Volcanos

Roundup of Global Volcanic Activity:

White Island (New Zealand): Strong continuous volcanic tremor has returned and is now higher than ever, mixed with earthquakes. No unusual activity is visible at the surface.

Sangay (Ecuador): VAAC Washington reports pilot observations of ash emissions to 25,000 ft (7.5 km) altitude on 22 February. Since the volcano is very remote and one of Ecuador's most active, it is fair to assume that it might be in a state of elevated activity.

Heard (Australia, Southern Indian Ocean): A MODIS hot spot was visible yesterday at the summit of the volcano, despite the usual dense cloud cover. This indicates that some sort of activity likely continues.

Etna (Sicily, Italy): (23 Feb) The 5th paroxysm of the New SE crater is occurring. Tall lava fountains are erupting from the fissure vent of the New SE crater. This time, the eruption is much bigger than the previous ones. Judging from webcam images, lava fountains might be reaching one km in height.

Nevado del Ruiz (Colombia): (24 Feb) A small magmatric intrusion earlier today produced an earthquake swarm and increased SO2 degassing.
