Why did mount Krakatoa explode?

Answer 1

Krakatoa's explosion was probably due to shifts in the crust of the earth below the site that resulted in the upwelling of a large quantity of magma. Additionally, faulting and subsiding may have permitted seawater to enter magma chambers. This would have cooled and solidified magma, thus "capping" the chamber(s) and allowing pressure to build to the point the island exploded to release the pressure.

Answer 2

* The volcano's vents had sunk below sea level on the morning of 27 August, so seawater flooded into it and caused water to react with magma * The seawater could have cooled the magma down, and that could have caused more pressure to build up * Hot magma was mixed with the cooler and lighter magma in the chamber below the volcano. This would have made a rapid increase in pressure, leading to an explosion.

Answer 3

It is believed that the 1883 eruption was triggered by basaltic magma being injected into the magma chamber beneath he volcano. This basaltic magma was hotter and more fluid than the magma already present. This set the stored magma moving, allowing it to move to the surface through the volcano. As the magma approached the surface the decreasing pressure allowed gasses trapped in it it expand explosively, ejecting the magma to produce fine particles of ash. As large quantities of magma were drained from the magma chamber, the volcano began to collapse into the space left behind. This brought magma into contact with seawater, resulting in a series of massive explosions.

Answer 4

Mount Krakatoa exploded in 1883 due to a buildup of pressure from the release of magma and gases within the volcano. This buildup of pressure eventually led to a massive eruption that resulted in the collapse of the volcano's structure and caused a series of devastating tsunamis.

Answer 5

Some one took a massive dump on it and they boy krakatao didnt like it

Answer 6

Krakatoa exploded, in theory, because of a pressure build up, the magma in Krakatoa clogged up, after a while the mountain couldn't take the pressure and exploded with great force.

Answer 7

Krakatoa collapsed because the eruption drained an enormous volume of magma from underneath. The ground collapsed into the space left behind.
