Renewed volcanic activity near Mammoth Lakes, California, in the form of dome-collapse pyroclastic density currents (PDCs) from either a new eruption at Mammoth Mountain or the Inyo craters would pose a significant hazard to critical infrastructure there. This paper compares the risk from PDC...

Digital elevation models (DEMs) used in geospatial analysis like the simulation of geophysical flows, such as floods, landslides, and block and ash flows, differ in resolution, acquisition time and generation methodology, which results in varied representation of topographic features. This study...
