Etna (Sicily, Italy): A small event this morning at 08:09 (local time) from the New SE crater produced a reddish-brown ash plume generated by partial collapse on the eastern flank of the cone

Bagana (Bougainville Island, Papua New Guinea): (11 Apr) A major magnitude 7.2 earthquake struck 50 km south of the volcano today.

Momotombo (Nicaragua): (11 Apr) A shallow magnitude 6 earthquake occurred last evening 15 km NE from Momotombo volcano, followed by ongoing numerous aftershocks in the area east of the volcano, as well as near Apoyeque volcano on the peninsula in Lake Managua to the SE.
The quakes are probably tectonic in origin, and INETER has not reported any unusual activity at the volcanoes. On the other hand, earthquakes of this size could disturb the plumbing system of the volcanoes and potentially help trigger new activity.

Nyamuragira (DRCongo): According to local news, a seismic crisis is under way at the volcano and the volcano observatory in Goma thinks that a new eruption in coming days or weeks is likely.
"The eruption of Nyamulagira will have no impact on the famous volcano Nyiragongo, whose activity is in a normal state," said Kaco Karume, member of the Volcanic Observatory of Goma (OVG).
Nyamuragira (also spelled Nyamulagira) volcano is located 22 km north of Goma, the capital of North Kivu province. It erupts on average every 2 years. Its last eruption was in late 2011-early 2012.
