Krakatoa volcano

At about 13:00 (local time) on 26 August, 1883, the Krakatoa volcano went into its paroxysmal  phase, and by 14:00 observers could see a black cloud of ash 27 km high. At this point, the eruption was virtually continuous and explosions could be heard every ten minutes or so. Ships within 20 km of the volcano reported heavy ash fall, with pieces of hot pumice up to 10 cm in diameter landing on their decks. A small tsunami hit the shores of Java and Sumatra some 40 km away between the time of 18:00 and 19:00 hours.

Krakatau Festival aims to attract tourists to Lampung, Indonesia

Hundreds of active volcanoes that dot the Indonesian archipelago not only threaten the population, but they have also given life to its people over many centuries.
These wonders of nature are a big draw for tourists. One such attraction is Anak Krakatau - an undersea volcano - in the Sunda Strait.
Lampung, a province at the southern tip of Sumatra, has been celebrating for over a month. Ironically, the yearly festival commemorates the eruption of Krakatau.

Erupting Volcano Anak Krakatau
The volcano on Krakatoa is still erupting. Perhaps most famous for the  explosive eruption in 1883 that killed tens of thousands of people. Ash from a violent eruption might also have temporarily altered Earth's climate as long as 1500 years ago.

This week marks the 125th anniversary of the devastating eruption of the Indonesian volcano, now an unusual tourist attraction, despite being active. Or because of it...
Indonesia's Krakatoa volcano erupted. It did so with the force of 13,000 Hiroshima atom bombs, propelled a trillion cubic feet of rock, pumice and ash into the air, and made a noise loud enough to be heard 1,930 miles away in Perth. The explosions, fallout and resulting tidal wave (130 feet high in places) killed 36,417 people in Java and Sumatra, destroyed 165 villages and towns, and two-thirds of the island. Wind streams blew the fine ash as far away as New York; sea levels were raised in the English Channel, and over the following year, global temperatures were reduced by 1.2C.

The Anak Krakatoa (Child of Krakatoa) volcano sends up powerful clouds of hot gases, rocks, and lava this week in the Sunda Straits between Java and Sumatra. The eruption was nothing compared with what took place in 1883 at this spot, when the original Krakatoa  blew apart in one of the most devastating eruptions in recorded history.

Sending a boom across the bay, the offspring of the fabled Krakatau volcano unleashes another mighty eruption, blasting smoke and red-hot rocks hundreds of feet into the sky.
Even on its quiet side, the black sand on the now-forbidden island is so hot that a visitor can only briefly set foot on it.

Anak Krakatau's volcanic activity has increased over the past three days, prompting Indonesian authorities to warn tourists and fishermen not to go near the volcano.
Over a period from October 24 to 26, the volcano had produced 20 tremors and released 80 to 200-meter-high grey smoke plumes every hour.

Thanks to a spectacular volcanic explosion in the late 19th century, global warming and sea-level rise over the last century haven't been quite as severe as they might have been otherwise, scientists at Lawrence Livermore National Laboratory and elsewhere say.

The 1883 eruption of Krakatoa in the Sunda Strait of Indonesia spewed so many particles into the sky that the world's sunsets turned an eerie reddish colour, inspiring painters as far away as Europe. The explosion's gases and dust also blocked sunlight and cooled the planet by an average of about 1 degree well into the 20th century.
Now the scientists have reported a surprising finding. A legacy of the explosion persists beneath the ocean surface: a vast layer of cold water chilled by the nuclear-bomb-class volcanic detonation of 1883.
