Rock microstructural and mechanical constraints on the 2021-ongoing hydrothermal unrest at La Fossa Caldera (Vulcano Island, Italy)
Volcanic unrest associated with increased hydrothermal activity is often difficult to interpret, yet it may culminate in hazardous steam-driven explosions or slope failures without magma intrusion. At La Fossa Caldera (Vulcano Island, Italy), recently affected by the 2021–ongoing unrest episode, we identify a porous...
