2021 islands canary volcanic activity

Volcanic activity in Canary Islands 2021
The Teneguía turns 50
On October 26, 1971, around 3:30 p.m., an eruptive process began that would last until November 18, in what would be the shortest historical eruption of those recorded on the island.

On this day 50 years ago, the earth shook on La Palma to give way to the Teneguía volcano, in Fuencaliente. On October 26, 1971, around 3:30 p.m., an eruptive process began that would last until November 18 , in what would be the shortest historical eruption of those recorded on the island. The emission centers were located south of the San Antonio volcano, in an unpopulated area.

The volcano debuted with great explosiveness and later showed a more effusive character. The lava reached the sea creating a 29-hectare strip. In total, the volcano expelled some 43 million cubic meters of lava material that covered 276 hectares, compared to the 900 hectares that the current Cumbre Vieja volcano has already invaded, which has expelled 100 million cubic meters of lava and pyroclasts.

Due to the lower magnitude of the volcano, the Teneguía caused the death of two people by inhaling gases; Heriberto Francisco José Felipe Hernández and Juan Acosta Rodríguez.

The ground on La Palma has risen 10 centimeters in the last 24 hours
On the other hand, in the more distant stations a slight deflation is maintained, possibly related to deep seismicity.

The geodesic network of stations installed on La Palma has detected an elevation of more than 10 centimeters in the last 24 hours, and a deformation towards the south in the station closest to the eruptive centers of the La Palma volcano, reported the National Geographic Institute (IGN).

In contrast, a slight deflation is maintained at the most remote stations, possibly related to deep seismicity, notes the IGN.

The amplitude of the volcanic tremor signal is maintained at medium high levels, with intensification pulses.

The dispersion cloud of sulfur dioxide (SO2) reached 2,000 meters in height at 8:00 am on Tuesday.

Regarding seismicity, the IGN has located, since the previous report, 184 earthquakes in the area affected by the volcanic reactivation of Cumbre Vieja, 17 of which have been felt by the population.

Of all the earthquakes located, 80 have a magnitude equal to or greater than 3.0 mbLg.

The Earthquake that occurred at 7.05 am on Tuesday was the largest (4.2) in the period analyzed.

In addition, five earthquakes have been located at depths around 30 kilometers. The rest of the hypocenters of the period are located at a shallower depth, around 12 kilometers.

552 moves from October 24 to October 26 It is clear that seismic activity is migrating, east of the palm. Those detachments occur by low-frequency movements and VT (Volcano-Tectonic) there is an increase in significant deformation surpassing 10 cm in GPS stations LP02 LP03 something pushes and wanting to and not forget that big swarm that swarm swarm With other swarms. Everything goes well and they put this on? That's creating uncertainty for the population. Be careful and be safe, don't forget to always have the KIT pointed greetings (MIK3)

To this energy ladder you have to add today 26 a deformation between 10 cm according to the IGN, 16 cm in the graphic, is more than obvious, normal normal.. is not it.. (Enrique) ,

Latest update courtesy of Enrique.

15:30 26/10/2021 h Canary Islands.- PALM ISLAND ERUPTION.- 50 ANNIVERSARY ERUPTION OF VOLCANO TENEGUIA-UPLOAD THE DEFORMATION, UNDER SOMETHING THE SIMICITY AND SO2 GAS AND TREMOR FOLLOW VERY HIGH.- This rash doesn't end shortly, that's clear, and the deformation so large (16-17 cm on the sensor) (10 cm according to IGN) near the eruptive point and that massive amount of SO2 of 53600 ton / day of the last fact is only fearing that the eruption increased its material emission rate in the next few hours.

Be careful, as the gases are responsible for the death of a fisherman and a photographer in the eruption of the Teneguía that today is just 50 years old... and moved to mode, do not believe, and do not were the strongest..

7114 10:00:00 25/10/1971-17.8500 5.0 VI S Fuencaliente. LP, Palm Island

And today we also have remarkable seismicity with a 4.2 of a swarm that continues to drop seismic energy at an important rate of almost 200 MWh / day.. almost an Earthquake of magnitude 5 a day.

Today is coming down, but we already know that you are saving strength for an older one, as a pass on El Hierro and in previous days, in principle in the swarm has not changed anything, so I do a review of the post 533 about seismic forecast that is keeps it.

′′ With this data I can give a seismic forecast with a 3 hour up-3 hour error down for that next moderate Earthquake that will be noted throughout the archipelago.

TERREQUAKE SISMIC 5 + FOR DAY 10:30 27/10/2021 h IGN, 11:30 h Canary Islands and 12:30 h peninsula."
DEFORMATION AND TREMOR:

The high tremor and clear as a deformation located near the eruptive area so accused, only indicates that the pressure of the magmatic pipe system is very high and that new eruptive points will be opened in the next few hours / days that are going to increase the emission rate to ease that excess pressure. We'll see if these new mouths open to the NNW or SSE or on both sides, about 500 m at the most, occasionally further away, but I don't think it will exceed the kilometer away from the current cone.
