Activity of Nevados of Chillan, Manam, Kadovar, Merapi, Krakatau and Etna.

An explosion partially destroyed the dome of the Nicanor crater at Nevados de Chillan this January 11 at 5 am local (8h UTC); it has been associated with an LP earthquake, in connection with fluid dynamics, at a depth of 500 meters and medium seismic energy.

Incandescence, and high temperature gas and pyroclastic material emission was observed in the active crater area.

The explosion remains within the current alert level, orange level.

In Papua New Guinea, after an eruption reported on January 8, a new eruption is reported in Manam.

The ash plume rose to 15.2 km, confirmed by VAAC Darwin and observers on the ground, then drifted to the SSO, passing on the Big Island. Mirova reports a very high thermal anomaly on January 11, with 1,414 MW, falling back to a more moderate level then, between 163 and 79 MW. The aviation code has changed to red.

Kadovar also has small intermittent eruptions in recent days. Small thermal anomalies are raised by Mirova on January 10, 8 MW, and January 12, 9-10 MW. The Darwin Vaac issued a volcanic ash advisory to the ESS on January 12 and an orange aviation code.

In Krakatau, the Sutseyan eruptions seem to calm down; the hydrothermal activity is manifested by intense outgassing around the volcano, and a brown water color towards Sertung Island, due to iron hydroxide particles, and greenish to the east, following differences in density .
