22 October-28 October 2008

On 27 October, JMA raised the Alert Level for Kuchinoerabu-jima from 2 to 3 (on a scale of 1-5). GPS measurements indicated that inflation just below the summit crater, which had started in September, was continuing. Fumarolic activity near summit had also increased. On 4 September, JMA had raised the Alert Level for from 1 to 2 because of the increased seismicity.

A group of young stratovolcanoes forms the eastern end of the irregularly shaped island of Kuchinoerabujima in the northern Ryukyus, 15 km west of Yakushima. Furutake, Shintake, and Noike were erupted from south to north, respectively, to form a composite cone that is parallel to the trend of the Ryukyu Islands. The highest peak, Furutake, reaches only 657 m above sea level. The youngest cone, 640-m-high Shintake, was formed after the NW side of Furutake was breached by an explosion. All historical eruptions have occurred from Shintake, although a lava flow from the S flank of Furutake that reached the coast has a very fresh morphology. Frequent explosive eruptions have taken place from Shintake 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.
