The scale of the dramatic collapse of the Indonesian volcano that led to last Saturday's devastating tsunami in the Sunda Strait is becoming clear. Researchers have examined satellite images of Anak Krakatau to calculate the amount of rock and ash that sheared off into the sea. They say the volcano has lost more than two-thirds of its height and volume during the past week. Much of this missing mass could have slid into the sea in one movement. It would certainly explain the displacement of water and the generation of waves up to 5m high that then inundated the...

Researchers have examined satellite images of Anak Krakatau to calculate the amount of rock and ash that sheared off into the sea. They say the volcano has lost more than two-thirds of its height and volume during the past week. Much of this missing mass could have slid into the sea in one movement. It would certainly explain the displacement of water and the generation of waves up to 5m high that then inundated the nearby coastlines of Java and Sumatra.

SUMATRA, Indonesia –Several earthquakes have struck near south Sumatra of the 5.0 and 5.1 magnitude range today- making a tense situation on the volcanically-dotted archipelago potentially even more volatile. The Anak Krakatau volcano is showing signs of increased seismic activity. Authorities fear the volcano is building towards an eruption that could dwarf the one which occurred in 2007. Indonesia’s Volcanology and Geological Disasters Mitigation Center reported the numbers of seismic tremors now registering from the volcano have exceeded 5,000 a day. There are also reports of a gaseous mist which has seeped from the volcano and have enshrouded it in...

VIVAnews - Mt Anak Krakatau, a volcano located on the Sunda Strait between Sumatra and Java, Indonesia, has seen escalating expulsion of toxic gas. The volcanic activities were triggered by 5.5 magnitude tremor hitting southwest of Krui, Lampung, earlier in November. In addition, the sea temperature around the volcano has been rising as well. According to Andi Arief, presidential advisor on Disaster Issues, revealed through a short message today, Nov 29, that the plumes of smoke sent off by the Anak Krakatau reached the height of between 200 and 800 meters into the air. The data gathered was an accumulation...

The Volcanology and Geological Disaster Mitigation Center (PVMBG) recommended Friday five regental administrations in Central Java distribute facemasks in anticipation of the spewing of thick ash from rumbling Mt. Slamet. The recommendation to the five regencies — Banyumas, Purbalingga, Pemalang, Tegal and Brebes — was made after seismic activity of the mount, which has begun spewing thick ash and molten lava from its crater, increased intensively. The recommendation was made after the alert status was raised to level three (of four) on Thursday evening, just two days after the status was raised to level two. "The local administrations should disseminate...

Jakarta, Detikcom - On Wednesday, Indonesia's Vice President Jusuf Kalla asked people living in area near of mount of Anak Krakatau (Child of Krakatoa) and Tangkuban Perahu to prepare from being evacuated. The VP announcement released as the danger level has been raised to level III on both volcanoes. ''We asked them to get ready, to be aware, but please don't be panic,'' said Kalla in his office in Jakarta. He added that the government would ask or order them to evacuate when the situation has reached level IV (four). ''They have to be evacuated when the level has reach...
