Fourteen people are confirmed dead and an unknown number of others are missing after Mount Semeru in Lumajang district in East Java, Indonesia erupted during heavy rains that triggered a collapse of the lava dome at the mountain’s summit, the Associated Press reports . Semeru, an active volcano home to thousands, was ordered evacuated Saturday following the eruption, but many returned to check on their livestock and homes in defiance of authorities’ warnings Semeru probably wasn’t done with its tantrum yet.
