Qa'dah 26, 1431, Nov 03, 2010, SPA - Indonesia's most dangerous volcano sent searing gas clouds down its scorched flanks Wednesday, while in the country's other disaster zone, tsunami survivors were thinking twice about rebuilding homes along battered coastlines. The twin disasters, which unfolded simultaneously just over a week ago, have claimed nearly 470 lives and sent tens of thousands fleeing to crowded emergency shelters. They were settling in for the long haul Wednesday, with relief operations expected to take weeks, possibly months. No casualties were reported in Mount Merapi's latest blast, which spewed hot ash and fiery rocks three miles (five kilometers) down the mountain's largely evacuated slopes at 8:11 a.m, the Associated Press reported.
