Volcanic Eruption (Science)

Mount Tambora

On the 10th of April 1815, the biggest volcanic eruption in human history occurred. Mount Tambora is a stratovolcano. The eruption was from the mountain called Mount Tambora on the Indonesian island of Sumbawa.  The blast, Pyroclastic flow and Tsunamis left 100,000s dead. It took six months for all the smaller eruption and the steam clouds. Before the eruption Mount Tambora was 4,300 Metres (14,000 Ft) high, after the eruption it was 2,851 Metres (9,354 Ft). After the eruption it left a caldera spanning 6km across remained. They're most common along the planet's great subduction zones, where a tectonic plate plunges beneath another, generating the rock melt necessary to produce volcanic activity.
