The new volcano that began to erupt in La Palma on September 19th is now officially the most damaging among the historical eruptions that occurred on the island of La Palma since records began. Until now, the eruption of El Charco in 1712 was the most destructive, affecting 441 hectares of land, but the new one has almost doubled that now, according to Involcan and Carmen Romero, a renowned professor of the University of La Laguna.

According to the latest measurement by the European Copernicus satellite system, carried out at noon on Monday, the flows from the new volcano cover an area of ​​811.8 hectares.

Involcan have made a list of the eight historical eruptions of La Palma and the areas that their respective lava flows affected, as follows:

1). Tacande 1430-1447 (424 hectares)

2). Tehuya 1585 (338 hectares)

3). Tigalate 1646 (296 hectares)

4). San Antonio 1677-1678 (210 hectares)

IGN warns of possible Intensity 6 earthquakes; the maximum has been 5 so far
Category: Isla BonitaCreated on Wednesday, October 20 2021

The current level of seismicity continues to be produced by the eruptive process of La Palma, it continues to indicate that it is possible that more felt earthquakes may occur, being able to reach VI intensities (EMS). This was reported by the scientific spokesperson for Pevolca, María José Blanco, in the usual appearance each day.

In this regard, he pointed out that these temples could cause small landslides in sloping areas.

In addition, he pointed out that seismicity continues to be located, mainly, close to the seismicity of the first days, at depths between 10 and 15 km.

There are also earthquakes located at depths greater than 20 km, which in the last hours continue to have a high magnitude. The high values ​​of the amplitude of the tremor signal are maintained, with intensification pulses.

The maximum magnitude observed was 4.8 mbLg of an event at a depth of 39 km, with intensity V EMS. The high seismicity recorded at intermediate and deep depths is part of the same current eruptive process. No significant surface seismicity is recorded.

Magnitude and intensity are two frequently confused terms and, although it is true they have a close relationship, their meaning is completely different. The magnitude is used to quantify the size of the earthquakes, it measures the energy released during the rupture of a fault, while the intensity is a qualitative description of the effects of the earthquakes, it involves the perception of people as well as the damages material and economic suffered as a result of the event.

Recommendations:

Abroad:

If you are outside and there is an Earthquake, find an open place and stay away from structures that could fall to the road and from areas at risk of collapse. For your safety, remember these self-protection tips:
• Go to open spaces.
• Stay away from buildings, balconies, traffic lights, streetlights, power lines, or trees.
• Do not go near areas with danger of landslides.
• Follow the recommendations of the authorities and find out through official channels and the media.
• If you are in a vehicle, slow down and stop the engine when possible, away from buildings and steep areas. Set the emergency indicators and stay in the vehicle until the Earthquake ends.

Inside:

If you are surprised by an Earthquake inside your home, stay calm and follow these
self-protection tips:
• While the shaking lasts, do not go outside.
• Protect yourself under a door frame or some sturdy piece of furniture, such as a table.
• Do not stand near windows.
• If you have to leave your house, disconnect water, electricity and gas.
• In case of evacuation, go down the stairs and do not use the elevator.
• Follow the recommendations of the authorities and find out through official channels and the media.

The PeVOLCA has ordered the PREVENTIVE EVACUATION of more neighborhoods, this time the ones located south of the urban cap of Tazacorte, this is: Marina, La Countesa, Football Field and, waiting to decide on San Borondon. As confirmed by the mayor of Tazacorte, Juan Miguel Rodriguez, more than 500 people living in these neighborhoods surrounded by banana trees in the area attached to the beginning of the urban shell will be evacuated immediately. The passage of laundry through La Laguna (Los Llanos de Aridane), seems to be unstoppable and will continue to descend, predictably through the northern area of ​​this mountain. Below it is the Football field with a nucleus of annexed housing and the Tazacorte cemetery. #lapalma #newslapalma #earthquakeslapalma #volcanlasmanchas #urgentcaislapalma #emergencypalma #Palma volcano #Palma volcanovolution #PalmaVolcancumbrevieja #affectedpalma #evacuationsestazacorte #evacuationslapalma

20:30 20/10/2021 h Canary Islands.- LA PALMA ISLAND ERUPTION.- MAPS OF THE COLLADES-CONTINUES THE ERUPTION AND BY ENERGY WE DON ' T KNOW WHAT WILL TAKE TO END.- PRONOSTIC OF TERREMOTES The most urgent are the two flows that are already affecting the town of La Laguna, the 10 B flow has moved 200 m from yesterday afternoon and 10 c (the most north ), he's moved double, 400 m.. my mother.

The 10 C flow is the one next to the school, which is still standing, but the lava is already affecting it and the fire station is currently on fire, the 10 C seems to progress less. It's the worst, because if it goes on, it wouldn't go south of La Laguna Mountain, but would go north to San Borondon and Tazacorte, although I don't think it will come as the slope turns and goes to the sea, though Several arms of lava come, that would take away a lot of banana trees.

The last of the 10 B is that it has swallowed the gas station and arriving at the crossing and main street and headed downtown to Church and square and moving forward now it must be about 50-100 meters more about this map. Hope this one, 10 B, keeps turning and heads south of Laguna Mountain as it's there.

But this isn't over and I see the next move, a new arm is forming above the old Football field north of the Polygon, which I called 10 E, as it's the one that was above that has gone walking down the northern edge of previous laundry, which could give a new arm that would move even further north than the 10 C flow, in principle bordering it, hopefully stop... this is horrible..

While the 9 C flow going to the sea has stood very close to the cliff, about 80 m and unless you receive another batch of fresh lava will stay there... we'll see what happens.

THE VOLCAN:

The energy does not go down and continues to rise daily, indicating that it takes inertia and strength, so I do not see it stops in no time, but the lava comes out with less resistance, drains better, so shows the slight drop in deformation and that the tremor holds. I have no more news sorry... we have 2-3 weeks left of eruption at least. and from there to months...

SYSMIC PRONOSTIC: The same phenomenon is occurring as in the swarms of El Hierro, there is not so much intermediate seismicity and isolated earthquakes occur becoming more powerful. The latest major Earthquake sets the pattern for the forecast..

es2021unlnj 22:48:00 19/10/2021 21:48:00-17.8192 39 km M 4.8 mbLg IV-V SW MAZO VILLA. ILP

That leaves us two highs. I start with the last Earthquake.. tonight at 24 pm 50 min later and tomorrow. 37 h 25 min where the strongest Earthquake is most likely.

1.- The first high of 4 + would be at 22:30 h IGN, 23:30 h Canary Islands and 00:25 h peninsula.

2-The second maximum of 4 + would be at 10:55 h IGN, 11:55 h Canary Islands and 12:55 h peninsula.

If you keep it up next is 4 +en the first max and 4.5 + in the second max... we'll see what you do, next on the list if you follow is a 4.9-5.0 I leave it there. Let's see if it stops. (Enrique)
