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.

For reference the volcano in question is on an island just north of Sicily.

I tried to find that Channel 4 documentary from a few years ago about the MegaTsunami but it seems to have disappeared


Obviously nonsense that half the Island could collapse and even if it did, it may not trigger a large Tsunami that reaches America or us

I think you’ll find that the geological record shows that a tsunami has been triggered in the past by a collapse of that sort and that it isn’t just someone’s theory.

It was, as far as I remember, on the BBC (Horizon possibly)?

The satellite pic nicely shows an earlier eruption 'delta', complete with lava flow - not sure if that was from one of the relatively recent eruptions or a much older one? (Think that was also shown in a GeologyHub video on Youtube - usually interesting watches even if the chap doing them sounds more than a little monotonal/robotic!)


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

Yes, but I think there was a more recent one, perhaps it was Channel 5, it was more tabloidy and dramatic

More earthquakes overnight and a new lava stream has developed from the new fissures, which have become more active.

Yes, it’s not really showing any signs of slowing down. Here is (at time of writing) a live stream to several different feeds:

Plenty of experts have subsequently rubbished the theory - firstly on the basis that it's incredibly unlikely that half of Cumbre Vieja would simply slide into the ocean; and secondly that even if it did, any tsunami would be far less dramatic than the 'mega-tsunami' portrayed (2/3 metres at worst, rather than the devastating +50m portrayed)

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.

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.”

Flights to La Palma suspended again on account of volcanic ash, presumably because of it getting in to engines but could be runways covered in ash as well. TUI expecting this to last to end of October.
