Mt. Kirishima ready to erupt.
24 FEBRUARY 2016. Scientists in Japan say another volcano is showing signs of being ready to erupt. Mt. Kirishima on Japan’s western Kyushu Island last erupted in 2011. Authorities say 158 tremors registered Tuesday at the Shinmoe Peak.
Experts from Japan’s meteorological agency surveyed the peak’s surface temperature and other data Wednesday, but detected no abnormalities. Still, they said a small eruption is possible and kept the warning level at 2. That means hikers must act with caution when approaching within half-a-mile of the caldera.
Kirishimayama is a large group of more than 20 Quaternary volcanoes located north of Kagoshima Bay. The late-Pleistocene to Holocene dominantly andesitic group consists of stratovolcanoes, pyroclastic cones, maars, and underlying shield volcanoes located over an area of 20 x 30 km. The larger stratovolcanoes are scattered throughout the field, with the centrally located, 1700-m-high Karakunidake being the highest. Onamiike and Miike, the two largest maars, are located SW of Karakunidake and at its far eastern end, respectively. Holocene eruptions have been concentrated along an E-W line of vents from Miike to Ohachi, and at Shinmoedake to the NE. Frequent small-to-moderate explosive eruptions have been recorded since the 8th century.
