Authorities extended a danger zone around a rumbling volcano in western Indonesia on Sunday after it spewed blistering gas farther than expected, sending panicked residents streaming down the sides of the mountain, AP reported. Mount Sinabung's booming explosion just after midnight triggered a panicked evacuation. Men with ash-covered faces streamed down the scorched slopes on motorcycles, followed by truckloads of women and children, many crying. Officials barked out orders on bullhorns as rocks and debris rained from the sky. More than 50 eruptions on Saturday sent lava and searing gas tumbling out of the volcano in North Sumatra province down the southeastern slopes up to five kilometers (three miles) away, said Indonesia's disaster mitigation agency spokesman Sutopo Purwo Nugroho. The volcano was still spitting clouds of gas and lava as high as 4,000 meters (13,000 feet) in several eruptions Sunday, but no casualties were reported. Nugroho said that the danger zone southeast of the volcano was extended from five to seven kilometers (three to four miles) from the crater's smoldering mouth. Soldiers joined the rescue operation in two villages of Jewara and Pintu Besi, about seven kilometers (four miles) from the crater, where homes and farms were caked in gray dust. More than 20,000 people have been evacuated from villages around the crater into several temporary shelters since authorities raised the alert status for Sinabung to the highest level in November.
