PHOTOS: From Bangkok to Mandalay, scenes of destruction from a deadly quake

A massive earthquake rocked the heart of mainland Southeast Asia on Friday, causing deadly destruction in Myanmar and in the Thai capital.

The magnitude 7.7 quake struck at 12:50 p.m. Myanmar time. Buildings collapsed across a swath of central Myanmar, a country already reeling from four years of civil war since a military coup.

In neighboring Thailand, water tumbled from swimming pools situated on skyscrapers in Bangkok, and a high-rise construction site pancaked, leaving dozens of people trapped inside.
