On October 9, 2022 at 07:22 UTC / 09:22 loc., the Stromboli monitoring networks, managed by INGV and LGS, recorded the start of an effusive phase, which caused a collapse of the crater terrace; a pyroclastic flow was generated in the Sciara del Fuoco at 07:23 UTC, advancing a little at sea, and accompanied by a 3-minute seismic signal, and a slight tsunami of 2 cm., recorded at 07:24 UTC.

This pyroclastic flow was followed by other small pyroclastic flows which quickly reached the sea.

At 10:24 a.m., the INGV observed a well-fed lava flow reaching the coast. Explosive activity showed no significant changes.

Following the event, the monitored parameters showed a further increase in spattering activity localized in the NE crater sector, and accompanied by high tremor values.

The signals from the clinometric network of the TDF station show a very slight variation in intensity (0.05 microradians) between 7:15 and 7:30 UTC. There are no significant variations on the GNSS network.

The eruption of Nishinoshima continues with this October 8th a massive emission of ash in the atmosphere; the ash plume is seen in the Sentinel-2 image of the day.

On October 9 around 8:20 p.m. (11:20 UTC), the JMA reported an eruptive episode, accompanied by a colored plume at 2,900 meters asl., drifting northwest.

VAAC Tokyo issued several ash scattering notices on October 8 and 9. Several thermal anomalies, between 2 and 10 MW, are mentioned by Mirova.
