What happened in the 1883 eruption of Krakatoa?
Heard 3,000 miles away, the explosions threw five cubic miles of earth 50 miles into the air, created 120-foot tsunamis and killed 36,000 people. Krakatoa exhibited its first stirrings in more than 200 years on May 20, 1883. A German warship passing by reported a seven-mile high cloud of ash and dust over Krakatoa.

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 Mount Krakatoa cause a tsunami?
The August 1883 eruption of Krakatoa was one of the deadliest volcanic explosions in modern history. The eruption was so loud it could be heard in Reunion, some 3,000 miles away. As the volcano collapsed into the sea, it generated a tsunami 37m high – tall enough to submerge a six-storey building.
How tall was the Krakatoa tsunami?
42 metres
It generated a tsunami that struck surrounding coastlines at a maximum height of 42 metres and caused at least 36,000 deaths at a time when coastal areas were far less densely populated.
Will Krakatoa ever erupt again?
At some point in the future, Anak Krakatoa will erupt again, generating more tsunamis. Since it is difficult to predict exactly which areas of the Sunda Strait will be affected, it is of paramount importance that residents in coastal villages are well aware of the danger.
What is the deadliest volcanic eruption in history?

How many people did the Krakatoa eruption 1883 kill?
The eruption of Krakatoa, or Krakatau, in August 1883 was one of the most deadly volcanic eruptions of modern history. It is estimated that more than 36,000 people died. Many died as a result of thermal injury from the blasts and many more were victims of the tsunamis that followed the collapse of the volcano into the caldera below sea level.
Why did Krakatoa erupt in 1883?
The 1883 eruption is believed to have been caused by sea water making its way into the magma resivoir under the volcano, likely opened up by any number of earthquakes, or the smaller eruption that occured leading up to the big eruption.
What impact did Krakatoa have on the world?
Krakatoa eruption cooled the world. WHEN the Indonesian volcano Krakatoa erupted in 1883, sending 25 cubic kilometres of rock and ash into the air, it did more than generate the loudest sound ever recorded. It also cooled the world’s oceans and suppressed rises in sea level for decades afterwards.
What were the effects of the 1883 Krakatoa eruption?
and the bodies of victims were found floating in the ocean for months after
