MOUNT KRAKATAU

Krakatoa (or Krakatau)


Krakatoa or Krakatau, was a small volcanic island in the Sunda strait, about half way between Java and Sumatra.


In 1883 an eruption of Mount Krakatoa (sometimes spelled Krakatau) with a force greater than that of several hydrogen bombs caused tidal wave (tsunami) that submerged the coast of the island of Java, killing thirty-six thousand people. The eruption destroyed most of the existing islandsof the Krakatao surrounds. Then new eruptions at the volcano since 1927 have built a new island, called the child of Krakatao, Anak Krakatau.

Anjer is located on the Western coast of Java, at 26 miles (40 Kms) from the Volcano.
At that time the Dutch East India Company (Vereenigde Oost-Indische Compagnie or VOC) was governing the island of Java.

1883: the explosion

The fist alert reported in May 1883 by The Times of London.

" On Sunday morning last, from six to ten o'clock, there was a tremendous eruption, with continuous earthquakes and heavy rain of ashes.
On Sunday evening and Monday morning, it was continued. The eruption was distinctly seen here until nine o'clock this morning, and the smoke was seen until twelve o'clock; afterwards it cleared up a little, and at this moment the air is clouded again.
The Captain Ross reports from Anjer that, on May 22, he was sailing near Java's Fisrt Point and tried to get Prinsen Island in sight, but found that it was surrounded by clouds. Then he steered from Krakatan, but found it to be the same there. the captain observed that the lower island or mountain situated on the north side of Krakatan was totally surrounded by smoke, and from time to time flames arose with loud reports.
Fire had broken out in several places, and it is very likely that the trees in the neighbourhood have caught fire. "

The event: Monday, August 27, 1883 at 10:02 am.

At that very moment came the culminating and terrifying main eruption of the Krakatoa. Krakatoa's final twenty hours and fity-minutes were marked by a number of phases. It started by a series of explosions on Sunday at about 7 p.m. The explosion was so huge that most of the volcano's mountain (or island) desapeared under the level of the sea. A new smalest volcano island was formed later on, and called Anak Krakatoa.

This eruption of August 1883 was the largest recorded in Java, and is considered as one the world's biggest volcano explosion recorded by human in the last centuries, with the Tambora Volcano in Sumbawa on April 1815, an other Indonesian island. Coming back to the Krakatao eruption, the sound was so loud that it was heard in Thailand and in Australia. Some studies are also pointing out thet the smoke was so important that it propagated in the atmosphere for months, generating climate modification in an extended portion of the globe.
