INGV ———- RELEASE OF VOLCANIC ACTIVITY of 7 June 2022 — ETNA

The National Institute of Geophysics and Volcanology, Etneo Observatory, reports that new fractures have been observed at the base of the northern wall of the Valle del Bove, in the Serracozzo area. From the further downstream part of this fracture system, lava is being released. The emission point is located at an altitude of about 1800 m.

An inspection by INGV personnel is underway. As regards the average amplitude of the volcanic tremor, from late yesterday evening, a phase of gradual decrease is observed which has brought this parameter from high to medium-high values. The sources of the tremor are located in the SE crater area at an altitude of about 2900 meters above sea level.

The infrasonic activity is low, however the strong wind this morning may have affected the detection of infrasonic events. From an analysis of the ground deformation signals, no variations outside the noise in the last hours at the clinometric and GNSS network stations are deduced. (photo by Grazia Musumeci)
