Volcanos

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): Mild explosive activity continues at the New SE crater with little variation, but has now essentially become continuous. Weak lava effusion also continues to aliment small flows from vents at the eastern base of the cone. The tremor shows a fluctuating, but overall slowly increasing trend.

Hekla (Iceland): The volcano has drawn media attention and is being closely monitored as it is believed it is "ready" for a new eruption (although there are no current indications that one is imminent). A recent statement by Páll Einarsson, professor in geophysics at the University of Iceland, made headlines saying that "Hekla might eruption soon", because GPS deformation and strain measurements suggest that its shallow magma reservoirs have been filling up during the past years.

Colima (Western Mexico): The volcano produced a series of small ash puffs last night (23:00 GMT). VAAC Washington alerted of low ash plumes beneath flight level 150 (15,000 ft / 4.5 km altitude) drifting east from the volcano.

Poas (Costa Rica): Another moderately sized phreatic eruption from the crater lake of the volcano took place yesterday morning at 07:08 local time. The explosion ejected steam, water, mud and rocks to about 100 m height.
