The Indonesian island of Lombok is still recovering from a massive earthquake earlier in August, but two more powerful quakes shook the island in the span of 12 hours on Sunday, according to The Jakarta Globe.
A magnitude 6.3 earthquake rattled the island on Sunday morning, two weeks after hundreds of people were killed in the region by powerful tremors.
Eleven hours later, an even stronger quake struck the northeastern portion of Lombok with a magnitude of 6.9, according to the United States Geological Survey, followed by several strong aftershocks.
The latest tremor caused widespread power outages int he Sembalun subdistrict, northeast of Mount Rinjani, according to the Associated Press.
Officials said at least 13 people died due to collapsed buildings or from heart attacks.
Another 24 people were injured after the powerful quake struck in West Nusa Tenggara.
The National Disaster Mitigation Agency (BNPB) delivered a press conference on Monday which said hundreds of homes were destroyed in the magnitude-6.9 earthquake but also warned officials were still responding to the area.
