The first 7.0-magnitude quake was just six miles (10 kilometers) deep, according to the U.S. Geological Survey. It was followed by another of the same strength but far deeper: 140 miles (230 kilometers).
The quakes struck along Myanmar’s borders with Thailand and Laos, about 70 miles (110 kilometers) from the northern Thai city of Chiang Rai.
Buildings swayed in Bangkok, 500 miles (800 kilometers) south of the epicenter.
The Pacific Tsunami Warning Center says it was located too far inland to create a destructive wave.
