Activity of Sheveluch, Taal, and Zavodovski island.

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.

A magnitude 6.0 earthquake was recorded on April 22, 2019 at 14:49 UTC, and a depth of 100 km in the South Sandwich Islands, near Zavodovski Island.

This island is constituted by a basaltic stratovolcano, Mount Curry, decentered towards the west; two cracks extend on the eastern flanks and a lava platform is located on the east coast.

Its first eruption was observed in 1819, and the last activity dates from 2016 (30,03,2016 - 16,05,2016)
