An explosion marked the crater of Villarica this September 25 at 13:50 local / 16:50 UTC; an LP earthquake is associated with this moderate episode.
A plume of ash and gas rose to 800 m. above the crater, dispersing to the east northeast, and blocks were thrown around the crater.
A new emission of ash and particulate matter occurred at 6:29 p.m. local / 9:29 p.m. UTC
The volcanic alert level remains at amarilla.
The eruption continues in Suwanosejima, with this September 26 at 8:25 am local an ash plume, followed at 10:45 am local by an episode which produced an ash plume 1,400 meters above the crater, dispersing towards the southeast .
On September 24, 2020, Etna gives birth to a brilliant spectacle, with an explosion around 11 p.m., accompanied by loud rumbling (distinctly audible from ethnic countries). Material ejected from the mouth covered the entire NSEC (New South-East Crater) complex.
The National Institute of Geophysics and Volcanology, Etneo Observatory, announces that since 13:30 GMT on September 25 an increase in the intensity of explosive activity is observed at the new crater in the south-east; Strombolian-type activity produces fragments of lava thrown over the crater rim and a light and discontinuous emission of ash is dispersed in the atmosphere.
At the same time, a sudden increase in the amplitude of the tremor is observed. Such variations are part of a picture of large short-term fluctuations.
From the point of view of infrasound activity, no significant change is reported.
The signals from the GPS network and tilt from the INGV OE network do not show any significant variations.
Around 4.30 p.m. GMT, a marked decrease in explosive activity at the New Southeast Crater was observed; light and sporadic ash emissions persist and are dispersed
quickly in the atmosphere.
At the same time, a decrease in the amplitude of the volcanic tremor is observed with a return to average levels.

The Vanuatu Geohazards observatory recalls a major instability in Lopevi, on level 2 alert since September 23, 2017. the danger zone is limited to the island of Lopevi.
The active zone concerns the craters near the summit, where constant emissions of steam plumes are observed.
An eruption is likely to occur with few or no warning signs.
Lopevi is one of the many frequently active volcanoes in Vanuatu. Ash-producing eruptions can occur every 3 to 10 years. The volcano has been active during the historical period at the summit and flank vents, producing moderate explosive eruptions and lava flows that reached the coast. The historical eruptions date back to the middle of the 19th century. The island was evacuated following major eruptions in 1939 and 1960. Only one family tries to live on the island these days.
