than 500 dead as 7.8-magnitude earthquake hits southern Turkey

More than 500 people were killed in two countries after one of the strongest earthquakes to hit Turkey in more than 100 years sent tremors across the region, collapsing buildings and sending residents running into the streets, CNN reports.

The 7.8-magnitude quake struck just after 4 a.m. Monday morning local time, 23 kilometers (14.2 miles) east of Nurdagi, Gaziantep province, at a depth of 24.1 kilometers (14.9 miles), the United States Geological Survey (USGS) said. Nurdagi is located along the Turkey-Syria border, and the quake was felt in several countries across the region, including Syria and Lebanon.

In Turkey, at least 284 people were killed and more than 2,300 injured, according to Vice President Fuat Oktay. In neighboring Syria, at least 237 people died and more than 630 were injured, Syrian state news agency SANA reported citing a Ministry of Health official. The deaths were reported in Aleppo, Latakia, Hama and Tartus.

Dozens of people are trapped under rubble, according to the “White Helmets” group, officially known as Syria Civil Defense, a humanitarian organization formed to rescue people injured in conflict. Much of northwestern Syria, which borders Turkey, is controlled by anti-government forces amid a bloody civil war that began in 2011.

The quake struck before daybreak on Monday, when residents were likely asleep and unprepared for the impact. Video from Turkey shared on social media showed dozens of collapsed buildings, while frightened residents huddled on the darkened streets amid the chaos. Rescue workers can be seen conducting search-and-rescue operations by flashlight.

Monday’s quake is believed to be the strongest to hit Turkey since 1939, when an earthquake of the same magnitude killed 30,000 people, according to the USGS. Earthquakes of this magnitude are rare, with fewer than five occurring each year on average, anywhere in the world. Seven quakes with magnitude 7.0 or greater have struck Turkey in the past 25 years – but Monday’s is the most powerful.

Karl Lang, an assistant professor at Georgia Tech University’s School of Earth and Atmospheric Sciences, told CNN the area hit by the quake Monday is prone to seismic activity. “It’s a very large fault zone, but this is a larger earthquake than they’ve experienced any time in recent memory,” Lang said.
