After a long period of inactivity (about 200 years), Krakatoa became active again in early 1883. The first indication that something was happening on Krakatoa was when a large earthquake struck the area. Seismic activity became stronger until May 20,1883, when the volcano abruptly came to life. The initial explosive eruptions of Krakatoa could be heard 160 km away. Steam and ash could be seen rising 11km above the summit of the volcano. By August 11, 1883. three vents were actively erupting. Eleven other vents were ejecting smaller quantities of steam, ash and dust.

Around 1 pm on the 26th of August 1883, the explosions became more frequent occurring on the average every 10 minutes. Sailors on a ship, 120 km away from the island reported a black cloud of smoke rising above the volcano. At the time the rim of Krakatoa's crater was approximately 1,000 meters in diameter and had and average depth of 50 meters. The volcano' s central vent was blocked by a plug of solid lava and underneath it pressure was rapidly building up.

The renewed activity in May 1883 culminated in four gigantic explosions on August 26 and 27 of the same year. On the afternoon of August 26, 1883, (27 August local date) at 17: 07 Greenwich time (GMT), the first of these four violent explosions begun. A black cloud of ash was initially observed. It rose 17 miles (27 kilometers) above Krakatoa. In the morning of the next day, on August 27, 1883, at 05:30, 06:44 and 10:02 GMT, three more violent eruptions occurred. It was the paroxysmal eruption which occurred at 10:02 which blew away the northern two-thirds of the island. This was the most severe violent volcanic explosion on Earth in modern times. The explosion was followed by the collapse of the unsupported volcanic chambers of Krakatoa forming the huge underwater caldera. It was this explosion and collapse of Krakatoa that generated catastrophic tsunami waves as high as 37 meters. (120 ft.) that caused havoc and destruction in the Sunda Strait.

Impressive block of coral!

[Lil Stinker]

Extremely interesting info and pics. Thanks for sharing!

Also Dr. PC's pages are FASCINATING!! A great read, great find!

I bet it could be heard farther than that.

Volcanoes leave an appalling 'carbon footprint'

It was heard in Perth quite clearly, 3500km away

Actually there is very little carbon in magma, human activity produces more greenhouse gases in one week than the combined eruptions of the last 50 years

That's such an epic picture!
