Eruptive activity continues on La Palma
Since the last statement, 34 earthquakes have been located in the area affected by the Cumbre Vieja volcanic reactivation, most of which have been located at depths greater than 30km. Only two of the earthquakes have been felt by the population during this period.

The largest Earthquake has been registered at 05:24 (UTC) today with a magnitude of 4.7 mbLg and has reached a maximum intensity of IV (EMS98) in the epicentral zone.

The tremor signal has suffered a slight decrease in the last hours compared to previous days.

The island's network of permanent GNSS stations continues to show that after reversing the elevation of days 4 and 5 in station LP03, which is the closest to the eruptive centers, it remains at a lower level than previously established. station continues to register deformation towards the south.

In the rest of the stations, the slight deflation possibly related to deep seismicity has moderated.

In view of the calibrated image, a column height of 3,100 masla is estimated at 08:45 UTC. The height of the cone is measured obtaining a value of 1,130 m. above sea level.

The IGN continues its presence on the island, where the CAVE (Center for the Care and Surveillance of Eruption) has been established.

More information on the volcanic activity of the Eruption on La Palma

The IGN will continue to monitor the seismic activity that can be followed through the Earthquake Viewer in the Canary Islands .

The reason is very clear, when lowering the pressure of the magmatic duct system to 500- 1000 meters deep, the underground water that did not enter the pipes due to its excessive pressure, when lowering this, if it enters and generates that the magma accepts more v apor and water and clear, that's fuel for magma, it's like pouring water into burning oil, it makes it much more dangerous and explosive.
Ash rises to 3000m and the latest estimated average data of SO2 is 3250 tons per day, deformation keeps or slightly rises.

In the Gomera sensor there are disturbing signs from a few days ago, the surprising thing is that in the Palma one they don't appear. In the spectrum of the Gomera between 9 and 10 in the morning that I have put you can clearly see several distant spasmodic tremors, I do not know where they are, because in the Palma sensor I do not see them and in the rest neither, but they are almost certainly from the Palma.

Revised update courtesy of Enrique.

16/11/2021 20:30h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 59. - THE UNDERGROUND WATER IS ENTERING TO LOW PRESSURE IN THE VOLCANIC SYSTEM AND THIS RESPONSES WITH MORE EXPLOSIVITY AND ASSH. - GLISSING SIGNAL AND SPASMODIC TREMOR IN THE GOMERA. - That the volcano goes less, does not mean it is less dangerous, it is more resisting with nails and teeth to stop.

The reason is very clear, when lowering the pressure of the magmatic duct system to 500- 1000 meters deep, the underground water that did not enter the pipes due to its excessive pressure, when lowering this, if it enters and generates that the magma accepts more v apor and water and clear, that's fuel for magma, it's like pouring water into burning oil, it makes it much more dangerous and explosive.

EDITED: After reviewing everything, the Gomera signals could go in the same line, it is very clear that water is entering the magmatic pipeline system and that causes an increase in the volcano's explosiveness, and it could even cause a cause earthquakes 1-2km per local overpressures in the last part of the conduit that could reach the surroundings of 3+ or even 4 in the conduit climbing the volcano from the SSE.

Ash rises to 3000m and the latest estimated average data of SO2 is 3250 tons per day, deformation keeps or slightly rises. The seismic energy rate continues to drop to 60 MWh today and has released less than 200 in the last 3 days far from 1000MWh per day of maximum activity or 500 MWh per day of recount a few days ago.

As for lava coladas, first the large column or white steam pen of the entrance of a river or lava laundry that flows over the ancient lavas directly into the Atlantic Ocean (best that can happen, so it does not destroy anything m as) and what After coming down the cliff it reaches the edge of the fajana and wandering over the ancient 8A, it reaches the edge where the water of the sea vapes impressively into the ocean entrance area. The river of lava continues under water as material coming down, it is not believed to stay there and can even generate volcanic tubes underwater, a fact of the most incredible but seen in the 2018 Hawaii eruption. Don't miss this one Drone video:

https://www.youtube.com/watch?v=Ce9VjfwcHbQ
NEW FAJANA AREA: 42 hectares

Today I've had a horrible day and I haven't stayed almost time, not to say that I just deleted this last paragraph, in the end, we repeat, I said I keep thinking that this is over, I give it between a minimum of 6 days and a maximum of 13 days to the view of the data.

