Why did Krakatoa erupt so violently?

Originally Verbeek thought that Krakatoa was so fierce because sea water flooded into the volcano, reacting with molten lava; the build-up of pressure from the resulting steam would have led to an enormous blast. His model left a crater and landslide scar very like the remains of Krakatoa.
