Short summary
At Piton de la Fournaise, eruptions are typically fissure-fed and form extensive lava flow fields. Most historical events have occurred inside an uninhabited caldera, but rarely has lava flowed where population and infrastructure might be at risk. We present an up-to-date lava flow hazard map to visualize the probability of inundation by a lava flow per unit area that is an essential tool for hazard mitigation and guiding crises response management.
