âtašfešân-e Tambora

Fr.: volcan Tambora   

The largest volcanic eruption in recorded history, which mainly occurred on April 10, 1815 in the Indonesian Sumbawa Island. An estimated 150 cubic kilometers of igneous material was ejected, whereby the mountain lost ~ 1400 m in height during the blast (current height ~ 2900 m). The eruption created a 6 km-wide, 1250 m-deep → caldera. The ash put into the atmosphere produced high-latitude clouds which intercepted incoming sunlight. The resulting drop in → insolation caused a dramatic change in climate and weather patterns in the Northern Hemisphere during the following year. The year 1816 is known as the "year without a summer" because there was no warm season over much of the Northern Hemisphere.
