How many times has the Krakatoa volcano erupted?
Thornton mentions that Krakatoa was known as “The Fire Mountain” during Java’s Sailendra dynasty, with records of seven eruptive events between the 9th and 16th centuries. These have been tentatively dated as having occurred in 850, 950, 1050, 1150, 1320, and 1530.
Is the Krakatoa still active?
Krakatau, a small island group in the Sunda Strait between the islands of Sumatra and Java is one of the world’s most famous volcanoes. It is a mostly submerged caldera with 3 outer islands belonging to the rim and a new cone, Anak Krakatau, that has been forming a new island since 1927 and remains highly active.
What caused the eruption of Krakatoa 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.

Did anyone live on Krakatoa?
Krakatoa was apparently uninhabited, and few people died outright from the eruptions. However, the volcano’s collapse triggered a series of tsunamis, or seismic sea waves, recorded as far away as South America and Hawaii.
Why is Krakatoa so powerful?
Originally Verbeek thought that Krakatoa was so fierce because sea water flooded into the volcano, reacting with molten lava; the build-up of pressure from the resulting steam would have led to an enormous blast. The best way of predicting a blast is to record seismic activity within a volcano.
