Volcanoes getting active during this week: 1) Nishino-Shima volcano (Izu Islands, Japan): new island continues to erupt and build a new cone 2) Sakurajima volcano (Japan), activity update: strong explosions and near constant ash emissions 3) Sinabung volcano (Sumatra) - increasing activity, ash plume to 25,000 ft 4) Fuego volcano (Guatemala): small paroxysmal eruptive phase with frequent strombolian explosions 5) Santa María / Santiaguito (Guatemala): No significant changes in activity occurred. Explosions generate ash plumes as high as 900 m above the dome and effusive activity continues to produce small lava avalanches mainly from the NE flank of the dome. A felt earthquake occurred yesterday night at 00:32 local time. 6) Chaitén volcano (Chile): increased seismic activity 7) Etna volcano (Sicily): The eruption today was much faster than the previous ones, but the peak phase of lava fountaining, which only lasted about one hour, was particularly intense. It produced tall fountains and a large ash plume of about 6 km height that drifted to the NE (towards Taormina) where heavy ash fall occurred. 8) Colima (Western Mexico): Lava avalanches and flows continue to spill down the upper flanks. 9) Popocatépetl (Central Mexico): The rate of emissions has dropped to less than 10 per day. Glow remains visible from the summit crater at night, indicating that magma continues to arrive (slowly). A small volcanic-tectonic quake of magnitude 2.0 occurred yesterday morning (CENAPRED).
