...I saw with amazement that the island of Krakatoa, on my first trip to Sumatra [June 1679] completely green and healthy with trees, lay completely burnt and barren in front of our eyes and that at four locations was throwing up large chunks of fire.he eruption destroyed two-thirds of the island of Krakatoa. Eruptions in the area since 1927 have built a new island at the same location, named Anak Krakatau (which is Indonesian for Child of Krakatoa). Periodic eruptions have continued since, with recent eruptions in 2009, 2010, 2011, and 2012.
