The Center for Volcanology and Disaster Mitigation, Geological Agency, Ministry of Energy and Mineral Resources Surono states is possible eruption of Mount Merapi this time of explosive and spread in all directions.
"It was during this tendency is to form a dome of Mount Merapi and after that the dome carried along with a blast of heat clouds, but from historical explosive eruptions have also occurred and did not form a dome first," said Surono in Yogyakarta, on Friday night.
Met on the sidelines of the opening "Merapi Volcano Expo 2010" in the Office of Investigation and Technology Development Center Kegunungapian (BPPTK) Yogyarkarta, he said, in 1930 and 1931 explosive eruption of Mount Merapi and the radius of the eruption could reach more than 15 kilometers.
"Even for a rain of ash in explosive eruptions reached Madura and Malang, East Java," he said.
He said the current pattern of volcanic activity is different from the pattern of tooth eruption in 2006 both in terms of volcanic seismicity as well as from the mark-strong body which is also very fast mount.
"The pattern is indeed there are similarities with the 1931 eruption is rapid increase in activity and strength of a larger volcanic earthquakes," he said.
Surono said, but this is only an estimate scenario for what will happen with the eruption of Mount Merapi, no one can predict, including the time and amount of material.
"For example the eruption of Mount Kelud in Kediri, East Java in 2007, when it was so strong seismicity and large similar to an explosive eruption in 1990, reaching a radius of 10 kilometers. Once in a radius of 10 kilometers of security we did was in 2007 a small eruption only once and only form a dome, "he said.
He said that if Merapi volcano will soon erupt in the near future it can not be sure.
"What is clear Merapi will never break a promise, after the increased activity usually ends with an eruption that can be shaped dome and pyroclastic avalanches or explosive eruption, they only know of Merapi," he said.
