What is the tectonic setting of Krakatau?
Tectonic Setting Krakatau is directly above the subduction zone where the Eurasian Plate and Indo-Australian Plate meet creating a strato-volcano chain. The plate boundaries make a sharp change of direction, possibility resulting in an unusually weak crust in the region.
Where is Mount Krakatoa on a world map?
Krakatoa (/ˌkrɑːkəˈtoʊə, ˌkræk-/), also transcribed Krakatau (/-ˈtaʊ/; Indonesian: Krakatau), is a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung….

Where did Krakatoa erupt?
One of the most powerful volcanic eruptions in recorded history occurs on Krakatoa (also called Krakatau), a small, uninhabited volcanic island east of Sumatra and west of Java, on August 27, 1883.
What kind of volcano is Mount Krakatoa?
stratovolcano
Mount Krakatoa is an example of a stratovolcano, a tall, conical volcano with multiple strata of solidified lava, tephra, as well as volcanic ash. These type of volcanoes typically have steep sides and usually erupt frequently & violently. Most of the popular eruptions have been made by stratovolcanoes.
What type of plate boundary is Krakatau on?
Plate Tectonics: The plates involved in Krakatau are the Eurasian plate and the Indonesian-Australian plate. At this convergent plate boundary, the Indonesian-Australian plate is sub-ducting underneath the Eurasian plate.
Where is the Krakatoa volcano?
Krakatoa Island (Krakatau in Indonesian) is a part of Indonesia and lies close to the Java Sea. It is located in between the Islands of Java and Sumatra. Before the eruption, the volcano stood 790 m above sea level. From 1927 till today, in its place now lies the Child of Krakatoa Island as a new volcano has emerged since the eruption of 1883.
How many tectonic boundaries are there in Indonesia?
The movement forms three types of tectonic boundaries which affect Indonesia which are convergent plates which move into each other, divergent plates which move apart and transform plates which slide past each other horizontally.
What type of plate boundary is between Sumatra and the Indo-Australian Plate?
Furthermore, between Sumatra and the Indo-Australian Plate, a mid-ocean ridge has formed, which is due to the convection currents which rise in the mantle. When the Indo-Australian plate reaches a depth larger than 100km, the water it contains lowers the fusion point of the surrounding rocks, creating magma.
