This March 28, 2020 at 16:44 UTC, the geophysical monitoring network of the Laboratory of experimental geophysics #LGS of the Department of Earth sciences of the University of Florence recorded an increase in the seismic tremor at Stromboli, accompanied by events of roll (such as "rockfall"), the longest of which (approximately 3 minutes) took place at 16:57 UTC.

This phase of increase in tremors is associated with an overflow, that is to say an overflow of lava, from the NE crater as in the images of the Labronzo camera and caused the collapse of small portions of the edge of the crater.

 

At the moment, there is no significant change in the other parameters monitored. This activity is still ongoing.
