Top 10 Largest Volcanic Eruptions

Volcano is defined as “an opening, or rupture, in the earth’s surface, which allows hot magma, fiery hot ash and volcanic gases to escape from the magma chamber below the surface of the earth”. There are several types of volcanic eruption depending upon the behaviour exhibited by the eruptions, but they are broadly classified into three types; magmatic eruptions, phreatomagmatic eruptions and phreatic eruptio. The basic constituents of every volcanic eruption include lava, tephra (ash, lapilli, volcanic bombs and blocks), and various gases.

    Tambora, Indonesia, 1815

    The explosion of Mount Tambora was the biggest ever volcanic eruption recorded by humans. The volcano, which exploded in 1815, is one of the highest peaks in the Indonesian archipelago. The volcanic eruption reached its peak in April 1815, when it exploded so loudly that the bang was heard on Sumatra Island (12,000 miles away from the site), and the ash thrown into the air effectively blocked out sunlight and the solar radiations. The overall death toll from this volcanic eruption was 92,000.

    Krakatoa (Krakatau), Indonesia, 1883

    Krakatoa, a stratovolcano located along a volcanic island arc at the subduction zone of the Indo-Australian seismic plate, blew to its peak on April 26-27 1883 with the force of 13 thousand atomic bombs and was heard thousands of miles away. The volcanic eruption was so intense that it destroyed almost the entire island. More than 36,000 people lost their lives in the 1883 eruption.
