Description: DOGAMI scientists modeled tsunami scenarios for local-source (Cascadia Subduction Zone, or CSZ) and for distant-source (Gulf of Alaska subduction zone) tsunamis. CSZ scenarios can show a wide range of inundation in the same area. To make it easier to understand CSZ inundation scenarios for different earthquake sizes, the sizes are labeled like T-shirts: small (SM: magnitude ~8.7), medium (M: magnitude ~8.9), large (L: magnitude ~9.0), extra-large (XL: magnitude ~9.1), and extra extra-large (XXL: magnitude ~9.1). For distant-source earthquakes, DOGAMI scientists modeled two inundation scenarios: one simulates the 1964 Alaska magnitude 9.2 earthquake and tsunami (AK64); the other simulates a hypothetical maximum considered Alaska tsunami from a magnitude ~9.2 event with more seafloor uplift and positioned to focus tsunamis at the Oregon coast (AKMAX).
