La Palma volcano eruption update: activity remains intense with lava fountains and ash emissions
Fri, 26 Nov 2021, 15:53
15:53 PM | BY: VOLCANODISCOVERY


The activity remains elevated. After yesterday's surges of lava from a new fissure system south of the cone, lava fountains returned to the main vents at the cone, first in form of a round dome-shaped fountain of very liquid lava from the lower vent (see previous update with video), and later as a taller, more gas-rich jetting fountain from the summit vent which had been very active especially in the early phase of the eruption.
The latter activity has continued throughout a very stormy and rainy night and into this morning, then decreased a bit although it still produces fountains as of this update. The generated ash plumes rose to up to 3,500 m altitude and drifted east where it continues to disable the airport, now closed for 6 or 7 days in a row. Many airlines have canceled flights to La Palma altogether for the whole time up to spring next year due to the uncertainty whether the airport is operational or not, and whether they can actually fill seats. Requests to travel to the island likely have dropped massively, further damaging its economy that already suffered a very hard blow from the eruption.

26/11/2021 20:00h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 69. - LOW PRESSURE ON INFERIOR RESERVATION BUT CLIMBS ON THE TOP AND IN THE EXIT DRIVER. - NEW MOUTH & NECKLACE 18. -

The volcano continues and although in general lines it seems that something low, I do not see it I am very convinced to stop, in fact I think it will take more activity, given the increase in pressure in the main conduct because it is visible an inflation in LP03 and n I'm going to be a only the fact of today where it goes up 2 cm, but it's been several days, that means the contribution of lava is obvious....

This increase in pressure is reflected in the opening of new mouths like yesterday, which would not be rare that it had reactivation, it came out under a house no less, if this happens on the day of the eruption the house would have flown in the air.... there was a lot of luck.

However, vibrations are noticed in the valley and the seismicity looks much more severe than other days not only in the data but in the spectrum, with a swarm yesterday around midnight that has been different from everything we have had, the sign l is different and not very well that it is, because it is almost a spasmodic tremor but very shallow and after a couple of freatomagmatic explosions at 02:20h, you see a noise in all frequencies after which the system stops and calms in s ismicity during hours. Now it's getting power again and earthquakes occur again in both the upper reservoir (10-12km) and the lower (34-37km).

Eruption in La Palma 🌋

The Palmero Volcano now at 19:00 Canaria time continues to expel a lot of lava as we see here and the partner of GEVolcan in La Palma and author of this video from Tajuya.

Cont by Enrique :

Nevertheless, vibrations are noticed in the valley, follow the emission of coladas and ashes, with moments or pulse of more activity and emphasize that the seismicity is seen much more deeper than other days not only in the data, but in the spectrum, after the tea 4.8 of remote last night there was a swamp yesterday between 23 and 24h around midnight which has been different from everything we've had, the signal is different, more than 100 earthquakes on the spectrum and not very well that it is, because it's almost a spasmodic tremor but very shallow. IGN has located only 4 of them.

Then the system has stopped and followed by a couple of freatomagmatic explosions at 02:20h, a noise is seen in all frequencies after which the system stops and calms in seismicity for hours. Now it's getting power again and earthquakes occur again in both the upper reservoir (10-12km) and the lower (34-37km).

Yesterday we had an Earthquake in the deep area, and yet it was not followed by a deep swarm that looks good in the Gomera, but by a swarm on the surface camera. If to this we add that in MAZO, LP06 and LP05 go down (LP05 much for my taste, it seems like an incorrect fact, let's see what they put tomorrow) it indicates a loss of pressure on the deepest levels and would explain that tranquility of the deep sismicity du Rante the day, until now a few hours past noon that it has restarted.
