Volcanic crisis management supported by near real-time lava flow hazard assessment at Piton de la Fournaise, La Réunion

A near real-time lava flow hazard assessment protocol, implemented at Piton de la Fournaise (La Réunion) since 2018, significantly enhances volcanic crisis management by providing rapid, discharge-rate-dependent hazard maps. These maps, shared with civil protection within hours of an eruption, improve mitigation strategies through iterative collaboration between scientists and authorities. The study demonstrates how this integrated satellite data-driven approach tailors hazard assessments to local needs, addressing gaps in real-time decision-making during effusive crises.
