Perboewatan

Perboewatan (also spelled Perbuatan or Perbuwatan; apparently a Malay word of uncertain derivation) was one of the three main volcanic cones (the others being Danan and Rakata) on the island of Krakatoa (or Krakatau), in the Sunda Strait, in Indonesia.

Perboewatan was completely destroyed during the 1883 eruption; the caldera is approximately 250 metres (820 ft) deep at its former location.

This is backed up by Verbeek's visit in 1880, during which he took samples from a "fresh-looking" lava flow on the northern coast.

[citation needed] On 27 May 1883, the General Governor Loudon took a sight-seeing group of about 90 to Krakatoa, landing on the northern end of the island, just below Perboewatan.

In Rogier Verbeek's reconstruction of the eruption, Perboewatan is thought to have been the first cone destroyed, at about 4:40 am on 27 August.
