Ebeko - eruptive activity from 06.02.2022 - from video by Elena Kotenko / via K.Bakanov

Eruptive activity resumed at Ebeko, in the Kuril archipelago on February 6 after a few months of calm.

Following the emission of black cypressoid jets on February 6, 2022, the plume of gas and steam masked this activity from Ebeko to rise straight up.

No notification from KVERT.

 

The flat top of the central cone of the Ebeko volcano, one of the most active in the Kuril Islands, occupies the northern end of the island of Paramushir. Three summit craters lying along a line SSW-NNE form the Ebeko volcano proper, at the northern end of a complex of five volcanic cones.

Eruptive activity was last recorded on November 9, 2021. Gas and steam emissions continued to be visible.

Sabancaya - activity from 31.01 to 06.02.2022 - Doc. I.G.Peru

Sabancaya - activity from 31.01 to 06.02.2022 - Doc. I.G.Peru

The eruptive activity of Sabancaya was maintained, between the end of January and February 6, 2022, at moderate levels, with an average of 25 daily explosions, accompanied by plumes of ash and gas reaching 1,700 meters above the summit.

The I.G.Peru detected 175 earthquakes of volcanic origin, associated with the circulation of magmatic fluids. The VT earthquakes, linked to rock fracturing, occurred mainly in a western sector, with magnitudes up to M2.2.

The deformation monitoring devices did not show any significant anomalies; two thermal anomalies, of max. 13 MW, are associated with the presence of a lava body on the surface of the crater.

The alert level remains at naranja, with a non-accessible zone of 12 km radius around the crater

In the past 24 hours, the Taal Volcanic Network has recorded a low intensity volcanic earthquake and background tremor that has persisted since July 7, 2021.

Activity at the main crater has been dominated by the upwelling of hot volcanic fluids into its lake. which generated 1,200 meter high plumes that drifted southwest and south-southwest.

Sulfur dioxide emissions averaged 7,008 tonnes/day on February 04, 2022. Based on electronic tilt ground deformation parameters, continuous GPS and InSAR monitoring, the island of Taal volcano and the Taal region began to deflate in October 2021.

Note that some measurements (pH, water temperature, inflation) date from 2021.


Alert Level 2 (increased unrest) prevails over Taal Volcano. DOST-PHIVOLCS reminds the public that at Alert Level 2, sudden steam or gas explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas may occur and threaten areas in and around TVI. DOST-PHIVOLCS strongly recommends that entry to Taal Volcano Island, Taal Permanent Danger Zone or PDZ be strictly prohibited, especially around the Main Crater and Daang Kastila Fissure, and extended stays on the taal lake
