The eruption has been relatively stable during the past 24 hours: sustained, fast-pulsating lava fountains are rising from the vent, reaching several hundred meters and generating an ash and steam column that rises near vertically to estimated 3-4 km elevation.
The fountaining is remarkably stable, although at times briefly interrupted by giant lava bubble explosions that eject glowing lava bombs in all directions to more than 1000 m distance, often showering the whole cone with red-hot lava ejecta.
Some of these produce cannon-shot loud detonations with visible shock waves that are felt in many kilometers distance. Some people confused them with earthquakes.
Volcanic tremor overall is stable and still high, perhaps with a slightly decreasing overall trend. Earthquakes have mostly ceased and inflation seems to have stalled. This indicates that the eruption has likely found a stable phase.
Not much significant activity occurred at the lava flow fronts, which continue to widen the flow field and/or overlap older flows, thus thickening it.
