The explosive-extrusive eruption of Sheveluch continues: on April 23, the KVERT reports an ash plume at 4,000-4,500 meters asl, drifting northeast over 50 km.
Copernicus shows a thinning on the top of the volcano, which allows to see the infra-red signature of ongoing lava flow.
Moderate thermal anomalies are recorded by Mirova, of VRP between 13 and 69 MW.
In Taal, in the Philippine archipelago, the number of volcanic earthquakes is maintained in recent days to about 10 daily episodes.
The Phivolcs recorded for April 20 : 11 episodes, for April 21: 9 episodes, for April 22 : 10 episodes and for April 23 : 9 episodes.
