A 7.7-magnitude earthquake, followed by a second, 6.4-magnitude quake within an hour, hit central Myanmar on Friday, causing tremors across Southeast Asia. Videos showed that the ceiling of Mandalay International Airport had collapsed, leading to cancellation of all flights. The Sagaing and Magway regions, northeastern Shan State, and the cities of Mandalay and Naypyidaw declared states of emergency.
