Volcanic activity in Canary Islands 2023
#61
12/04/2023 - 19:30h Canary Islands. - WE CONTINUE WITH THE CUT OF INFORMATION OR NO INFORMATION WITH EARTHQUAKES HAPPENING IN THE ARCHIPELAGUE, ONLY LOCATED ONE OF 2.3, THE REST.... NOTHING AT THE MOMENT - Maybe when they review publish something, at the moment nothing at all, and it is that the IGN is spending it so, when alert and talk much about the subject, remove iron omit data, which do not put live, usually do so deferred after days or weeks, so that they comply, nothing happens and the staff doesn't find out what's going on...... In the absence of one, several active volcanoes, one of the 10 most dangerous on the planet in Tenerife, whoever doesn't want to see it, it's up to you. This isn't alarming, it's reporting.

That's why today I bring you an interesting document, the complete (volcanic) risk assessment plan of Tenerife and in force which is from 2021 and all the associated scientific information that is a lot. I made a couple of figures. That has quite a few shortcomings and improvements, we have to roll it a lot more if we don't want to have a disaster in case of a big eruption.

ISLAND ACTION PLAN FACING VOLCANIC RISK

CHAPTER 3. RISK ASSESSMENT

https://transparencia.tenerife.es/archiv...InZryKHe2M

The truth is that there are many documents on the issue, I find it interesting this one from 2010 that talks about a possible explosive eruption of the White Mountain type, an eruption that could require even the evacuation of almost the entire island of Tenerife, unthinkable thing, as where it can lead to so many people. In Italy it has taken them 20 years to make a Vesubian plan to evacuate 5 million people, in the Canary Islands there is practically nothing.

6. Dangers associated with Tenerife eruptions

its impact and reduction in case of a
future eruption

https://www.iehcan.com/wp-content/upload...OUxX0xQIyY

And of the history of the volcano, it has had not an explosive eruption, but several, and the latter was not exactly that of the White Mountain, but that of Teide that the Guanches tell in their legend of Guayota about 1240 years ago was very explosive with 3 days of darkness sunless and Burst Mountain 990 years ago which was also moderately explosive.

Historical eruptions have generally been basaltic like that of Palma, more "soft" or smaller and which would be the most expected in case of an eruption.
In the following document, all this is broken down in more detail and the number of eruptions, more than 50, draw attention, getting bigger the more time has passed, as time erases the traces of the smallest ones.

La Palma is still moving, with a remarkable event locating today, although it hasn't been the only one.

In the curve of the seismic energies released accumulated in the Palma, a tipping point is perfectly observed since mid-February where it practically triples or quadruples the rate of energy release and has since then remained upward indicating a new process, possibly migration towards the south of magma under the island with a small pressurization under the dorsal, today at 15km in the summit area and which seemed to be moving south and has now stopped and is giving seismic Events in its perimeter. If it is a small intrusion at that point from below, (the deformation does not indicate) the serious problem is that the volcano would be rearranging again, I hope not, but it is one more possibility that we will have to watch.

695. - 16/04/2023 - 22:15h Canary Islands. - SMALL SWAMMERS IN TENERIFE, A LITTLE ACTIVITY IN THE PALM AND SOME TECTONIC Earthquake BECAUSE OF REGIONAL TENSIONS. - The activity in Tenerife continues with its movement, today we start with several localized earthquakes and several more not localized in the interior of Tenerife, some of them in the area of the magma reservoir under the Ucanca boiler at about 11-15 km deep. Day before yesterday 1 located, yesterday 2 located and today 3 located. It's several swarms of half a dozen or more Events from which only a few have been located.

Point out that yesterday's swarm at around 3 am in the morning is very similar to today's at 9 am. Both are volcanic and both look like LPs indicating fluid movement, in fact today's is followed by a small episode of harmonic tremor due to depressurization of gases about 4-5 minutes after the main event.

Something may have been noticed in some areas of the island, these seismic trains of various tremors can be felt very weakly in certain areas by producing resonating such as wood crumbs or noises. Keep an eye out for this boiler activity in the next few days.

As news, this week in the Guayota Report, the smoke temperature is quite high, about 94oC, I don't remember seeing it higher than 92-93oC..... what I find curious about. In a little video at the top of the Teide, that sent me
Joseph Manuel Lugo a while ago you can hear a small PUFF from the fumes at 13:15h today in the Teide, either there's a pulse or more gas comes out or hotter... I don't know, let's see what they tell us in the next few days. I've put it in the replies if you want to see it.

https://www.involcan.org/.../GUAYOTA/gua...-es-co.pdf

And emphasize in this report, that where the IGN has located about 6 earthquakes, Involcan has located several dozens in the Cauldron area, more than 30, wins by hitting the IGN, or what is the same, something smells strange and is not precisely the volcano, but in the IGN. Looking forward to seeing the next Guayota weekly report. Such a shame that monthly reports are not updated since November 2021 with a total of almost 5 full years. Here's the link in case you want to read it...


On the other hand there have been several earthquakes in the areas surrounding the island quite deep, highlighting one of them of 2.2 magnitude and quite deep near the coast of the Acentejo Massacre in Northern Tenerife.

Then something has also moved in the area of the Enmedio volcano, (the depth is from the bottom, the surface of the ground not from zero cota..... otherwise it would be in the middle of the ocean).

es2023hkvlc 16/04/2023 12:23:36 27.8586 -14.9060 8.0km M 2.9 mbLg ATLANTIC-Canary Islands

Ultimately more tensions with two earthquakes around Palma, one of Magnitude 2.9 to the NW at 30 km and another of magnitude 2.5 to 17 km to the SE.

LA PALMA: The past 14th we had a small peak activity in the summit area southbound at about 10-11 km deep with a couple of earthquakes, adding to others more in previous days giving a swarm, indicating that magma at that point is suffering from increasing pressures, either by regional tensions, which seems to me the most logical and has pressurized a bit than by another process as a new intrusion from the depth, which almost ruled out by the absence of deep seismicity and GPS sensors have not even moved. There is a lot of regional tensions.

Little more to add to all this, we have volcanic activity in which there are more questions than answers, although something if I am clear, La Palma calms down and Tenerife is activated little by little with each passing day, and all you can do is watch, watch and prepare in case one day it starts to move more seriously warning of a possible pre-erutive event. Just basic activity at the moment and climbing each passing day. Nothing else. Greetings. (Enrique)

Every time I think there are more weird things, look at the spectrum and then look that both earthquakes are very close under the Teide, one 7.7 km under the lower part of the cable car and another 2.6 km, under the high area of the cable car, but look at the size on the CCAN seismogram, the second most dark, comes out larger, but oh so so much.. not very credible, both signs should be very similar and not have such a big difference.

When you look at the phases at the CCAN station you see these data, the same magnitude.... and the difference in depth is too small to cause such a difference. But what happens, is that they don't look at the signs of the seismographs or they take us for fools, they are not of the same magnitude, that's Clarisismo:

Whatever it is, just look a little to see that the monitoring system of the IGN is deficient and needs to be updated and improved or better yet, disappear and given such surveillance to another organization such as the IGME or INVOLVED to be in charge of volcanic surveillance in the Canary Islands and do it with more heat and with more data in the open, because the IGN is unfortunate in the face of the public.
