(ANSA) – CATANIA, MAY 19 – A new lava flow has been generated from the effusive vent of Etna present at an altitude of 3,250 meters and flanks the main flow which since yesterday has been gradually cooling, like its most advanced front, located at about 2,300 meters above sea level, near Mount Rittmann. The most advanced front of the new lava flow is located at about 2,700 meters in the desert Valle del Leone.
The Strombolian explosive activity in the South-East crater continues in a discontinuous manner and with varying intensity. This is what emerges from the observations of the experts of the Catania and Palermo sections of the National Institute of Geophysics and Volcanology.
The eruptive activity of Etna was followed by the researchers of the Ingv with the Clhotsat system, through the processing of the infrared satellite images of the Seviri sensor from 12 to 18 May. Experts noted that the average eruption rate (Tadr) showed an increasing trend, peaking at 5.7 cubic meters per second at 12.30pm on May 17.
By integrating the values of the effusive rate during the entire eruptive period, the cumulative volume curve was also calculated, which is equal to 750,000 cubic meters. (HANDLE).
