Scientists say the powerful Indonesian M6.9 earthquake that killed nearly 400 people lifted the island by as much as 25 centimeters (10 inches). The National Disaster Mitigation Agency said on Saturday that 387 people died, jumping from the 321 it reported the previous day, as search and rescue teams continued to sift through the rubble and people already buried by relatives are accounted for.
Using satellite images of Lombok from the days following the Aug. 5 quake, scientists from NASA and the California Institute of Technology’s joint rapid imaging project made a ground deformation map and measured changes in the island’s surface.
In the northwest of the island near the epicenter, the rupturing faultline lifted the earth by a quarter of a meter. In other places it dropped by 5-15 centimeters (2-6 inches).
Consequences of the earthquake
Almost 390,000 people, about 10 percent of Lombok’s population, are homeless or displaced after the earthquake, which damaged and destroyed about 68,000 homes.
Disaster agency spokesman Sutopo Purwo Nugroho said three districts in the north of Lombok still haven’t received any assistance. The governor of West Nusa Tenggara province, which includes Lombok, has extended the official emergency period by two weeks to Aug. 25.
“It’s estimated the death toll will continue to grow because there are still victims who are suspected of being buried by landslides and collapsed buildings and there are deaths that have not been recorded,” Nugroho said.
The number of evacuees fluctuates, he said, because not all evacuee points have been counted and some people tend to their gardens and properties during the day and return to the tent camps at night. Some people don’t need to evacuate because their homes aren’t damaged but have come to refugee centers because they feel traumatized.
Nearly a week since the 6.9 quake, Lombok is still reeling but glimmers of normality were returning for some and devout villagers are making plans for temporary replacements of mosques that were flattened.
In Tanjung, one of the worst affected districts in the hard-hit north of the island, a food market opened Saturday and locals bought vegetables and fish. Some shops also opened for business despite being in damaged buildings.
Lombok, a popular and less developed tourist destination than neighboring Bali, was hit by three strong quakes in little over a week and has endured more than 500 aftershocks.
A July 29 quake killed 16 people. An aftershock measuring magnitude 6.2 on Thursday caused panic, more damage and more than two dozen injuries.
Indonesia is prone to earthquakes because of its location on the “Ring of Fire,” an arc of volcanoes and fault lines in the Pacific Basin. In December 2004, a massive magnitude 9.1 earthquake off Sumatra triggered a tsunami that killed 230,000 people in a dozen countries.