At first, the only thing that concerns me is the tremor of the island of Gomera, because there are three possibilities, whether it is 35km or 11km or higher. 35km away would be new magma and longer eruption in time. But I think it is 11 km away for being less intensity than the previous ones and that is part of the last magma injection of the last five earthquakes we had a few days ago and that have caused these signs and that there is still no reached the surface area that it reached in 24-48h, increasing the effusion rate and the amount of lava thrown, which would lower its explosiveness, which has now increased the pressure slightly. Now there is another option more and it is to be produced by the intake of water into the system at lower levels and that it has caused those slipping or whistling by the excessive steam pressure, a bit like a kind of pressure cooker.

The past 48-72h should already start showing evident signs of weakening with decreasing deformation and the pressure that will follow several pulses of high ash when water enters the system again, until from good to first it drops so much the pressure that will cut the supply of lava. And eye once it stops, I don't rule out that I can resurrect a couple of times or more for a few hours until it's definitely gone off.

SO2 should continue to go down, but it could answer something in the next 24-48h with the arrival of this new material if the hypothesis is correct. I'm missing data again, in particular the inclinometers that would warn me about this new magma on the way, so I'm going a little blind. (Enrique)

This statement posted 1 minute ago is so not correct

''The La Palma volcano is "quite" explosive again, as in October

Involcan's spokesman, David Calvo, told Efe on Wednesday that the volcano that erupted on La Palma on September 19 has been "quite" explosive since yesterday, in a situation similar to that of late October.

David Calvo has indicated that during the last hours there has been an upturn in seismicity, so that during the last morning 117 seismic movements have been located on La Palma.

In addition, the tremor, which is the internal noise of the fluids, has increased, so that the eruption "does not look" that it will end in the short term, added the spokesman for the Volcanological Institute of the Canary Islands (Involcan).''

SINCE MIDNIGHT THERE HAVE NOW BEEN 177 EARTHQUAKES.

I just cant understand why they do not confirm facts instead of making their own number up.

The islanders are being pounded at the moment by earthquakes.

The La Palma volcano is "quite" explosive again
The Involcan spokesman indicates that the tremor has increased, so the eruption "does not look like" that it will end in the short term.

EFE11/17/2021 · UPDATED 10:34

Involcan's spokesman , David Calvo, told Efe on Wednesday that the volcano that erupted on La Palma on September 19 has been "quite" explosive since yesterday , in a situation similar to that of late October.

David Calvo has indicated that during the last hours there has been an upturn in seismicity, so that during the last morning 117 seismic movements have been located on La Palma.

In addition, the tremor, which is the internal noise of the fluids, has increased, so that the eruption "does not look" that it will end in the short term, added the spokesperson for the Canary Islands Volcanological Institute (Involcan).

The rise in the tremor indicates that there is greater pressure in the system, and now it is "practically" like the end of October.

The volcano has completed 60 days in eruption and the damage and inconvenience it causes have increased with the arrival of the first rains, which have turned some areas into "mudflats", said David Calvo.

Pevolca update on Thursday, November 17:

➡ The emission of sulfur dioxide associated with the volcano maintains levels similar to those of the previous day, confirming its descending trend. The deformation remains stable.

➡ Intermediate seismicity has recorded an increase in the last few hours, although seen in the long run it can be considered a general downward trend.

➡ Due to air quality, it is likely that access along the southbound coast and evacuated neighborhoods will remain closed all day. Weather forecast tomorrow is expected to contribute to the dispersion of gases and particles in the area.

➡ The Catastrophe notifies 1,467 buildings destroyed by the coladas. Of them, 1,184 are residential use, 154 for agricultural use, 67 for industrial use, 34 for commercial use, 13 for public use and 15 for other use.

