The INGV (National Institute of Geophysics and Volcanology) seismic network detected a rapid increase of continuous vibrations (so-called tremor) associated with a degassing at noon (12:10 local time) yesterday.
Volcanic tremor reached temporarily high values, indicating magma moving upwards through the volcanic conduits, and later on showed significant variations following a decrease to medium values. A sharp spike of high amplitude tremor returned back at 11:30 local time with an increasing tendency. The tremor has been located between the Bocca Nuova crater and the Southeast Crater at an altitude 2500 meters.
Moreover, a seismic crisis has continued to evolve from 14:44 local time.
A volcano-tectonic earthquake with magnitude M 1.9 was registered at 15:00 local time following a small explosive eruption at the same time.
No significant ground deformation was detected.
Local visibility was very limited due to dense clouds, which didn’t allow scientists to observe the activity via surveillance cameras.
