Etna: Ingv Catania, new topographic map published

(ANSA) – CATANIA, DECEMBER 30 – The new topography map of Etna updated to July 2021 (summit area and Valle del Bove) has just been published in the magazine ‘Remote Sensing’ (The National Institute of Geophysics and Volcanology announces it of Catania. The map was produced thanks to a new satellite data ‘fusion’ procedure elaborated by Tania Ganci. The study was supported by the Ingv ‘Dynamic Planet’ project.

The high resolution map can be downloaded as ‘Supplementary Material’ within the article, freely accessible.

198 “Very active volcanoes such as Etna – says the Ingv volcanologist of Catania Marco Neri – significantly modify their topographic surface with great frequency, especially in the summit areas, i.e. those most exposed to the covering of new lava flows, erosions and collapses Also for this reason it is very important to always produce new topographic maps of the portions of the territory that are constantly changing, also to update the three-dimensional models of the terrain on which to simulate the propagation of lava flows”. “For example, the lava flow active since the first days of December 2022 and emerging from an eruptive fissure that opened at the northern base of the Southeast Crater, albeit modestly fed – concludes Neri – is already modifying the morphology and altitude of those places”. .
