Qa'dah 19, Oct 27, 2010, SPA -- Planes and helicopters packed with rescue workers and supplies landed for the first time Wednesday on remote Indonesian islands that were pounded by a 10-foot (three-meter) tsunami, sweeping away villages and killing at least 272 people. The first aerial surveys of the region revealed huge swaths of land underwater and the crumbled rubble of homes torn apart by the wave. On Wednesday evening, disaster official Ade Edward nearly doubled the estimated number of casualties to 272 dead with 412 missing, according to a report of the Associated Press. President Susilo Bambang Yudhoyono, meanwhile, cut short a state visit to Vietnam to deal with two major disasters that struck Indonesia in less than 24 hours. The country's most volatile volcano, Mount Merapi, 800 miles (1,300 kilometers) to the east, erupted at dusk Tuesday, sending up searing ash clouds and killing more than two dozen people.
