Volcanic activity in Canary Islands 2021

[jand]

OT the islands near Sicily have been put on yellow alert as a dormant Volcano for the past 133 has suddenly started emitting a plume .


''Civil protection: yellow alert for the volcano of the island of Vulcano
Strengthen monitoring and surveillance activities

Passing alert YELLOW Vulcano
The Civil Protection Department has ordered the transition to the "yellow" alert level for the island of Vulcano.

In agreement with the civil protection structure of the Sicilian Region and with the unanimous opinion of the Commission for the prediction and prevention of major risks, the Department has assessed that the significant variations of various parameters of volcanic monitoring, detected in recent weeks by the National Institute of Geophysics and Volcanology-INGV and the Institute for Electromagnetic Detection of the Environment CNR-IREA, require some additional measures and initiatives for risk management on the island.

In particular, the "yellow" alert level determines, among other things, the strengthening of volcanic monitoring and surveillance activities (also with the possible involvement of other centers of expertise in addition to INGV and CNR-IREA which ordinarily deal with it ), a constant information link between the scientific community and the other components and operational structures of the National Civil Protection Service, the updating of civil protection plans, a widespread information activity to the resident population on the island and to tourists, with specific reference to raising the level of risk. The civil protection structures of the Sicilian Regional Authority and the Municipality of Lipari have already been activated in this sense to take all the necessary initiatives.

"Thanks to the efficient integration of the scientific community into the civil protection system, today we can count on volcanic monitoring and surveillance systems that allow us to closely follow the evolution of the activity of our active volcanoes", says Fabrizio Curcio, Head of the Department of Civil Protection. “And that's what we're doing on Vulcan. With the "yellow" alert level (which can be followed by orange and red or the return to the ordinary "green" level) it is very important that there is full awareness of the risk, without alarmism, but with great responsibility. "

The island of Vulcano already ordinarily presents a widespread situation of risk for the population connected above all to fumaroles rich in gas and with high temperatures, but at this stage it must be remembered that they can intensify and extend over larger areas and therefore the danger is greater.

Any further significant changes in the situation will be promptly communicated.''

''01/10/2021 h Canary Islands.- LA PALMA ISLAND ERUPTION.- THE ENJOY-VOLCANICO SISMO-ADVANCE, PRESURIZE AND THE EARTHQUAKES ARE EVERY TIME STRONGER.- This second magma intrusion about 10 km deep that is occurring under the volcano of Old Summit in the Palm, attempts to make way toward the surface by breaking the rock in depth by pressing and pressing the rock, so that it ′′ crushes ′′ as a plank that bends before departing. The rock does the same thing and when part, the ′′ crack ′′ is the fattest and is a broken Earthquake, after which the system loses pressure and the magma advances generating less seismicity if it finds no resistance. I leave you the last 5 located.

Therefore, after a broken Earthquake, (rock) we have a time or time where seismicity goes down, when depressurizing, and there are weak signs of depressurizing fluids (such as those that were located when the volcano a few days ago) until pressurized again, the moment seismicity repounded and earthquakes begin to rise in intensity. As you get closer to the surface, the magnitude is often raised and more noticeable to be more superficial.

With the noise of the volcano, the tremor, small earthquakes are very hard to ′′ hear ′′ by seismographers and can't be located unless you have special seismic arrays-like devices, which allow more Events to be located. I know there are some installed, both by IGN and Involcan. These small earthquakes are the most interesting in volcanoes because they give us very accurate information about what is happening inside the volcano.

With all this, seismicity will follow and as it goes up, we will see if it follows the same path as the first intrusion or choose another path, so we must be very aware of seismicity and deformation, which will indicate us as progress all that magma that's on the way to the surface.

Finally comment on the graphic of released seismic energy accumulated or cantor function, also known as the devil's staircase and we see how it starts to get more inclined or uphill, indicating that the system emits more energy or is entering a release phase of more energy. (Enrique).

EDITED: There was just a 2.8 to 39 km Earthquake, I guess they'll check it out as this wouldn't indicate anything good, rather, clearing your throat to send even more magma upwards... let's go see what they put in the review.. (Enrique)

The magma eliminates the prestigious surfing area of ​​Guirres
It is an area recognized and enjoyed by many surfers ", lamented the Spanish Federation of this sport


Upon reaching the sea, the magma from the erupting volcano on the Spanish island of La Palma has eliminated "any vestige of the Guirres area , an area recognized and enjoyed by many surfers," lamented the Spanish Federation of this sport.

"The 29th will be remembered as a sad day because we are witnessing the disappearance of a natural sports facility that brought so many benefits to the surfing community , " the agency said in a statement.

The president of the Canarian Federation, Ángel Lobo, specifies in the note that the Guirres area "had a great quality of waves, with multiple peaks" and speaks of it as "a magical place."

In the five championships that were held in it, he adds, "things were lived that were not experienced in others", with the local society turned "to enjoy and live" the tests.

Aníbal Pino, president of the local surf club 'Revolcón', shares his sadness at an event that "has totally convulsed" the work of his sports entity.

"The landscape has been transformed and what we are experiencing is hell," he said.

The lava expelled by the volcano has reclaimed 367.3 hectares from the sea, according to the latest satellite calculations
