PDC inundation probability distributions and related uncertainty index for the Long Valley volcanic region, according to the physical and statistical model in: Regis Rutarindwa, Elaine T. Spiller, Andrea Bevilacqua, Marcus I. Bursik, and Abani K. Patra (2019) Dynamic probabilistic hazard mapping in the Long Valley Volcanic Region CA: integrating vent opening maps and statistical surrogates of physical models of pyroclastic density currents, submitted to the Journal of Geophysical research, Solid earth.

All the maps are available in ASCII text-file format, UTM coordinates (Northing, Easting), zone 11 North, WGS84 horizontal datum.  They are included in a zip archive. Each ASCII file is identified with a figure in the paper.

In detail:
Figure 4a: dynamic probabilistic hazard maps conditioned on a PDC event of volume of 1 km3, and based on a uniform vent opening probability distribution.

Figure 4b: dynamic probabilistic hazard maps conditioned on a PDC event of volume of 1 km3, and based on a Gaussian mixture model based on known past vent locations.

Figure 4c: dynamic probabilistic hazard maps conditioned on a PDC event of volume of 1 km3, and based on the mean values of the doubly stochastic model in Bevilacqua, Bursik, et al. (2017).

Figure 5c: uncertainty index of the PHM related to the values of the doubly stochastic model in Bevilacqua, Bursik, et al. (2017).

Figure 8ab: mean probabilistic hazard based on the model of Bevilacqua, Bursik, et al. (2017) and conditioned on a PDC event of volume of 0.01 km3.

Figure 8c: uncertainty index of the probabilistic hazard based on the model of Bevilacqua, Bursik, et al. (2017), conditioned on a PDC event of volume of 0.01 km3.
