During the first days of the month (Aug 2019), the explosive activity of the volcano has increased further, LGS reported in its latest update on 4 Aug evening:

The activity level remains very high, both from the vent in the Central-SW crater area and the 3 active cones in the NE crater area. The eruptions have been producing eruptions rich in ash and scoria to heights of typically 200 m, often accompanied by shock waves.
Abundant lava material has been falling onto the crater terrace as well as the upper parts of the Sciara del Fuoco, generating incandescent rockfalls. Small lava flows also continue to overflow onto the upper southern section of the Sciara, originating from the collapsed SW crater area.
Emissions of volcanic SO2 have also shown a significant increase to currently 200-300 tons per day.
All monitoring data suggest an increase of the average magma alimentation rate to values of approx. 1.2 cubic meters per second, due to the recent arrival of a batch of fresh, gas-rich new magma from greater depths.

Stromboli volcano (Aeolian Islands, Italy) - Smithsonian / USGS Weekly Volcanic Activity Report for 7 August-13 August 2019 (Continuing Activity)
INGV reported that Stromboli's crater terrace activity was analyzed during 5-11 August through webcam views, and field inspections during 7-8 August. At least nine vents in Area N (north crater area, NCA) were active on 7 August, three of which had well-formed spatter cones, with Strombolian activity ejecting material 150 m high. A large scoria cone in Area C-S (South Central crater area) jetted material 200 m high. ... Read all

The level of activity remains very high at the volcano. Strong and frequent strombolian-type eruptions occur from several vents, most notably from the northeastern and south-central vents. Read all
