The eruption on August 27, 1883 was an explosive eruption: the pressure from expanding magma blew away most of the main island, reducing it to rubble and ash that was thrown 50 miles into the air. The energy of the main eruption was equal to that of a 200 megaton nuclear blast, and there were tsunamis from all 4 main eruptions that day. The remnants of the island subsided into the empty magma chamber beneath the islands.
Another result indicating the intensity of the blast was that a 10-ton mass of coral was uprooted and rolled up onto the Java shore more than 20 miles away.

Is Krakatoa a explosive or non-explosive?
Krakatoa is a volcano that erupted. In the eruption, gases were trapped below the cap of the volcano. The explosive eruption occurred when the pressure was enough to blow the cap off of the volcano.
What eruption type was the Krakatoa eruption in 1883?
The Krakatoa eruption in 1883 was a Plinian eruption, which is a highly explosive volcanic event characterized by the eruption of vast amounts of ash and volcanic material into the atmosphere. The eruption of Krakatoa was one of the most powerful volcanic explosions in recorded history.
Was Krakatoa in 1883 more explosive than Mt St Helen's in 1980?
Yes, far more explosive. The eruption of Krakatoa was more than 10 times larger than the 1980 eruption of Mount St Helens.
Was mauna loa a quiet or explosive eruption?
No, Mauna Loa is not an explosive volcano. It tends to be non-explosive.
Why was the eruption of Krakatoa in 1889 so explosive?
The eruption of Krakatoa in 1883 was so explosive due to the accumulation of high-pressure magma beneath the volcano, which eventually led to a catastrophic release of energy. The eruption was triggered by the collapse of the volcano's magma chamber, resulting in a series of powerful explosions that generated massive tsunamis and global climatic effects.
