A powerful aftershock from a deadly earthquake rocked Colombia on Sunday, and religious services were held in the open in towns where churches were damaged.

A quake with a preliminary magnitude of 5.7 shook much of Colombia, including Bogota, at 5:41 a.m. Sunday, the government’s Geology and Mining Institute said.

It was centered 75 miles northeast of Bogota, in the same area as Thursday’s 6.5 magnitude quake, which killed eight people.

Six people were hurt in Sunday’s quake.
