Volcanos

Roundup of Global Volcanic Activity

Etna (Sicily, Italy): It seems that a new episode of strombolian activity has started at the New SE crater a few hours ago. Visibility is not very good, but bright glow and rising tremor suggest that a new eruptive phase is in progress. A new pit crater had been observed on the upper eastern flank of the New SE cone, which had been degassing strongly. In the meanwhile, the strombolian activity inside Voragine had also continued during the past days, occasionally even strong enough to project bombs higher than the rim of the crater.

Momotombo (Nicaragua): As this morning's webcam images already had suggested, a new fully-blown magmatic eruption is now in progress at the volcano: pulsating lava fountains (or continuous, strong strombolian activity) feed a new lava flow that slowly descends on the NE side of the volcano, and a dense ash plume that rises approx. 2-2.5 km above the volcano and drifts NW.
