Hijjah 12, 1431H, Nov 18, 2010, SPA -- The number of people killed by a series of eruptions at Indonesia's most volatile volcano in recent weeks has risen to 275. The National Disaster Management Agency said Thursday that the toll climbed after more than a dozen victims succumbed to their injuries - mostly severe burns. Mount Merapi began unleashing torrents of hot gas, rock and other debris late last month after years of dormancy. The most significant blast came Nov. 5, the deadliest day at the mountain in decades. The disaster agency said most of the 275 people were killed by searing gas clouds. Others died during panicked evacuations or from respiratory problems and other illnesses linked to the mountain, according to a report of the Associated Press.
