Strombolian activity at Mount Etna, Italy
Strombolian activity with sporadic ash emissions continues intermittently at Mount Etna's 'saddle crater' since around July 10, 2020.
The image below shows strombolian activity at the newest crater, referred to as the 'cono della sella' (saddle cone). The crater emerged during early 2017 in the area between Southeast Crater (SEC) and New Southeast Crater (NSEC).

At the same time, there is also a strombolian activity within the Northeast Crater, and there are sporadic ash emissions from the Voragine Crater.
Finally managed to get to 3300m altitude – the top of #Etna yesterday.
Amazing to gaze into the Central Crater before traversing round the west ridge to look at the new SE crater and saddle vents.

A quick look through the eyes of ESA's Sentinel-2 satellite reveals a prominent thermal anomaly over the volcano today:
