7.8
"...... WHY WAS IT SO SEVERE?
The East Anatolian Fault is a strike-slip fault.
In those, solid rock plates are pushing up against each other across a vertical fault line, building stress until one finally slips in a horizontal motion, releasing a tremendous amount of strain that can trigger an earthquake.
The San Andreas Fault in California is perhaps the world's most famous strike-slip fault, with scientists warning that a catastrophic quake is long overdue.
The initial rupture for the Turkey-Syria earthquake kicked off at a relatively shallow depth.
"The shaking at the ground surface will have been more severe than for a deeper earthquake of the same magnitude at source," David Rothery, a planetary geoscientist at the Open University in Britain, said. ....."

Explainer: Why was the Turkey-Syria earthquake so bad?
The magnitude 7.8 earthquake that struck Turkey and Syria on Monday is likely to be one of the deadliest this decade, seismologists said, with a more than 100 km (62 miles) rupture between the Anatolian and Arabian plates.
