A 7.7 magnitude earthquake rattled much of Southeast Asia on Friday, flattening skyscrapers and leaving more than 1,000 people dead from Myanmar to Thailand.

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.

A magnitude 7.7 earthquake in Myanmar caused widespread shaking and likely considerable damage because of a lack of buildings built to withstand temblors
