Etna volcano update: Strombolian activity from SE crater calms down; lava flows into the Valle del Bove generated small pyroclastic flows.

On Saturday late in the morning the explosive activity from the SE crater stopped.

From that moment on the activity became mainly effusive, although some weak strombolian explosions and ash emissions were observed for short periods at the upper vent.
A series of small pyroclastic flows occurred along the steep western wall of the Valle del Bove caused by the unstable ground and the interaction of the lava with patches of remaining winter snow.
The most violent sequence of pyroclastic flows occurred at around half past four on Saturday afternoon when part of the western headwall collapsed, resulting in large ash and steam plume.
Currently the lava flows remain very weakly active with the most advanced front reaching about 2850m ASL toward mount Frumento Supino.
Night-time glow continue to be observed at the Voragine crater. It has become more intense yesterday night and seems to have decreased again today.
Tremor has descended back to low levels.

Towards the end of the second eruption of Etna in 2017 (15-20 March), an unusual phenomenon occurred: the lower lava flow, originating from the 2900 m fissure vent at the base of the SE crater and descending into the Valle del Bove from its western rim at 2500 m elevation, produced a series of small to moderate pyroclastic flows, associated with dense ash plumes. ...

The explosive-effusive eruption continues strongly. Several well-alimented lava flows are descending into the Valle del Bove from elevations between 2500-2700 m at the rim. ... [more]
