Detected several "wide opening" cracks in the main cone of the La Palma volcano

The Geological and Mining Institute of Spain (IGME) reported a few minutes ago that large-opening cracks had been detected in the main cone of the La Palma volcano. This phenomenon is currently being monitored by experts to determine its causes and possible consequences.

The opening of these cracks has arisen after the reactivation of the effusive focus located to the west of the main cone. For now, the lava flows through a volcanic tube, which has several jameos, from which two streams depart that move west on previous streams.

Similarly, yesterday, Saturday at noon, several emission centers associated with east-west fissures to the west of Montaña Cogote were opened, from which several very fluid and degassed flows have started. These flows are moving at high speed to the west, over previously unaffected terrain, currently reaching near the cliff in the Las Hoyas area.

Regarding the intermediate and deep seismicity, it continues at low values ​​and the level of the tremor is between medium and low values ​​with less variability.

05/12/2021 22:00h Canary Islands. - ERUPTION OF PALM ISLAND. - DAY 78. - SCREAMS IN THE VOLCANIC CONE - ASHENSES AND STROMBOLIAN ACTIVITY. - DOWN IN THE SISMICITY. - LAUNCH 21 (SUR) ON THE BORD OF THE CLOTHES AND INFORMATION CUT OFF. -

This thing about the blackout consists of not worrying the staff by putting a blindfold in front of their eyes, and the truth is that they are efficient. I haven't managed to see any video, photo or drone flight showing us the front of the laundry since it was done this morning and from far far away.

However when you see the appearance, some maps come out with eruptive points, coladas and everything else that no one knows where it is published, information needed for the population and civil protection to know what to do. I'm not saying they publish it at the moment, but if after a few hours, as they do with GPS data, better late than never. The only place I find out more or less what's going on is through the IGME viewer where they're putting the coladas.

Yesterday, for example, there were no less than 8 effusive points west of the Cogote Mountain below the cemetery and three of those points were fissures with several mouths, of which is still active the one who is at the least topographic quota feed do la colada 21st colada south that has been roaming the Norias through the South.

Connecting today's post with the previous days, it turns out that the pressurized magma pulse has opened the dique or fracture by which it rises and therefore lava comes out everywhere, and of course, the volcano that is above that dique, also, forming a lord a crack that IGME staff photographed today. This is not new, we were already warning about this process in previous days.

PIROCLASTES AND ASHEN CONE:

In these last few hours you hear more, with more ash emission and above all more strombolian activity in the higher mouths of the volcano, in addition to that it follows the emission of coladas by four different points that I can at least see on the cameras.

TERROR, DEFORMATION, SISMICITY AND GAS:

About the gases, you don't know... they say it's up but we know nothing. I found this on Twitter from Day 3: a nice amount of 2400 tons of CO2 a day and 5202 tons of SO2 a day. A lot of CO2 for my taste and a high SO2 value, lower than the other times, but high, I can't say more and I can't trust more than in a qualitative way the value of these data I've extracted from this link:

https://twitter.com/Filippo60/status/146...6070276104

The tremor is kept high around 20-30 RSAM units, if they are able to load the web that gives them and swings less, possibly because there is no longer water inlet and the hydromagmatic explosions are not seen in the spectrogram like yesterday at the hab I'm up there pressure of the final pipe system, which does not remove that comes with a lot of gas and there is quite a lot of strombolian activity.

The deformation varies little in general, with variations notable and returning to levels of previous days, but in LP03 something rises and moves horizontal, fruit of the arrival of the present magmatic pulse, I am looking forward to seeing what it does m tomorrow well should get to the max and start going down in 1-3 days.

As for the seismicity, when we see the graphics, we have been 3 days without an Earthquake above 4, something that has not happened for a long time, the last a 3.2 and 3.3 in the last hours, it seems to be resurrected in the area of the reservoir above 10 -12 km. and the Energy Rate is decreasing and the total energy accumulated has to be horizontal indicating that the system is relaxing.... that doesn't stop yet, because it has a lot of inertia.

LAVA NECKLACE AND EDITION POINTS

The thing of the coladas already goes from dark chestnut, the riot is total and it catches them in the panties again and again, this last one has been cheeky, the information reports give something with more than 24h delay and the result is more lava than swallowing new homes. Just as we are, with so much material draining and that goes down at full speed by coming out very hot and fluid, all the south area between the coladas of San Juan and the coladas field is found committed, hopefully the natural dique that are the own coladas of the San Juan keep me from going further south.

COLADA 21: It has advanced about 1400m since yesterday and in total about 2500 meters from the point of broadcast, and this in less than 48h, with these impressive data. In the upper area the flow 21 is not very wide between 30 and 50m and 1-1.5m high and does not climb much, but as it goes down, it gets cooler and becomes more viscose and gains in width and height, but loses in speed, with about 100-130m on the Norias area and a height of 2-3m. Since this morning I have no more data, right now I do not know where it is but it seems that it has not gone down the cliff, so it will have developed new arms in the middle area by the road of Todoque and also must be swollen and catching the Tour in the Las area Norias, possibly more than 5m.

COLADA 19: It is the colada that goes north and continues to have sporadic contributions, in view of how the cones are thrown out now, it will surely have a contribution right now and goes through the area of Paraiso down side by the center of the anti coladas field cool.

COLADA 20: It emerged in the southmost part a few days ago and it seems that it has not progressed any further nor has received any new contributions, staying in the top part and standing the front right above the photovoltaic.

COLADAS 22: The new eruptive points in the western area of the volcano more like overflowing of ancient lava tubes that like jameos have overflowed and overturned occasionally, taking the lava to lower areas, where they reappear and that You are very well appreciated in the video This morning's Thermal

Finally highlighting a very fine hot branch that is seen coming down the side to the left of the north coladas, which is observed at the beginning of this warm video this morning that could be a new mouth north of the cone that no one has said nothing. Looking into more detail, the IGME plan resolves the doubt again, it's an overflow from above the wash 19 north of the cone and as seen in the IGME visor.

I finish already, the volcano calms down, all the parameters so indicate, but it still has to finish throwing out the last push or pulse of magma that has reached us from the bottom (LP03 goes up) and opens new mouths and this will take you between 1 and 3 days, then we will see what does it do, if it low pressure and stops or goes back with water inlet or worse yet another pulse of magma comes, a whole unknown. The good thing is that deep in the moment he wants to stop, to see how long it lasts. And let me not forget, I expect a deep 5+ in the next 48h -72h that could come preceded by deep activity prior, we'll see what it does. A lot of spirit. Greetings. (Enrique)