New magmatic intrusion with more than 100 seismic events located in what we carry today, especially at intermediate depths and with an earthquake sense of 4.7 mblg at 35 km. depth with intensity IV to SW of Mazo at 07:17 Canary time today Wednesday, November 17, 2021

The tremor is rising again and the diffused gas emissions will surely have risen... GPS LP03 and LP04 closest to the eruptive zone go up again slightly, but they go up... The eruption continues...

REEDITED 14:15 p.m. (17/11/2021):

Two earthquakes of magnitude 4.7 and 4.8 mblg were located today at 12:33 Canaryan time with only a difference of 19 seconds between each other with epicentres to the SW and W of Mazo respectively.

Earthquakes located in La Palma, Canary Islands and its vicinity in the last 15, 30 and 90 days:

Update last night courtesy of Enrique.

17/11/2021 18:45h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 60. - WATER ENTERS THE SYSTEM AND PROVIDES SEISMICITY AND INCREASE TREMURING IN THE VOLCAN. NO MORE INTRODUCTION DEEP MAGMA. NEW NEIGHBORHOOD BORDING TOTOKE MOUNTAIN NORTH. - What do you want me to tell you, I do not square at all the data of the depths of the IGN earthquakes, does not block anything, those that are 10 km away, are much more superficial, that there is no superficial seismicity in the drive and next to the volcano is rare imo and anomal him and those who are 35km away are too deep. We're attending in terms of seismicity referring to three processes at different depth.

1. - The first of the processes, is the release of material by the eruptive point that causes a strong seismic signal of tremor by the higher speed of the materials, which bring more gases. This is mostly due to the presence of more water in the magma. The signal has been going up all day and eye, the volcano is changing its behavior and could suddenly stop, like the Etna does and then start back up for a while or hours. In the upper three chimneys, it is observed that blue smoke comes out with quite SO2 at the bottom, a lot of white smoke with water vapor in the center and that in addition a precipitation form of yellow colored sulfur, indicating the presence of that water and the from above expelled a lot of ash, in this video you look very good:

https://twitter.com/i/status/1461022726752198660

The water entry into the system in the last stretches is more than obvious and perfectly appreciated not only in the emissions of pyroclasts and ash, but also in the fact that deformation does not rise, while the tremor does. The one who is not located seismicity in this area between 1 and 5 km as I say is very rare. Inclinometers should also give a tendency to deflate, in case anyone sees them.

2. - The second of the processes is at the base of the island and the ocean bark between 6 and 10km and consists of cycles of presurization-depressurization in that area that is causing a lot of seismicity and may even water entry, as going down the pressure of the system, in addition to entering pressurized water, some fractures will be closed, but as the system has enough energy or pressure, in a moment it opens them again with an earthquake, so that as soon as it pressurizes a little it breaks and opens again pro calling quite a seismicity in that area. Today we have had a busy day on the island for this reason with earthquakes between 3 and 4 as we predicted yesterday with a maximum of 3.7-3.8, except the bigger ones that are for something else.

3. - Great deep earthquakes have been few, they continue to meet the patterns of approximately 6, 12, and multiple. This process is the most respect imposes me, since it imposes the engine or the pump that feeds the entire volcanic system and there are no spasmodic tremors, so now if it is seismicity caused by the litoestatic adjustments between the pre Zion of the island and the magma, let's the magma no longer push with desire, but the balloon deflates and later in the afternoon gives stronger earthquakes of up to 4.8.

That we have two earthquakes is a very normal measurement error and I think it is due to an anomaly of the natural variation of densities in the bark that doubles the signal (on one side it is more dense and comes before and on the other less dense and comes later) since it is very rare that it happens almost always with the same delay.

EXPLANATION OF WHAT IS HAPPENING.

