Short summary

There is a need for large-scale comparable assessments of volcanic threat, but previous approaches assume circular hazard to exposed population. Our approach quantifies and ranks five exposure types to four volcanic hazards for 40 volcanoes in Southeast Asia. Java has the highest median exposure, with Merapi consistently ranking as the highest-threat volcano. This study and the tools developed provide a road map with the possibility to extend them to other regions and/or towards impact and loss.
