JAKARTA, Indonesia — The popular Indonesian resort island of Lombok, already under a weeklong state of emergency, was struck once again on Sunday by a powerful earthquake. At least 82 people were killed in the quake, which was also felt on Bali, just to the west, the country’s National Disaster Management Board said.

Television footage showed panicked residents and tourists fleeing to safety on both islands, especially after a warning that the quake and major aftershocks could cause a tsunami.

Most of the people killed in the magnitude-7.0 quake, which was first announced as a magnitude 6.8 and then revised upward, were from the northern and western regions of Lombok.
