A major, 7.7-magnitude earthquake struck in Myanmar on Friday, according to the United States Geological Survey. At a depth of about six miles, the quake was relatively shallow, which made it likely to cause violent shaking.

The powerful earthquake, which had its epicenter in central Myanmar about 13 miles from Mandalay, Myanmar’s second-largest city, struck around 12:50 p.m. local time, the New York Times reported. It was followed by several tremors, including a 6.4 magnitude aftershock which occurred just 11 minutes later.
