Krakatoa is a volcano in Indonesia that lies at the convergent boundary between the Eurasian and Indo-Australian tectonic plates. It was formed sometime within the past million years, when the two plates collided and the Indo-Australian plate began sliding under the Eurasian plate. The volcano is famous for its major eruption in 1883, which killed 36,000 people and was one of the deadliest eruptions in human history.Know More
This eruption created tsunamis that swept along the coasts of the nearby islands of Sumatra and Java, and the explosion was so loud that it was heard more than 2,000 miles away in Australia.
Prior to the eruption in 1883, the massive Krakatoa volcano was spread out over three islands: Krakatoa, Verlaten and Lang. Perlaten and Lang Islands had been formed by two other volcanoes, Danan and Perbuwatan. However, this eruption was so violent that it destroyed most of all three volcanic cones and much of Krakatoa Island.
In 1927, a new island began to surface in between the three islands, caused by further small eruptions of Krakatoa. The name of this new island is Anak Krakatoa, which means Son of Krakatoa, and this new caldera has experienced quite frequent but fairly minor eruptions since it emerged from the ocean.Learn more about Plate Tectonics
When tectonic plates collide and form a convergent boundary, their interaction can produce earthquakes, volcanic activity, underwater trenches and mountain formations. Any resulting geologic events on the Earth's surface are determined by the type of tectonic plates involved in the collision: oceanic crust, continental crust or a combination of both.Full Answer >
Krakatoa is a volcanic island located in the Sunda Strait between Java and Sumatra in Indonesia. The island measures 3 miles wide by 5 1/2 miles long.Full Answer >
At a transform plate boundary, two tectonic plates pass one another, creating a fracture zone. This motion causes phenomena such as earthquakes.Full Answer >
The most active plate boundary is in the Pacific Ocean basin. Several tectonic plates collide in this area, which is known as the Ring of Fire due to the high number of volcanoes, earthquakes, deep sea trenches and other seismic activities occurring on its rim.Full Answer >
