UPDATE: At least four people are dead after a powerful earthquake with a preliminary magnitude of 6.8 shook central Myanmar on Wednesday, knocking glasses off tables and sending people running out of buildings in the country’s largest city. The U.S. Geological Survey said the quake was centered about 25 kilometers (15 miles) west of Chauk, an area west of the ancient capital of Bagan. It was located fairly far below the Earth’s surface at a depth of about 84 kilometers (52 miles), it said. Deep earthquakes generally cause less surface damage.

At least 185 brick pagodas in Bagan were damaged, the Ministry of Religious and Cultural Affairs said in a statement. Bagan, also known as Pagan, has more than 2,200 structures including pagodas and temples constructed from the 10th to the 14th centuries. Many are in disrepair while others have been restored in recent years, aided by the U.N. cultural agency UNESCO. CONTINUE
