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.
The effects of the eruption were felt worldwide. It ejected roughly 10,000,000,000 tonnes (1.1 Ã 10 10 short tons) or 10 km 3 (2.4 cu mi) of magma, and 20,000,000 tonnes (22,000,000 short tons) SO 2, bringing vast quantities of minerals and metals to the surface environment.It injected more particulate into the stratosphere than any eruption since Krakatoa in 1883.Over the following months, the aerosols formed a global layer of sulfuric acid haze. Global temperatures dropped by about 0.5 Â°C (0.9 Â°F) in the years 1991-93, and ozone depletion temporarily increased substantially.t ejected roughly 10,000,000,000 tonnes (1.1 Ã 10 10 short tons) or 10 km 3 (2.4 cu mi) of magma, and 20,000,000 tonnes (22,000,000 short tons) SO 2, bringing vast quantities of minerals and metals to the surface environment.
