La Palma / Cumbre Vieja - Panoramic photos of the volcanic eruption, taken during the scientific flight carried out on Monday by InVolcan teams in the Civil Guard helicopter
Fifty days after its onset, Strombolian eruptive activity continues at CumbreVieja on La Palma.
Lava flows are stable, without new surface invasion.
The affected area is estimated at 984 ha.
La Palma / Cumbre Vieja - Thermography of the casting field taken on 08.11.2021 by INVOLCAN staff from the helicopter of the Civil Guard Helicopter Unit. The active flow can be observed from the eruptive cone and its much wider front at the height perhaps of Pedregal, before the area between the mountains of Todoque and La Laguna.

The chemical composition of the plume reflects that the magmatic input is more superficial. This means that the deeper part has less ability to fuel the rash.
There is a downward trend in certain parameters associated with seismicity, tremor or gas emission from the plume.
Seismicity is concentrated in areas of average depth, between 10 and 15 kilometers. An earthquake of ML4.2 (provisional data) and a depth of 12 km was recorded on November 9 at 01:33 local time.
Air quality is good throughout most of the island. The alert is maintained in Puntagorda due to the concentration of gas and in El Paso, Los Llanos de Aridane, Tazacorte and Tijarafe due to the high concentration of small particles. In particulate affected areas, it is recommended to use an FFP2 mask and stay indoors, especially if you have a weakened immune system.

In the past 24 hours, the Taal Volcano network recorded 111 volcanic earthquakes, including 26 volcanic earthquakes lasting 1-2 minutes, 85 low-frequency volcanic earthquakes, and one earthquake of low level which has persisted since July 7, 2021.
The activity of the main crater was dominated by the rise of hot volcanic fluids in its lake which generated a plume of 1,500 meters high which drifted towards the southwest.
Sulfur dioxide (SO2) emissions were on average 11,435 tonnes / day on November 8, 2021.
Based on soil deformation parameters from electronic tilt, continuous monitoring by GPS and InSAR, Taal Volcano Island began to swell in August 2021 as the Taal region continues to undergo expansion. very slow. since 2020.
Alert level 2 (increased unrest) prevails over the Taal volcano. DOST-PHIVOLCS reminds the public that at Alert Level 2, sudden explosions of steam or gas, volcanic earthquakes, minor ash falls and fatal accumulations or expulsions of volcanic gas can occur and threaten areas in and around TVI.
The eruptive activity of Sabancaya, in Peru, remained at moderate levels between November 2 and 7, 2021, with an average of 64 daily explosions, accompanied by plumes of gas and ash reaching 2,500 meters above the summit.
During this period, the I.G.P. detected and analyzed 817 earthquakes of volcanic origin associated with the circulation of internal fluids; VT earthquakes, linked to the fracturing of rocks, occur as usual north of the volcano, of magnitude 2.0 to 3.6.
There are no significant deformation anomalies; Eleven thermal anomalies were identified by Mirova, with a maximum value of 30 MW.
The volcanic alert remains in Naranja, with an inaccessible area of 12 km.

Over the past 24 hours, several ash emissions have been observed at the Reventador, heading west and south-southwest, heights approaching 800 and 1000 meters above crater level.
The Washington VAAC reported 5 alerts of emissions observed in satellites, directions varied between west, northwest and southwest and heights did not exceed 1,000 meters above crater level.
The MIROVA system has reported 1 low thermal alert to the Reventador in the last 24 hours.
Over the past 24 hours, most of the time the volcano has appeared clear, observing the emissions already described. Incandescence was observed in the crater at night
Seismicity is characterized by: 79 explosion earthquakes, 56 LP earthquakes, one emission tremor episode, and one harmonic tremor episode.
