When did Krakatoa erupt the worst?
One of the most powerful volcanic eruptions in recorded history occurs on Krakatoa (also called Krakatau), a small, uninhabited volcanic island east of Sumatra and west of Java, on August 27, 1883.
Why did the Krakatoa volcano erupt in 1883?
It was the morning of August 27, 1883 that one of the world’s most astronomical eruptions occurred from the Krakatoa volcano. 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.

How powerful was the Krakatoa eruption?
Krakatau eruption is very very powerful, Krakatau volcanic explosion was equivalent to the power of 400 megatonnes of TNT. For comparison, the power of nuclear explosions that destroyed Hiroshima and Nagasaki was of 13-16 kiloton of TNT. And during the explosion, Mount Krakatau ejected no less than 21 km 3 ash, rock, and pumice.
