The Sunda Arc is a volcanic arc that produced the volcanoes that form the topographic spine of the islands of Sumatra, Nusa Tenggara, Java, the Sunda Strait, and the Lesser Sunda Islands. The Sunda Arc begins at Sumatra and ends at Flores, and is adjacent to the Banda Arc. [1] The Sunda Arc is formed via the subduction of the Indo-Australian ...
Beginning on 20 May 1883, and ending on 21 October 1883, the volcanic island of Krakatoa, located in the Sunda Strait, had repeated, months long volcanic eruptions. The most destructive of these eruptions occurred on 27 August, when over 70% of the island and its surrounding archipelago were destroyed when it erupted so violently it collapsed ...

In May 1883, after years of intense seismic activity in the Sunda Strait, the massive volcano on the uninhabited island of Krakatoa exploded in a furious eruption. It sent a cloud of ash 50 miles ...
The most notable eruptions of Krakatoa culminated in a series of massive explosions over 26–27 August 1883, which were among the most violent volcanic events in recorded history. With an estimated Volcanic explosivity index (VEI) of 6, [2] the eruption was equivalent to 200 megatons of TNT (840 PJ)—about 13,000 times the nuclear yield of ...
Mount Galunggung is part of the Sunda Arc extending through Sumatra, Java and the Lesser Sunda Islands, which has resulted from the subduction of the Australian Plate beneath the Eurasian Plate. For the first time since 1982 after eruptions finished and conditions seemed normal, on February 12, 2012, the status was upgraded to Alert based on ...
According to the U.S. Geological Survey, there are around 1,350 potentially active volcanoes around the world outside of the continuous range of volcanoes as part of the Mid-Atlantic Ridge. In the ...
The volcano formed the northern ridge of the Bandung Basin. The ancient volcano is the predecessor of today's Tangkuban Perahu, Burangrang, and Bukit Tunggul volcanoes. The Sunda volcano was a stratovolcano and is estimated to have reached up to 3,000–4,000 metres (9,850–13,100 ft) above sea level during the Pleistocene age. [1]
