A pow­er­ful earth­quake rocked Myan­mar and neigh­bor­ing Thai­land on Fri­day, killing at least three peo­ple in Bangkok and bury­ing dozens when a high-rise build­ing un­der con­struc­tion col­lapsed. Footage shared on so­cial me­dia from Myan­mar’s sec­ond-largest city showed wide­spread de­struc­tion, rais­ing fears that many were trapped un­der the rub­ble or killed.

The 7.7 mag­ni­tude quake, with an epi­cen­ter near Man­dalay in Myan­mar, struck at mid­day and was fol­lowed by a strong 6.4 mag­ni­tude af­ter­shock.

The ex­tent of death, in­jury and de­struc­tion — es­pe­cial­ly in Myan­mar, which is em­broiled in a civ­il war and where in­for­ma­tion is tight­ly con­trolled at the best of times — was not yet clear.
