GEOLOGY HISTORY OF INDONESIA


Indonesia has a long history of major geological events that have killed hundreds of thousands of its people and caused repercussions across the globe. Super volcano Toba (N. Sumatra) featured the world's largest known explosion and created a lake 100 km long and 30 km wide. The 1815 eruption of Mt. Tambora killed over 100,000 people and caused "the year without summer" as volcanic ash settled over the globe. In 1883 Krakatoa Volcano exploded and was heard as far away as Australia, it generated a tsunami that travelled 22 miles inland killing over 36,000 people and helped cool temperatures around the world for many years. Since 2000, earthquakes, volcanic eruptions and tsunamis have continued to disrupt life in Indonesia, causing the deaths of over 250,000 and the destruction of over 2,000,000 homes and buildings. Situated on a major fault and part of the infamous volcanic zone called the "Ring of Fire", Indonesia was created from violent seismic activity that created most of the 17,000 islands that form the nation today.
