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 islands are part of a volcanic arc, the Sunda Arc, formed by subduction along the Sunda Trench in the Java Sea. In 1930 the population was 3,460,059; [2] today slightly over 15.5 million people live on the islands.
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 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]
The scientific community is abuzz following the first eruption of Mauna Loa—the world’s largest volcano, situated on the Island of Hawaii—since 1984. The eruption occurred just before ...
The islands of Lombok and Sumbawa lie in the central portion of the Sunda Arc. The Sunda Arc is home to some of the world's most dangerous and explosive volcanoes. The eruption of nearby Mount Tambora on Sumbawa is known for the most violent eruption in recorded history on 15 April 1815, with a scale 7 on the VEI. [8]
These eruptions have taken place from the main caldera and fissures along rift zones. They are generally fluid ( VEI -0) Hawaiian eruptions but more violent eruptions have occurred throughout Mauna Loa's eruptive history, with the largest recorded explosive eruptions having taken place in the 19th century.
