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 ...
The term "Sunda" has been traced back to ancient times. The name "Sunda" originates from the Sanskrit word "Cuddha," meaning white. During the Pleistocene era, there was a large volcano named Mount Sunda located north of Bandung in West Java. Its eruption covered the surrounding area with white volcanic ash, giving rise to the name "Sunda."
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.
"Sunda" also denotes continental shelves or landmasses. Indonesia itself has two shelves: the Sunda Shelf in the west and the Sahul/Arafuru Shelf in the east. Other terms associated with "Sunda" include the Sunda Island Arc or the arc of Sunda Islands, Sunda Fold or tectonic folding in the Natuna Sea, the Sunda Trench, and Sundaland. [1]
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 ...
Kelimutu lies within the Sunda Arc, a volcanic arc that was formed by the subduction of the Indo-Australian Plate under the Eurasian Plate. [9] This tectonic activity creates numerous volcanoes in and across Indonesia, including Kelimutu. The volcano contains three striking summit crater lakes of varying colors. Tiwu Ata Bupu (Lake of Old ...
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]
A volcanic arc is a chain of volcanic islands or mountains located near the edge of continents that are formed as the result of tectonic plate subduction. Subcategories This category has the following 7 subcategories, out of 7 total.
