The persistent activity since the beginning of the month at the summit of Mount Etna evolved yesterday towards repeated strombolian explosions at the southeast crater, while incandescence persists at the Voragine.

In Bogoslof, an ongoing seismic swarm follows those recorded on 10 and 11 March, which did not lead to any significant activity.


The volcano remains unpredictable. Its last explosion, on 8 March, produced changes both in size and form of the island. The most active vent is always located underwater in the center of the island, and has been greatly expanded by the last eruption. A new vent is seen on the north shore, while the west coast line has grown.

In Guatemala, the Pacaya is characterized by the expulsion of lava, a gray-colored plume, and mild and sporadic explosions.
