Kirishima volcano news & activity updates
Kirishima volcano (Japan): seismic unrest
Tuesday Jul 28, 2015 10:26 AM | BY: T
Elevated seismic activity has been recorded since early July, the Japan Meterological Agency (JMA) reported. Yesterday, a phase of volcanic tremor occurred that lasted 3 minutes and a slight ground deformation was detected.
Whether this is caused by an intrusion of fresh magma which in turn could lead to a new eruption is unclear. For the time being, the volcano's alert level remains at 2 (out of 5) where it has been since Oct 2013. While the recorded signs of unrest are weak, sudden phreatic explosions could occur any time and pose a significant risk if visiting the crater area.

Kirishima volcano near Kagoshima town on Kyushu Island exploded violently earlier today (13 March), sending an ash plume to 4 km elevation. This is the first significant activity since March 1. It can not be ruled out, but probably remains speculation that the violent 8.9 magnitude earthquake on 11 March played a role in the reawakening of Kirishima. [more]
