The south of La Palma registers more than 120 earthquakes in 24 hours
The most intense, 3.9 degrees, was registered early today

The southern area of ​​the island of La Palma, where the volcano eruption is located, has registered more than 120 earthquakes in the last 24 hours since this Monday, of which 12 were felt by the population.

The highest magnitude on Monday was 3.7 degrees, a record that was surpassed this Tuesday with another Earthquake registered in Villa de Mazo of 3.9 degrees at a depth of 11 kilometers.

Likewise, of the total number of earthquakes, six have occurred at great depth, between 30 and 36 kilometers, according to the National Geographic Institute.

Volcanic tremor pulses have also been produced as activity intensified and the column height was 4,500 meters.

The Volcanological Institute of the Canary Islands (Involcan) estimates that the amount of sulfur dioxide (SO2) emitted by the volcano on the Spanish island of La Palma since it erupted on September 19 amounts to about 250,000 tons.

This calculation, Involcan pointed out in social networks, can be considered "an underestimated value" since it is based on the realization of SO2 emission measurements in land mobile position, which currently have "important limitations due to several factors."

Mike Hayward comments I think the deleted EQ he mentioned is the M4.7 that was wrote about in the paper I posted this earlier.


It's hours ago it seems like it has bothered and they deleted it:

Good morning to tod@s.Destacar great seismicity either low frequency or greater than two we continue with the great swarm yesterday that we added a couple of them magnitude 3 or almost 4, so we appreciate it on spectrums is what I'm nominating an unstable area. Whatever wants to get out is on the way we started as we started before it erupted for the first time they want to or won't go up. A particular movement we have it removed from the area of the swarm one of magnitude above the rest most south of the iron that then relocate it between 11 and 7 km deep in fuencaliente there is a delicate situation and the authorities without even give or an explanation for not giving them ask me my people there, because no one notice that seismic activity would be increasing any of the authorities, because it is not that it will increase will go to more unfortunately and people should have instructions to do in case of moves BEFORE DURING AND AFTER magnitude 4 produced by that magma approaching the surface. It seems disrespectful to me what you are doing according to the BOE you have an obligation to give real and truthful information can not be played with the lives of people, you have to explain but for them to understand not to generate more doubts, so no would have to turn to sources that are not you shame I feel that if air quality is good and quadruple the values allowed to be harmful to health, if everything is normal I feel to say that if it will be a normal situation if before an eruption is normal. But it's normal where it's known to be being made to say if there's another possibility of eruption, nature is unpredictable, rather NATURE is warning that something is coming and ignoring those signs you might have a serious problem. The magmatic camera keeps filling up and makes it look at a movement of 3.9 to 34 km deep, it's time to make a right decision before the volcano talks more day by day alone saying everything is normal, when you are have spent hours and hours on the ground moving during the early morning just telling you something that volcano goes 7 steps ahead of them I just have to thank those emergency responders for being there always and not knowing what's really there..

We continue with yesterday's great swarm hybrid VT movements and low frequency, swarm again with each other just know that there are no catastrophes there are bad decisions (MIK3)

This the M4.7 Mike mentioned was deleted by IGN.


The IGN detects an Earthquake in the south of the Canary Islands of magnitude 4.7, according to the provisional calculation
The depth of the Earthquake has been 5 kilometers

The National Geographic Institute (IGN) detected at 8:57 p.m. an Earthquake of magnitude 4.7 on the mbLg scale in the south of the Canary Islands, although it points out that it is a provisional calculation.

The depth of the Earthquake has been 5 kilometers.

THE PALM
The 'seismic swarm' in the south of La Palma has once again increased its activity with more than 40 earthquakes last night - from 8:00 p.m. on Sunday - in the municipalities of Fuencaliente and Mazo, near the southern part of the island.

In general, earthquakes are still maintained at high depths that fluctuate between 7 and 14 kilometers and with magnitudes that oscillate between 2.3 and 3.7 on the Richter Scale, and several of them have been felt by the population.

Inés Galindo: "At the moment it does not seem to have to end and there is a risk that the fracture will spread to the northwest"
You sent
At last someone else another geologist speaks up.

New leaks continue to worry, and the possibility of them reaching saved buildings. The lava delta already covers 32 hectares, with a growth of two hectares in a single day. The ash completely covers the streets and furniture of evicted towns, such as Puerto Naos. More than a thousand buildings have already been affected by the lava, with a total of 430 rescued. We talked to the volcanologist at the Geological and Mining Institute, Inés Galindo.

