Lava fountain and ash plume rising from the crater at La Palma volcano during the afternoon of 4 Oct 2021
At the growing cone, activity remained intense. The summit vents seem to have more or less merged to one main vent in the central depression of the cone, probably as a consequence of the partial collapse yesterday, and were producing a pulsating lava fountain. The fountains were still tall, but slightly less vigorous and more pulsating in nature compared to previous days.

The lower vents at the cone, including the separated effusive vent north of the cone, were no longer seen to be as active as before or even stopped. Visible lava flow activity on the slopes of the cone was nearly absent and further downslope seemed to have decreased.
From around 9 p.m., the lava fountaining activity shifted towards more intermittent pulses along with large gas/lava bubble explosions generating shock waves, and ejecting lava bombs in circular directions from the crater, probably reaching distances of 1 km or more, including areas where scientific and security workers routinely need to go. Fog prevented detailed observations after around 10 p.m., but strong explosion sounds could be heard from many kilometers distance.

Strong lava fountaining and effusion of lava flows continue at similarly high levels as during the past days, along with the generation of an ash plume that rises approx. 2 km and drifts southeast. ... Read all
