During the week of November 1 to 7, the temperatures recorded on the edge of the crater of La Fossa on Vulcano show slight growth, and stability on the inner flank.
The flow of CO2 remains continuous and high at the base of the La Fossa cone and in the area of Vulcano Porto.
Access to the Vulcano / La Fossa crater is prohibited, due to the danger of fumaroles and gas concentrations. The carabinieri surprised and strongly verbalized a dozen offenders.

From 8:40 a.m. on November 10 in the morning, what appears to be a new intrusion of deep magmatic material was recorded in La Palma, this activity begins with a seismic train or spasmodic tremor, which lasts about 45 minutes, followed by numerous earthquakes located between 30 and 40 km. This may be due to a reactivation of the deeper reservoir and which could have repercussions on larger inputs of magma to the intermediate reservoir, this would be confirmed if in the coming hours or days the activity of the volcano intensifies, with a more high Strombolian activity, greater release of gas and ash, and increased expulsion of lava.
The Cumbre Vieja lava flows remain stable and their fronts do not undergo movement, except for the flows that reached the sea at Playa de Los Guirres, starting a new lava delta, which merges with the previous one.
The affected area reaches 998.34 ha and maintains a maximum width between flows of 3,100 meters.
As for air quality, there has been an improvement in the five municipalities in the west of La Palma, where yesterday the daily threshold for fine particles was not exceeded in any station on the island. Regarding sulfur dioxide emissions, the values remain low in general, at good or reasonably good levels, with a specific time of regular air quality in Puntagorda. . Regarding seismicity, it shows an increase, during the last hours, at depths greater than 20 km. ; there is an earthquake of 4.9 mblg.

The observatory of the Fuego volcano, OVFGO, reports a weak gray fumarole at a height of 4,400 m above sea level (14,436 feet) which disperses in the west direction of the volcano.
From 6 to 12 explosions per hour are reported, with weak and moderate characteristics that expel. column of ash at a height of 4,400 to 4,800 m above sea level (14,436 feet to 15,748 feet) which is scattered in the west, northeast and north directions of the volcano, weak and moderate rumblings are reported, which cause vibrations in the roofs and windows in the houses near the volcano. Weak, moderate and strong avalanches are observed in the contour of the crater and in the direction of the ravines: Ceniza, Trinidad, Taniluyá, Santa Teresa and Las Lajas, part of the material reaching the edge of the vegetation. A sound similar to that of a locomotive lasting 1 to 2 minutes is reported.
Ash falls are reported to the OVFGO, the Acatenango volcano, Yepocapa and with the probability of ash fall in the communities located north of the Fuego volcano.
