Kirishima volcano (Japan): seismic unrest
Dienstag Jul 28, 2015 10:26 | VON: 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.

The Japan Meteorological Agency issued a "near crater warning" for the Shinmoedake vent of Kirishima volcano last Friday. Increased earthquake activity were detected and mean an increased risk of a possible (probably phreatic) explosions. ... [mehr]

The alert level of the volcano was lowered back to 1, as volcanic activity continued to decrease. Volcanic seismicity remained at low levels and no remarkable change was observed from ground deformation observation and monitoring data. ... [mehr]

No eruptions were observed at Shinmoedake since 7 September 2011 (last explosion on 1 March). Overall, the volcano's activity (seismicity, deformation, degassing) has been decreasing, JMA's November volcano activity summary reports: ... [mehr]

Wie unser Kollege Marc Szlegat auf Vulkane.Net berichtet, wurde bereits im letzten Monat am japanischen Vulkan Kirishima (Kirishimayama) im letzten Monat die Warnstufe auf “orange” erhöht. Das ist die 3. von 4 Warnstufen und bedeutet, dass jderzeit mit einem Ausbruchgerechnet werden kann. ... [mehr]

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. [mehr]
