On Saturday, Japan's Mount Ontake volcano erupted without warning, surprising several hundred nearby hikers. Plumes of volcanic gas and ash overtook the fleeing hikers and buried nearby lodges and outbuildings. Though most of the people on Mount Ontake that day were able to escape. 40 suffered significant injuries and at least 36 bodies have been found so far, according to Japanese authorities. More than 24 bodies remain at the summit, and recovery crews have been unable to return, wary of more activity from Ontake as tremors continue to shake the region.
