From: Following the tug of the audience from complex to simplified hazards maps at Cascade Range volcanoes
Examples of simplified maps for four Cascade Range volcanoes show the variability that results after derivations from dissimilar parent maps. High-resolution versions are available at the website (U.S. Geological Survey 2022). Mount Rainier (a) shows color gradation of the lahar hazard zones based on detailed studies of lahar deposits. Three Sisters (b) displays color gradation of the lahar hazard zones based on LAHARZ-guided inundation modeling (Schilling 1998) and features an extensive regional lava flow hazard zone. Crater Lake hazards (c) exist well beyond the borders of both the parent and simplified maps. Reasons for limited areal extent are undocumented. Lassen Volcanic Center's simplified map (d) shows slightly modified hazard zonation style as compared to other simplified volcano hazard maps of Cascade Range volcanoes. This is due to greater complexities in this volcanic area that require more complicated representations on the parent map
