Of Bromo volcano lava flows


Indonesian volcano Bromo

JAKARTA, Dec 30 — RIA Novosti, Mikhail Tsyganov. Indonesian volcano crater of Bromo, located in the eastern part of the country's most populous island of Java, last night began outflow of lava, reports on Thursday the national Antara news agency referring to the Indonesian volcanologists.


"Burning lava erupted at night", — said one of the leaders of the Centre of Volcanology and reduce geological risks (TSVSGR) countries Gede Svantika (Gede Suantika).

According to him, Bromo, known as the most beautiful "fire mountain" in Indonesia, where the only active volcanoes, there are over a hundred, for the past 11 days, emits clouds of ash to a height of up to two kilometers, and a layer of ash in the vicinity of the volcano height of 2.329 thousand meters above sea level has reached a thickness of 30 centimeters.

At the same time, said Svantika, beginning until the expiration of lava extended beyond one hundred meters from the crater, and therefore does not currently pose an immediate threat to local residents.

Bromo is relatively small and is located far from the nearest major population centers — in the center of the rest of the ancient supervolcano eruption of the caldera on a high plateau Tenger. In the XX century the volcano erupted three times, and its last eruption in 2004 killed two people.

This year TSVSGR in late November raised the level of anxiety out there on the second level ("alarm") immediately prior to the fourth ("watch out!"), Omitting the third, and forbade him to approach the crater closer than three kilometers. Indonesian authorities as a precautionary measure in early December was closed for several days, the airport is located to the west of the city of Malang Bromo over concerns that already hanging in the air, the ash cloud could threaten the safety of the area.

But then Bromo calmed down, the level of anxiety on the slopes of the volcano has been reduced to a third, and began outflow of lava has not yet led to a revision of this status.

However, the eruption of one of the most visited volcanoes in Indonesia and the continued ban on approaching Bromo of less than 2.5 kilometers already deprived of livelihood to 25,000 residents living on tourist services, and forced the local authorities to enter into them to provide food assistance.

The third level of anxiety is now preserved on the slopes of Mount Merapi in Central Java, whose eruption in October-November, claimed the lives of hundreds of people.

The third of the Indonesian volcano, which is now declared to alert the third degree is a mountain on the island of Halmahera Ibu in eastern Indonesia.

World's largest Indonesian archipelago is part of the so-called Pacific "Ring of Fire" — the band of volcanoes and tectonic faults up to 40,000 kilometers. In the region of Indonesia plates that form the bottom of the Indian and western Pacific oceans, but with the Asian. Advancing to the last denser oceanic tectonic plate under enormous pressure down to the mantle of the world and at a depth of about 100 kilometers below the surface begin to melt, resulting in the release of the resulting molten lava.

Therefore, the length of the Indonesian part of the "Ring of Fire" (3.218 thousand kilometers) are volcanoes.
