Volcanos

Wind kicks up ash from eruption of remote Alaska volcano 100 years ago - A smog-like haze that hung over part of Alaska's Kodiak Island this week was courtesy of a volcanic eruption — 100 years ago. The National Weather Service said strong winds and a lack of snow Tuesday helped stir up ash from the 1912 eruption.


Global Volcano Activity Today:


The seismic swarm in the Tjörnes Fracture Zone north off Iceland continues into its 10th day and the frequency of quakes has even picked up again a bit. An warning for a possible larger earthquake remains in place.


3 small phreatic explosions occurred at Poas volcano in Costa Rica on Sunday 29 Oct.


Popocatépetl's activity remains fairly stable [Mexico]. The volcano continues to glow at night and produced 1-2 weak explosions per hour, sometimes with small ash plumes. A local news article mentioned light ash fall occurred in some nearby areas.


Fuego volcano [Guatemala] continues with mild infrequent strombolian explosions and an active lava flow towards the Ash Canyon about 400 m long.


A strong SO2 plume can be seen from Ambrym volcano on Vanuatu on 30 Oct, where several lava lakes are quite active.


Sakurajima volcano [Japan] had 2 moderately strong explosions on 29 and 30 Oct with ash plumes reaching 3-3.4 km altitude.
