Tokyo, Aug. 14 (Jiji Press)--The Japan Meteorological Agency on Friday raised the volcanic alert for Mount Aso in the southwestern prefecture of Kumamoto to Level 3 from Level 2, banning entry to the mountain, due to increased volcanic tremor amplitudes and rapidly growing volcanic gas emissions. At a press conference in Tokyo, Atsushi Fuji, director of the agency's Volcanic Observation Division, called for caution over large volcanic rocks and pyroclastic flows, a mix of high-temperature fragments of volcanic origin such as molten rocks, ash and gas, in areas within about 2 kilometers of a crater of Nakadake, one of the five peaks of the volcano. Fuji said that "we cannot clearly say with a scientific basis" about the relationship between the volcanic activity and a powerful earthquake that hit the prefecture July 28. On June 21, the agency raised the volcanic alert for Mount Aso to Level 2 from Level 1, prohibiting approaches to areas around the craters, following increased volcanic activity. Level 1 suggests a potential for increased volcanic activity. END [Copyright The Jiji Press, Ltd.]
