JMA reported that no eruptions occurred from Kuchinoerabujima during 9-16 February although the level of activity remained elevated. White plumes rose 400-700 m above the crater. Low-level seismicity continued and tremor was absent. Scientists aboard an overflight on 10 February observed a new crater with high-temperature areas on the NE part, new fissures, and white steam emissions. The Alert Level remained at 3 (on a scale of 1-5).

Geological Summary. A group of young stratovolcanoes forms the eastern end of the irregularly shaped island of Kuchinoerabujima in the northern Ryukyu Islands, 15 km W of Yakushima. The Furudake, Shindake, and Noikeyama cones were erupted from south to north, respectively, forming a composite cone with multiple craters. All historical eruptions have occurred from Shindake, although a lava flow from the S flank of Furudake that reached the coast has a very fresh morphology. Frequent explosive eruptions have taken place from Shindake since 1840; the largest of these was in December 1933. Several villages on the 4 x 12 km island are located within a few kilometers of the active crater and have suffered damage from eruptions.
