Volcanic Activity Worldwide: Friday May 27, 2016

Strombolian activity from Etna’s Voragine on Wednesday

Etna (Sicily, Italy): The violent strombolian activity from the Voragine summit crater continued all though Wednesday (25 May) and the following night, but gradually decreased and ceased yesterday. At the moment, no significant eruptive activity is going on.
To see images and videos of this recent activity, you could visit the facebook page of the mountain guides from Etna Nord.
At the moment, tremor is still elevated and seems to be increasing slowly again – maybe some new pulse of activity is in the making?

Piton de la Fournaise (La Réunion): The first eruption of the volcano in 2016 seems to have ended already – or at least paused – after little more than 24 hours. The volcano observatory reported that eruption tremor and other signs of ongoing activity stopped at 11:40 this morning.
During brief windows of clear weather, it was possible to observe the eruption yesterday. A curtain of lava fountains, up to approx. 50 m high, was erupting a branching lava flow from a fissure vent in a flat area 1850 m above sea level about 1 km-1.5 km southeast of Château Fort crater, and built up an elongated cinder cone above the vents.
Such short eruptions (few days only) are not unusual for Piton de la Fournaise volcano. Often, they have been occurring in relatively rapid succession (few weeks intervals), or preceding larger and long-lasting ones.
