Long Valley volcanic region long-term vent opening maps

Abstract

The high potential of probabilistic approaches for hazard assessment was identified by the VIMESEA group during the first meeting. In this context the INGV group has developed a novel approach that was first applied to the Phlegrean fields in Italy. This presentation was aimed to present further application to other volcanic areas in the world to address probabilities of volcanic vent reactivation. Though the message delivered by such simulations to civil authorities in charge of volcanic crisis management may not be straightforward, the VIMESEA participants concluded that the probabilistic approaches are essential for hazard assessment.
