Major magnitude-7.5 earthquake strikes off Indonesia. More Here;

A major magnitude-7.5 earthquake has struck off the Indonesian island of Sulawesi, prompting a tsunami alert that was quickly lifted by authorities.

It came hours after a milder quake hit the same area, killing one person and injuring at least 10, and officials expect further damage.

The warning was lifted within the hour, but officials asked people in affected area to remain on the alert as a number of moderate aftershocks hit the area.

“We advise people to remain in safe area, stay away from damaged buildings,” Sutopo Purwo Nugroho, spokesman for the National Disaster Mitigation Agency, said in a televised interview.

The US Geological Survey put the magnitude of the second quake at a strong 7.5, after first saying it was 7.7.

“The [second] quake was felt very strongly, we expects more damage and more victims,” Nugroho said.

A series of earthquakes in July and August killed nearly 500 people on the holiday island of Lombok, hundreds of kilometres southwest of Sulawesi.

Indonesia sits on the Pacific Ring of Fire and is regularly hit by earthquakes.
