What did the explosion of Krakatoa cause?
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.
What happened at Krakatoa?
An enormous blast on the afternoon of August 26 destroyed the northern two-thirds of the island; as it plunged into the Sunda Strait, between the Java Sea and Indian Ocean, the gushing mountain generated a series of pyroclastic flows (fast-moving fluid bodies of molten gas, ash and rock) and monstrous tsunamis that …
