The activity of the volcano continues at very high levels, perhaps even increasing somewhat compared to the previous week.
Strombolian explosions, of often large size, from various vents have been occurring at rates of almost one every 2 minutes average (or 28 events per hour). Ash-rich explosions occur mainly from the Central/SW crater, while the vents in the NE crater cluster have been showing high degassing rates, accompanied by near-continuous lava spattering and medium to strong explosive activity with lava bombs reaching 150-200 m above the crater.
The new lava flow which had started at 02:35 local time on 18 Aug is still active. It originates probably from an ephemeral vent at about 550-600 m a.s.l in the Central sector and has descended to probably about 3-400 m, while glowing blocks from its front roll down and tumble into the sea. The lava flow in the SW sector, which had been active last week, in turn has ended.
The volcanic tremor is stable over very high values. Heat emission is very high, compatible with the occurrence of both effusive and intense explosive activity. The SO2 flux was measured with a slightly decreasing trend from very high to high values (yesterday: 202 tons per day).
