The activity of the volcano has been fluctuating between high and medium levels. It is characterized by strombolian explosions from multiple vents in the crater terrace with averages of 22 events per hour during the past day.
Tremor and degassing values are at stable, medium levels.
A friend of ours visited the island during the past week and on 26 observed a short-lived small viscous lava flow in the upper Sciara del Fuoco: after a stronger explosion from the western vent, two effusive vents opened in the outer flank of the crater and continuously fed a viscous lava flow, which reached about 50 m length and generated abundant incandescent rockfalls on the steep slope.
