BANDA ACEH, Indonesia - Soldiers, police and volunteers fanned out across an earthquake-damaged region of western Indonesia on Wednesday, scouring the debris of fallen homes and landslides for possible victims of a temblor that killed at least 22 people and injured hundreds.
The magnitude-6.1 quake struck Tuesday afternoon at a depth of just 10 kilometers (6 miles) and was centered on the far western tip of Sumatra island in Aceh province.
Twelve people were killed and 70 others were injured by a landslide or collapsing buildings in Bener Meriah district, said Sutopo Purwo Nugroho of the National Disaster Mitigation Agency. He added Wednesday that the number of houses and buildings damaged in the district is still being counted.
In neighboring Central Aceh district, 10 people were killed, 140 were injured and about 1,500 houses and buildings were damaged, Nugroho said. The quake also triggered landslides and caused hundreds of people to be evacuated to 10 temporary shelters.
Rescuers and other assistance teams have arrived in Bener Meriah, while the air force have dispatched a helicopter and a CN-235 aircraft to the region, Nugroho said.
"We are now concentrating on searching for people who may be trapped under the rubble," said Rusli M. Saleh, the deputy district chief of Bener Meriah.
He said at least 25 of the injured in his district were hospitalized in intensive care.
As the quake hit, villagers in the area ran out of their homes in panic and screamed for help.
"I see many houses were damaged and their roofs fell onto some people," Bensu Elianita, a 22-year-old resident of Bukit Sama village in Central Aceh district, said shortly after the quake hit. "Many people were injured, but it is difficult to evacuate them due to traffic jams."
The quake also caused concern among officials attending a meeting of the Asia Pacific Economic Cooperation forum in Medan, the capital of neighboring North Sumatra province. They were escorted from the second-floor meeting room by security officers.
Indonesia is prone to seismic upheaval due to its location on the Pacific Ring of Fire, an arc of volcanoes and fault lines encircling the Pacific Ocean.
In 2004, a magnitude-9.1 earthquake off Aceh triggered a tsunami that killed 230,000 people in 14 countries.