Explaining this is not easy, in the end the eruption is like a giant hydraulic cat, first lifts the island putting magma very deep warm and less density that enters by a small conduction in one or several "sill" or horizontal dique to about 10 km that extends sideways to along a lot of surface and pushes the island up (deformation up in much extension) then look for an exit or eruptive point (more deformation in localized areas LP03 and LP04) and continue adding material while eruption lasts, h until this is over and stops uploading from lower levels. Then the island tries to recover its initial position by dishing out and coming down again, feeding the eruptive point with this reservoir/s of material of the "sill" or horizontal dique which is what it is doing now, provoking seismicity there, p Ero never reaches its original position, it's going higher as part of the material cools down there, and only comes out between 10 and 20% of the material that enters under the island, the rest stays under the island, and in this way, it is slowly rising with the years. The cushioned sinks of the ravine of the Angustias that drains the Taburiente boiler formed below the sea level and now they are very high, this is the reason they have risen.

NECKLACE MAP:

As for the coladas I've posted a photo marking the coladas heading north of Mount Todoque, the day before yesterday we had one that stopped between 9A and 9C... yesterday there was a small attempt next to the mountain of todoque by the edge, but it stopped and today it has finally exploded and low by the north flanco of the mountain following the south edge of the 9A laundry, let's see if I put a map. In the next video you can see this much better at sunset and it already passes from the mountain of Todoque, inculcán calculated that was going at about 70 meters per hour, a burrada in terms of speed, it travels 1500m in 24h.

Although it does not seem like it, the volcano goes out, it is in the last, it has no deep contributions, the volcano is holding on to the revenues of the material left in the reservoir about 10-12km and when the pressure low enough, the flow d will be cut off and material and stop. Follow my forecast to stop between 5-12 days.. I'll just leave this right here. Now that's it when it stops, we'll see how many storks it will give... hopefully few a couple as much as a few hours.

La Palma volcano eruption update: eruptive and seismic activity increase
Wed, 17 Nov 2021, 19:31

After almost 2 months of continuous eruption, there are no signs it might end soon. On the contrary, the activity - both external and internal (seismic) - has continued to intensify today again, with strong ash emissions during extended phases and more surface lava flows near the vent as well as downslope. Volcanic tremor has been increasing, suggesting that the rate of magma flowing towards and erupting at the surface also has become higher again.
This new surge of lava reactivated the flow front that stalled between Montaña Todoque and La Laguna. Other flows are active on top of the lava field near the vents, while the bulk of lava seems to be reaching and increasing the new combined lava delta at the coast.

How big is the emission of sulfur dioxide (SO2) into the atmosphere due to the current eruption process in Cumbre Vieja?
Research conducted by scientists from the Volcanological Institute of Canary Islands (INVOLCAN) and the University of Manchester (UK) reflect that the amount of sulfur dioxide (SO2) that has emitted to the atmosphere the eruption of the Summit Old 2021, during its first 59 days, it is practically similar to the amount of sulfur dioxide (SO2) generated by human or anthropogenic pollution emitted to the atmosphere by the 28 member states of the European Union during the year 2019.
On the other hand, if we compare these broadcast data for the same time period (59 days), the amount of sulfur dioxide (SO2) emitted by the volcano is 7 times higher than that emitted by the 28 European Union member states during the year 2019.

Record number of earthquakes in one day on La Palma since the eruption began
The Island has registered 249 earthquakes, close to the record of 270 that were registered on October 24
- The eruption of La Palma mutates again and there are more earthquakes, ash and toxic gases

La Palma has registered 300 earthquakes this Wednesday after two weeks in which the number of earthquakes was below 100 per day, with which, without finishing the day (10.00 pm), it already exceeds the maximum observed in the two months of eruption , which was established on October 24.

This rebound occurs when, for several days, there has been a downward trend in various indicators of the volcano's activity, including seismicity.

In fact, the total number of daily earthquakes had fallen below the 200 mark since October 28 and had been below a hundred for almost a week (since November 11).

The maximum earthquakes of this entire volcanic crisis occurred days before the eruption began, on September 14, with more than 300.

At that time, a third of the movements had magnitude less than 2, while the rest were located at values ​​of 2 to 3.

This Thursday, two thirds of the earthquakes are in magnitudes of 2 to 3 and the remaining third, from 3 to 4, with an Earthquake above 4.

The different scientific bodies that monitor the eruption are collecting different data to find out if what happened this Thursday is a specific rebound or announces a change in dynamics in the volcano, after days of apparent downward activity.
