The lava flow from the vent at the southern base of the SE crater is active again this morning, and a new lava flow has been advancing on the surface.
Webcam imagery indicates that this new surface flow started to advance from the vent during the early morning hours.
It is unclear whether it had completely ceased during a brief pause yesterday or whether it’s activity had simply dropped significantly and now increased again, which is suggested by a bulletin of the volcano observatory mentioning that there was a lava flow in the summit area yesterday afternoon.
In alignment with the visual impression of a temporary pause or drop in activity, the volcanic tremor has risen again today as well.
