I find it a little disturbing that the quakes are continuing despite the ongoing eruption. Often such activity dies down as pressure is released. It makes me wonder if there are still a few developments to come (more fissures or more violent eruption). |

Vulcano Island in Aeolian Sea looks like it could erupt in the near future; there is elevated fumarolic activity there.

On the Icelandic side of things and still no lava from the current eruption site although increased earthquake activity certainly suggests lava is on the move and may break out over the next couple of weeks. In some ways the current location was pretty perfect as it was close enough to the road that setting up cams and allowing public access was easy but with enough valleys to contain the lava flow without it causing any damage to infrastructure. Whether a new site would be so conveniently located is debateable, with it being much more likely to cause damage to roads if nothing else. No guarantees the lava will make it so the surface of course, be interesting to see what happens |

Possibly one for the earthquake thread?  While it was a large quake I think the depth (over 500km) meant any impacts were limited. Meanwhile La Palma’s volcano is still looking very active with lots of thick black ash being emitted currently and quite a few quakes greater than magnitude 3. https://youtu.be/DFzZyTFQWo8 |

Further update https://www.volcanodiscovery.com/lapalma/sep2021seismic-crisis/current-activity.html
“Earthquakes continue to occur and have been slowly increasing in numbers and magnitudes approaching magnitudes of 4.0 now. During the past 24 hours, there have been 31 quakes of magnitudes 3.0-3.9 and 47 quakes between 2.0 and 2.9, while smaller quakes cannot be detected due to the volcanic tremor noise.
While most of the quakes are still 10-15 km deep under the central area of the volcano, a cluster of new, deeper quakes has appeared at depths around 35 km under the northeastern flank. What these mean is uncertain, but they might reflect even deeper magma intrusions in the upper mantle, perhaps suggesting that a magma supply system is establishing itself from a very deep source. That in turn could mean that the eruption could be going on for a very long time.”
