Big Blast from Indonesia's Semeru Kills at Least 14 People

An unexpectedly large explosive eruption from one of the largest Indonesia volcanoes has ended killing over a dozen people after pyroclastic flows roared down the mountain's slopes. Located on the Indonesia island of Java, Semeru has been erupting for almost 8 years now, but on December 4 the volcano unleashed a blast that reached over 50,000 feet (15 kilometers) when the lava dome at the summit likely collapsed due to heavy rains. Some of the footage from the minutes after the eruption are truly startling as people raced to escape the hot ash flows.
