Two and a half days after the previous one, the New SE crater produced yet another phase of lava fountaining (paroxysm) yesterday evening 4 June 2021.

It was preceded by a relatively long phase of weak to moderate, but intermittent strombolian activity and fluctuating tremor levels - contrary to most other episodes, the activity had not dropped to low levels after the previous paroxysm, but remained moderate.
The activity increased rapidly after 18:00 local time, then passed to lava fountaining at around 18:20, which generated an ash plume that rose to approx. 6500 meters above sea level and drifted SE.
Like during the previous paroxysms, a lava flow traveled from the rim of the saddle vent area of the New SE crater towards the SW.
The lava fountain ended around 19:30 and activity dropped again sharply. However, the lava flow remained weakly alimented for several hours. By midnight, it had reached an elevation of 2800 m below the Torre del Filosofo area.
