The effusive and explosive activity continue at elevated levels. During the night and this morning, frequent lava surges have occurred at the crater.
Large amounts of lava can be seen flowing out in surges from the breached crater, covering the lower northwestern flanks of the cone with sheet-like flows.
These lava flood events are likely caused by partial collapses at or around the lower vent in particular: it can be seen producing constant, pulsating, voluminous lava fountains, while degassed lava flows out from its base. This activity leads to constant changes in morphology of the crater area by rapid accumulation of material in the vicinity of the vents; the newly formed structures at times becomes too steep or otherwise unstable, then collapses. When this happens, larger amounts of lava that had been confined behind temporary dams can escape quickly, causing the observed surges.
