Which tectonic plate interaction caused the Krakatoa volcanic eruption?
This region was caused by the crash of two tectonic plates, the Eurasian plate and the Indo-Australian plate, and thus caused a giant subduction zone (Volcanoes in Indonesia, 2009). Krakatoa Island (Krakatau in Indonesian) is a part of Indonesia and lies close to the Java Sea.
What type of fault is Krakatoa on?
Krakatau is one of a several volcanic islands in the Sunda Straits located above an active north-northeast trending fault zone, an orientation quite distinct from the main island-arc trend.
What continent is Krakatoa in?
The volcanic island known as Krakatoa is located in the Sunda Strait, between the islands of Java and Sumatra. At the time of its famous eruption in 1883, the region was part of the Dutch East Indies; it’s now part of Indonesia.
How Krakatoa was formed?
Krakatau volcano lies in the Sunda strait between the islands of Java and Sumatra. In about 416 A.D., caldera collapse destroyed the volcano and formed a 4-mile (7-km) wide caldera. The islands of Krakatau, Verlaten, and Lang are remnants of this volcano.
Where is Krakatoa located on the tectonic plates?
Lace your climbing boots tight, because this quiz will test whether you can conquer the highest peaks of knowledge. Krakatoa lies along the convergence of the Indian-Australian and Eurasian tectonic plates, a zone of high volcanic and seismic activity.
Is the Indonesian-Australian Plate sub ducting underneath the Eurasian Plate?
At this convergent plate boundary, the Indonesian-Australian plate is sub-ducting underneath the Eurasian plate. Magma is rising up all along that boundary, making Indonesia a very active area.
How big was the eruption of Krakatoa in 1883?
A Depiction of the 1883 Eruption of Krakatoa (Coward and Parker, 1888). The final mega eruption that occurred at Krakatoa was considered to be colossal. On the Volcanic Exclusivity Index it was rated as a number 6, with 7 being the highest rating.
Why is Indonesia at a convergent plate boundary?
At this convergent plate boundary, the Indonesian-Australian plate is sub-ducting underneath the Eurasian plate. Magma is rising up all along that boundary, making Indonesia a very active area. At a convergent boundary, one plate sub-ducts under another. This allows hot magma from deep inside the earth to rise up into the cracks.
