max-flow-depth: Raster image depicting maximum composite flow depths over dry land. For each grid point, the pixel value provides the modeled depth of water (in meters) over previously dry land, representing the maximum depth value of all calculated tsunami scenarios. max-inundation: Estimated, "maximum credible scenario" inundation line(s) that encompasses the maximum extent of flooding based on model simulation of all credible source scenarios and historical observations. The maximum credible scenario inundation lines are intended to be utilized as a basis for local tsunami hazard planning and development of evacuation maps. scenario-01: Scenario 1: Mw 9.2 earthquake; 10 km (6.2 mi) depth scenario-02-pbie1: Scenario 2: Mw 9.25 earthquake; 20 km (12.4 mi) depth; splay fault scenario using the Patton Bay fault with 60 degree dip. scenario-02: Scenario 2: Mw 9.25 earthquake; 20 km (12.4 mi) depth scenario-03: Scenario 3: Mw 9.0 earthquake; 30 km (18.6 mi) depth scenario-04-pbie1: Scenario 4: Mw 9.3 earthquake; 20-30 km (12.4-18.6 mi) depth; splay fault scenario using the Patton Bay fault with 60 degree dip. scenario-04: Scenario 4: Mw 9.3 earthquake; 20-30 km (12.4-18.6 mi) depth scenario-05: Scenario 5: Mw 9.3 earthquake; 15-20 km (9.3-12.4 mi) depth scenario-06-pbie1: Scenario 6: Mw 9.25 earthquake; 25-30 km (15.5-18.6 mi) depth; splay fault scenario using the Patton Bay fault with 60 degree dip. scenario-06: Scenario 6: Mw 9.25 earthquake; 25-30 km (15.5-18.6 mi) depth scenario-07-bs: Scenario 7: Mw 9.3 earthquake with 35 m (114.8 ft) of maximum slip in most of the rupture; splay fault back thrust scenario using a 30 degree dip at the surface. scenario-07-pbie1: Scenario 7: Mw 9.3 earthquake with 35 m (114.8 ft) of maximum slip in most of the rupture; splay fault scenario using the Patton Bay fault with 60 degree dip. scenario-07-pbie2: Scenario 7: Mw 9.3 earthquake with 35 m (114.8 ft) of maximum slip in most of the rupture; splay fault scenario using the Patton Bay fault with 45 degree dip. scenario-07: Scenario 7: Mw 9.3 earthquake with 35 m (114.8 ft) of maximum slip in most of the rupture scenario-08-pbie1: Scenario 8: Mw 9.3 earthquake with 50 m (164 ft) of maximum slip close to the trench; splay fault scenario using the Patton Bay fault with 60 degree dip. scenario-08: Scenario 8: Mw 9.3 earthquake with 50 m (164 ft) of maximum slip close to the trench scenario-09: Scenario 9: Mw 9.25 earthquake; 10 km (6.2 mi) depth, slip extending to 0 km depth scenario-10: Scenario 10: Mw 9.0 earthquake with 50 m (164 ft) of maximum slip in the shallow part of the rupture scenario-11: Scenario 11: Rupture of the Cascadia subduction zone, including the entire megathrust between British Columbia and northern California
