View of the Valle del Bove
The videos show the view from Schiena dell’Asino locality on the southern wall of the Valle del Bove. In the background, the New South East Crater and the Serra Giannicola Ridge surrounded by the well-recognizable, 24 December 2018 lava flow. The Valle del Bove is a “horseshoe” shaped depression, 7 km wide and more than 1000 m deep, showing the inner portion of the older, Mt Etna volcanic edifices. In present times, during effusive eruptive episodes, lava flows are often channelized along this depression.
Recent tectonic activity
The video shows a segment of the active Pernicana fault system, crossing, cutting and offsetting a road (S.P. Mereneve) along the eastern flank of Mt Etna volcano.

Example of historical volcanic eruptions
Mts. Silvestri are a row of pyroclastic cones aligned along a N-S trend, on the S flank of Mt. Etna, and are related to the lateral 1892 fissure eruption.

Mts. Sartorius are a row of pyroclastic cones aligned along a ENE-WSW trend, on the NE flank of Mt. Etna, and are related to the lateral 1865 fissure eruption, which occurred at an altitude of about 1800-1750 m a.s.l., and lasted about 6 months.