Detected a new fissure 100 meters from the main cone of the La Palma volcano, although without an eruptive character
The data on seismicity, geochemistry and deformation suggest that "the end of the eruption is not near", that it is in the "mature" phase, so that we must prepare "to spend many days", the experts have reported after the committee. of scientists from the Canary Islands Volcanic Emergency Plan (Pevolca)
- The wash is already over a kilometer wide in some sections


The director in the Canary Islands of the National Geographic Institute (IGN), María José Blanco, revealed this Tuesday, during the press conference after the scientific committee of the Canary Islands Volcanic Emergency Plan (Pevolca), that experts have detected the opening of a fissure area about 100 meters northeast of the main cone of the volcano with emission of gases and high temperature soil that, in principle, has no eruptive character.

Likewise, he explained that the seismicity, geochemistry and deformation data suggest that the end of the eruption of the La Palma volcano, which is in the "mature" phase, is not near, so that we must prepare "to spend many days" , has stated.

He has also indicated that the Weather forecast indicates that this Wednesday afternoon the winds will turn the column of ash and gases from the plume towards the northeast slope of the island, which could affect the operation of the La Palma airport.

For his part, the technical director of Pevolca, Miguel Ángel Morcuende, has reported that so far the wash has destroyed 726 buildings, of which 605 are homes; 58, buildings for agricultural use, and 30, for industrial use, according to the Cadastre data registered until the afternoon of this Monday.

Morcuende explained that these figures differ from those recorded by the Copernicus satellite, since it detects any point that may be a building, which is misleading "because in the end it may be a pergola, a precarious chicken coop, an abandoned haystack, among other constructions ".

Specifically, the latest data provided by Copernicus speak of 1,154 buildings affected by the eruption, of which 1,046 would have been destroyed by lava and 108 would be damaged or at risk of collapse.

The flow affects 6.74 hectares more than in the previous day
The latest measurements point to 420 hectares affected by the lava, an increase of 6.74 compared to the day before, in a perimeter of 36.24 kilometers and a maximum width of 1,250 meters.

The lava delta that has entered the sea for now occupies an area of ​​more than 36 hectares and has advanced 540 meters from the coastline.

The air quality on the island has improved compared to previous days thanks to the entry of trade winds. While the marine plume of water vapor and hydrochloric acid that occurs in the contact of the lava with the sea remains in a reduced area near the delta.

Seismicity is increasing in terms of number of episodes and magnitude, and it has also been more felt by the population, especially in Fuencaliente and Villa de Mazo, but it remains at average depths of ten or more kilometers.

Daily sulfur dioxide emissions were 1,200 tons on Monday, with a cumulative 250,000 tons since the eruption began, and the volume of magma expelled could be at 45 million cubic meters.

A "safe" island for visitors
So far, the Fuencaliente hotel has housed 209 people of the approximately 6,000 evacuees and 553 people work in the emergency operation, explained Morcuende, who has insisted that La Palma is a safe island for all visitors and that only on 8 % of its surface is affected by the volcano.

Latest update courtesy of Enrique.

05/10/2021-19:00 h Canary Islands.- LA PALMA ISLAND ERUPTION.- SEEMS LIKE THE SISMICITY IS CALMED, BUT THERE ARE MANY FEARS AND NOISE.- It's too early to be sure but lots of vibrations are being noticed in the plains area in houses with crunching doors and continuous windows and a noise like a river under their feet. But what catches my eye is that two sources of noise are noticed, one in the volcano emission zone and one underground to the south.

It's really not reassuring at all. If there is no more strong seismicity than I hope in the next few hours with an event in the 4 environment would mean that the system of the Earthquake-volcanic swarm is coming to its maximum and could have broken or broken in the next couple hours, which it would mean that magma would make its way to the surface, either through the existing eruptive canal or a new one, I don't know, it's too soon.

What if I know, when I break up, it will start climbing from the 10 km and would be like an elephant in a cacharía for the noise it will make and should cause seismicity as it ascends, so the earthquakes hanger less than 3 km from now on are vital to know where it's going.

For making a comparison, this is like a plank we put a weight on, and at a point it starts crunching... CRA CRA CRA that would be the earthquakes of the swarm.... but there comes a time that breaks into a sound CRACK ′′ and yields, that's the shooting Earthquake and the moment the rock lets go the magma on its way to the surface. That point is near, otherwise it has already occurred in some of the earthquakes we carry, but I do not see earthquakes that would be the ultimate sign.

For making another comparison, an eruption at the end is like when a reservoir bursts... first a crack is made little by little, but it gets more powerful as the exhaust gets bigger and eventually ends with a red, in this case of magma. I hope he does it for the existing eruptive point channel and not for a new one.

Now you have to monitor the hier earthquakes and deformation, the next 24-48-72 h will be intense to truth, we'll see what happens in the end, hope it doesn't hurt much more and it's over..

As for flow, I have already been able to update the map, I have been working on two days to see where the flow of the eruption move and the good news is that both North and South are standing and not threatening new structures, except we have an overflow of the laavic canal, as has already happened in some places with small overflows. I'm giving you more details in some answers. (Enrique)
