The Japan Meteorological Agency announced that Mt. Aso, located in central Kyushu, could soon erupt explosively. The announcement, made by the JMA's Coordinating Committee for Prediction of Volcanic Eruptions, does not specify the approximate timing or intensity of the expected eruption.
Mt. Aso has been relatively quiet since April 14 this year, when an explosion occurred sending a white plume of smoke into the air and depositing ash around the crater.
