Another spectacular fire-fountaining episode or paroxysm occurred at the New SE crater during the last night, marking it the 42th such event in 2021 so far.

It came after a significantly longer interval of 4 and a half days since the preceding event on Sunday, but its evolution followed the same pattern observed during nearly all paroxysms this year:
Around 00:40 local time, strombolian activity resumed at the South-East crater, accompanied by quickly rising volcanic tremor amplitude and the source of the tremor having moved to shallow depth beneath the crater itself, indicating the rising magma inside the conduits.
At 01:24, the activity became lava fountains reaching several hundred meters of height and producing a lava overflow on the southern side that traveled SW. The lava fountain lasted until 02:50, after which moment the activity quickly dropped again.
