Lahars impose significant secondary hazards on highly populated volcanic islands by remobilizing volcanic ash deposits. Karthala, on Grande Comore Island, is a relatively young and poorly eroded basaltic shield volcano with sporadic occurrence of ash

Managing the progressive awakening of Karthala volcano (Comoros Archipelago) after 14 years of quiescence: lessons learned from a long phase (2021-2023) of unrest

Autor: Marco Liuzzo

Karthala shield volcano (Grande Comore) is the most frequently active volcano of the Comoros Archipelago. On a centennial scale, Karthala alternates phases of dominantly eccentric activity, when eruptive fissures open along the rift zones cutting the

International audience; Basaltic eruptions are commonly associated with lava emissions and relatively weak explosive activities, but they can sometimes produce strong explosive eruptive phases. In April and November 2005, two paroxysmal eruptive even
