A magnitude 6.5 earthquake struck off the coast of Indonesia around 5 a.m. local time on Wednesday, killing nearly 100 people.
The death toll is expected to rise as rescue and recovery efforts continue, NPR's Anthony Kuhn reports.
The quake was at a relatively shallow depth, just 11 miles under the Earth's surface, Anthony says. Its epicenter was on the coast of Aceh province, the same region where an earthquake triggered a devastating tsunami in 2004.
No tsunami warning has been issued following Wednesday's quake. Aftershocks continue to shake the region.
