JAKARTA, Indonesia — The popular Indonesian resort island of Lombok, already under a weeklong state of emergency, was struck once again 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 Mitigation Agency said.

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.

The quake occurred in the early evening. Minutes later, a magnitude-5.6 aftershock jolted the region again. It was the first of a wave of about a dozen aftershocks. Thousands fled from their homes to gather in emergency shelters in open spaces, the disaster agency said.

At the international airports on Lombok and Bali, buildings sustained minor damage, Reuters reported, but operations were not disrupted, officials said.

The law and home affairs minister of Singapore, K. Shanmugam, who was in Mataram, the capital of Lombock Island, when the quake struck, said on Facebook that his 10th-floor hotel room had shaken violently and the walls had cracked.

Najmul Akhyar, district chief of North Lombok, initially told Metro TV that at least three people had been killed, according to The Associated Press. Akhyar said, however, that because of an electrical blackout, he did not know whether there were other casualties.

Later, the National Disaster Mitigation Agency reported that the death toll had risen to 37, then to 82.

Sutopo Purwo Nugroho, a spokesman for Indonesia’s National Disaster Management Board, said in a statement that the earthquake was also felt in Sumbawa Island, to the east of Lombok.

Dwikorita Karnawati, head of Indonesia’s national Meteorology, Climatology and Geophysics Agency, said in a televised statement that there were about 12 aftershocks or “smaller earthquakes.”

The U.S. Geological Survey confirmed the 7.0 quake in a post on Twitter.

The earthquake occurred in the same area that a 6.4-magnitude earthquake struck in the early hours of July 29, killing 17 people and injuring more than 160.
