What plate boundary is Krakatau on?
convergent plate boundary 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. Magma is rising up all along that boundary, making Indonesia a very active area.
What plates are interacting to form Krakatoa?
Beneath Krakatoa, the denser Australian Plate is being subducted beneath the Eurasian Plate. An infamous eruption in 1883 destroyed the entire island, sending volcanic gas, volcanic ash, and rocks as high as 80 kilometers (50 miles) in the air.
What 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.
Is Krakatoa on a destructive plate boundary?
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. Mainly made up of strato-volcanoes. Explosive volcanism.
How was Anak Krakatoa formed?
Anak Krakatoa formed over years after the explosive eruption of the Krakatoa volcano in 1883, one of the largest and most catastrophic in recorded history. Before 1883, the only confirmed eruption on the Krakatoa island group was a moderate one, some two centuries before, in 1680.

What is Krakatoa made of?
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 caused Krakatoa 1883 eruption?
This eruption was caused by high pressure buildup in the two underlying tectonic plates. The resulting crack allowed for water to enter the volcano and mix into the magma cavity. This along with the extremely heated steam resulted in extremely intense pressure and an almost complete destruction of the island.
Was Krakatoa caused by an earthquake?
After a long period of inactivity (about 200 years), Krakatoa became active again in early 1883. The first indication that something was happening on Krakatoa was when a large earthquake struck the area. Seismic activity became stronger until May 20,1883, when the volcano abruptly came to life.
When was Krakatoa formed?
1883 In 1927, a fourth island, Anak Krakatau, or "Child of Krakatoa", emerged from the caldera formed in 1883. There has been new eruptive activity since the late 20th century, with a large collapse causing a deadly tsunami in December 2018….

What caused Anak Krakatoa to erupt?
Our findings show that, although there was a dramatic, explosive eruption after the collapse of Anak Krakatau, this was triggered by the landslide releasing pressure on the magma system — like a champagne cork popping. ' The results present a challenge for predicting future hazards at volcanic islands.
What caused the eruption of Anak Krakatau?
The major factors that led to the collapse of Anak Krakatau were its location on the north eastern flank of a deep submarine trough (220 m deep), the migration of the volcano itself closer to the edge of the trough and the very weak base of the volcano which was formed of older volcanic deposits.
How do you spell Krakatoa?
a volcano and small island in Indonesia, between Java and Sumatra: violent eruption 1883.
What caused Krakatoa to erupt in 1883?
This eruption was caused by high pressure buildup in the two underlying tectonic plates. The resulting crack allowed for water to enter the volcano and mix into the magma cavity. This along with the extremely heated steam resulted in extremely intense pressure and an almost complete destruction of the island.
How Anak Krakatoa was formed?
Anak Krakatoa formed over years after the explosive eruption of the Krakatoa volcano in 1883, one of the largest and most catastrophic in recorded history. Before 1883, the only confirmed eruption on the Krakatoa island group was a moderate one, some two centuries before, in 1680.
What plates caused the 1883 Krakatoa 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.
How was Anak Krakatau formed?
Anak Krakatoa formed over years after the explosive eruption of the Krakatoa volcano in 1883, one of the largest and most catastrophic in recorded history. Before 1883, the only confirmed eruption on the Krakatoa island group was a moderate one, some two centuries before, in 1680.

Why did Anak Krakatau erupt?
The major factors that led to the collapse of Anak Krakatau were its location on the north eastern flank of a deep submarine trough (220 m deep), the migration of the volcano itself closer to the edge of the trough and the very weak base of the volcano which was formed of older volcanic deposits.
How many volcanoes are in the World 2021?
There are about 1,350 potentially active volcanoes worldwide, aside from the continuous belts of volcanoes on the ocean floor at spreading centers like the Mid-Atlantic Ridge. About 500 of those 1,350 volcanoes have erupted in historical time.
Is Mt St Helens still active?
Mount St. Helens remains the most active volcano in the Cascade Range. Of the volcanoes in the contiguous U.S., it is the most likely to erupt in the future and even in "our lifetimes," according to USGS. However, neither a large avalanche or lateral blast like those in 1980 are likely due to the deep crater.
How was Krakatoa formed?
Krakatoa lies along the convergence of the Indian-Australian and Eurasian tectonic plates, a zone of high volcanic and seismic activity. Sometime within the past million years, the volcano built a cone-shaped mountain composed of flows of volcanic rock alternating with layers of cinder and ash.

What caused Anak Krakatoa to form?
Krakatoa was quiet until December 1927, when a new eruption began on the seafloor along the same line as the previous cones. In early 1928 a rising cone reached sea level, and by 1930 it had become a small island called Anak Krakatau (“Child of Krakatoa”).
