Regarding the flows of Cumbre Vieja, the technical director of PEVOLCA, Miguel Ángel Morcuende, pointed out that the flow 3 flowed onto the flow 9, to which it joined in waves, until reaching the vicinity of the rating. This flow is the one that causes the most damage and affects buildings, banana plantations and greenhouses in its path.

At noon this Saturday, the lava was about 400 meters from the sea and is being watched, although it is not excluded that it will not reach the water as there is a flat area in which it can spread. . However, if it did reach the sea, it would not be necessary to take any containment measures since this is an area that has already been evacuated.

The lava emission focus on the northwest flank of the main cone provides a flow that moves southwest over previous flows, branching into two arms, one of which juts out west and the other to the southwest. This latest lava flow passes in front of flows 1 and 3, moving over previously unaffected terrain in a southwest direction, advancing 1,500 meters in the last 24 hours, reaching the lower island in the Las region. Hoyas, according to IGN.

Strombolian activity remains intense at 7:30 p.m. (Canary Island time). The fall of volcanic bombs is observed in the vicinity of the cone. In addition, landslides occur due to shock waves from the volcano, rocks are seen at the foot of the small rocky escarpment. (IGME)

Copernicus has updated monitoring of the Cumbre Vieja volcano, whose lava has covered a total of 946.5 hectares since the eruption began on September 19, affecting or destroying 2,532 buildings / constructions so far.

A moderate eruptive activity from the Ebeko volcano, in the northern Kurils, continues. According to visual data from volcanologists in Severo-Kurilsk, an explosion sent ash up to 1.8 km altitude, an ash cloud drifts northeast of the volcano for 5 km

The aviation code has changed from yellow to orange.

Moderate eruptive activity of the volcano continues. Ash explosions up to 6 km (19,700 feet) altitude. could arise at any time. The current activity could affect low-flying planes and Severo-Kurilsk airport.
