Meureudu: The death toll from a strong 6.5-magnitude earthquake that struck Indonesia`s Aceh province on Wednesday has nearly doubled to 97, a military chief said.
"So far 97 people have been killed and the number keeps growing," Aceh military chief Tatang Sulaiman told AFP.
The shallow 6.5-magnitude quake struck Pidie Jaya district at dawn, as some in the predominantly Muslim region prepared for morning prayers.
Mosques and shops were flattened in the small town of Meureudu, where the force of the quake sent people fleeing from their homes. No tsunami alert was issued.
The head of the local disaster agency, Puteh Manaf, said the sole hospital in the district had been overwhelmed by the number of injured.
Rescue operations were under way to find those believed trapped beneath the rubble, with heavy machinery being used to shift the debris.
Khairul Nova, an official at the Aceh search and rescue agency, said: "Dozens are missing but we don`t have accurate data on the total yet."
A witness said local residents were wandering the streets, unable to return to their damaged homes and fearing aftershocks.
Images from the scene showed homes levelled, mosque spires toppled and cars crushed under rubble.
The local hospital was struggling to cope, with the injured being treated on the ground outside the front of the building.
Patients were also being sent to a neighbouring district with greater facilities, said deputy district chief Said Mulyadi.
He said at least seven children were among the dead, and many more had suffered broken bones and other injuries.
"There are many shophouses have caved in, and many (people) are alive but trapped," he said.
Seismologists said the earthquake was felt across much of Aceh province, which was devastated by the 2004 Indian Ocean tsunami. At least five aftershocks followed the quake, said Eridawati, local head of the Meteorology, Climatology and Geophysics Agency.
The US Geological Survey upgraded the magnitude to 6.5 from an initial reading of 6.4 and issued a yellow alert for expected fatalities and damage.
Indonesia experiences frequent seismic and volcanic activity due to its position on the Pacific "Ring of Fire", where tectonic plates collide.
Aceh lies on the northern tip of Sumatra island, which is particularly prone to quakes.
In June, a 6.5-magnitude quake struck off the west of Sumatra, damaging scores of buildings and injuring eight people.
A huge undersea earthquake in the Indian Ocean in 2004 triggered a tsunami that engulfed parts of Aceh.
The tsunami killed more than 170,000 people in Indonesia and tens of thousands more in other countries around the Indian Ocean.
