Anak Krakatua

Reference



I think that means 'Son of Krakatoa', to the use 1883 spelling.

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. The eruption also affected the climate and caused temperatures to drop all over the world.

The big blast was a classic boiler explosion, about 200 megatons.  Seawater hit the magma chamber and flashed to steam under high pressure.  It was heard thousands of miles away.



It is located on top of a very active subduction zone.  You can see how clean it is, and that means an M9 earthquake every 3-500 years.  The big 2004 tsunami was just up a bit, and we can expect another one on the lower section 'soon', give or take 100 years.  The volcano is at the red dot, and is famous because it is in the sea.  There are lots of other big volcanoes around.



That's the remaining cluster after the big explosion of 1883. 


The little guy has a while to go before he builds up to be like dad before the big blast.
