Bromo volcano in Indonesia to re-energize

Centre of Volcanology and reduce geological risks (TSVSGR) Indonesia raised the level of anxiety in the located in the eastern part of the main Indonesian island of Java Bromo volcano to the second level ("alarm"), and forbade him to approach the crater closer than a kilometer.
"We are constantly monitoring the activity of the volcano and register it shake" - said the head of the publishing TSVSGR Surono (Surono).
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 eruption in 2004 killed two people. In late 2010, as a result of activation of another "fire mountain" there TSVSGR raised anxiety levels immediately before the fourth ("watch out!"), Bypassing the third, and forbade her to approach the crater closer than three kilometers. Indonesian authorities as a precaution, then shut down for a few days, the airport is located to the west of the city of Malang Bromo, and several international airlines canceled a few days lying on their flights to the east of Java island resort of Bali.
Bromo then some "cool down" to the level of anxiety on the slopes of the volcano has been reduced, but since the beginning of September this year, he again throws of at least 50 cubic meters of volcanic ash in the day.
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.
