The strait is dotted by a number of islands , many of which are volcanic in origin . They include : Sangiang ( Thwart-the-Way ) , Sebesi , Sebuku , and Panaitan ( Prince 's ) . The most famous volcano , however , is Krakatoa , which exploded in 1883 in one of the deadliest and most destructive eruptions in recorded history . The islands in the strait and the nearby surrounding regions of Java and Sumatra were devastated in that eruption , primarily due to intense pumice fall and huge tsunamis caused by the collapse of the volcano . The eruption drastically altered the topography of the strait , with as much as 18 – 21 km ³ of ignimbrite being deposited over an area of 1.1 million km ² around the volcano . Some areas , such as the coastal region of Java now incorporated into the Ujung Kulon National Park , have never been resettled , but much of the coastline is now very densely populated . Aside from Krakatoa 's sole remaining peak , Rakata , the Krakatoa Archipelago consists of the islands of Lang ( Panjang or Rakata Kecil ) , Verlaten ( Sertung ) , and most recently , Anak Krakatau , which emerged in 1927 from the original Krakatoa 's shattered remains
