A strong earthquake has rocked Indonesia's Sumatra island, flattening buildings and killing at least 70 people.
The U.S. Geological Survey says the magnitude six-point-three earthquake struck Tuesday, 50 kilometers from West Sumatra's provincial capital, Padang.
An aftershock with a magnitude of six-point-one on the Richter scale was also recorded.
Officials say hospitals and other medical facilities were overwhelmed by hundreds of injured, many suffering broken bones and open wounds.
Some buildings collapsed and others were badly damaged. Many panicked residents of Sumatra refused to return indoors for hours, fearing more aftershocks.
The worst-affected area is Solok, a bustling town near the epicenter. At least 19 people were killed there. Local officials expect that number to rise as bodies are recovered from under debris.
Hundreds are spending the night in schools, mosques, and in tents set up in open fields.
The temblor was felt hundreds of kilometers away in Malaysia and prompted the evacuation of several buildings in Singapore.
No tsunami warning was issued.
Indonesia was the nation worst-hit by an earthquake that triggered the Indian Ocean tsunami in December 2004 that killed an estimated 230-thousand people.
The archipelago of some 17 thousand islands sits on what is called the Pacific Ring of Fire, an arc of volcanos and fault lines along the edge of the Pacific Ocean.
