The level of activity at the volcano remains very high, with little significant changes during the past days:

Strong degassing and strombolian explosions occur from several vents at average intervals of approx. 2 minutes (yesterday, the average was 28 events per hour).
The strongest originate from the Central / SW cluster of vents, which eject glowing lava scoria to up to 300 m high. Spattering (near-constant, pulsating degassing with mild lava ejections) mostly from the NE vents reached 150 m ejection height.
The lava flows in the SW area of the Sciara del Fuoco continue to be active, but confined to the upper slopes, but with frequent rockfalls tumbling down to the shore.
Tremor has been fluctuating between high and very high levels.
Staff of the INGV Catania documented the crater morphology during an overflight on 23 Aug (s. picture attached). For those familiar with the volcano before the paroxysm on 3 July, it is impressive to see how much the vents (including new ones) have changed their surface appearance. Due to the ongoing intense strombolian activity, several cinder cones have now been growing rapidly inside the crater terrace.

Stromboli volcano (Aeolian Islands, Italy) - Smithsonian / USGS Weekly Volcanic Activity Report for 21 August-27 August 2019 (New Activity / Unrest)
INGV reported that a paroxysmal explosive event at Stromboli began at 1216 on 28 August with a series of explosions likely from the Area C-S (South Central crater area). The event of strongest intensity occurred at 1217, generating an ash plume that rose more than 2 km above the crater area and a pyroclastic flow that traveled down the Sciara del Fuoco and several hundred meters out to sea. The report noted a similarity in intensity of the eruption to the 3 July paroxysmal event based on the seismic data. ... Read all
