Indonesia belongs to one of the most volcanic and seismically active regions in the world. There are 128 active volcanoes of which 76 had eruption in historic time. These occurred in 3 belts one of which is the Lesser Sunda Islands where Krakatau is located. The Indonesian Volcano Logical Service classified those volcanoes as "class A" volcanoes, of which there are 12 in Sumatra Island. One of those is Krakatau. Krakatau is located in the South Lampung region in the Sunda Strait, between Java and Sumatra.
In the early times, Krakatau was a volcano with 2000 M in height. The catastrophic eruption destroyed the volcano and remained 3 islands i.e. Rakata, sertung, and Panjang. The renewed activity was started at Rakata, and the island of Strato Volcano was built with a diameter of approximately 5 Km and 800 M high. After its dormancy, the next activity was shifted and came into existence with a height of approximately 456 and 120 M above sea level.
In 1883, the 3 summits (Rakata, Danan & Perbuatan) erupted leaving a small part of Rakata. The boom of the explosion caused tremors and was heard as far as Singapore and Australia. The wave washed everything away around the volcano. The volcanic ash was blown into the atmosphere, as much as 4 cubic miles. In 1927 new activity occurred and then Anak Krakatau came into being. Now Anak Krakatau has reached 250 M above sea level. Anak Krakatau is still active with its gush of steam and smoke, making it a spectacular view.
Today we can come and step our foot on it searching closely for the minerals (Volcanic bomb, lava, lapel) from the bottom of the earth that were thrown up through its crater. Krakatau and its terrific eruption, which is recorded in history, now invite everyone to come and see it for science as well as for pleasure. The way to get there is from Canti located in Kalianda about an hour's drive from Bandar Lampung, and the boats will take to the Karakatau area. Near Krakatau, there are Sebuku and Sabesi Islands for stopover and staying overnight. It is only taken one and a half hours from Canti.
