Kirishima volcano (Kyushu, Japan): warning to approach Iwo crater
Mon, 29 Feb 2016, 18:4018:40 PM | BY: T
A "near-crater" warning was issued for the volcano by JMA (Japan Meteorological Agency), in particular for the Iwo crater where an increase in seismic activity, fumarole temperatures and degassing (including poisonous H2S) in an area about 100x100 m wide has been observed over the past months.

The observed signs of volcanic unrest are considered weak and no eruption is expected in the near future, but the risk of (always possible) sudden, steam-driven explosions, which could affect an area of up to 1 km radius, needs to be considered elevated. The site, a popular excursion destination and easily accessible by road, has been closed for public access now. A similar warning had already been issued in October 2014 and lifted again in May 2015.
