Summary

The USGS Powell Center Cascadia earthquake hazards working group compiled published onshore and offshore paleoseismic data along the Cascadia subduction zone, spanning sites from Vancouver Island to the Mendocino triple junction. Evidence for megathrust rupture includes coastal land-level change, tsunami inundation, onshore shaking proxies such as landslides or liquefaction, and offshore shaking proxies such as marine turbidites. The quality of paleoseismic data for megathrust rupture along the Cascadia subduction zone collected over the past three decades varies because analytical capabilities and data collection methodologies have evolved. Thus, as part of the compilation, we also present a ranking scheme to assess the quality of [...]

Purpose

Compiled paleoseismic data in Cascadia supports future research both within and outside of the paleoseismic scientific community. This compilation was constructed and evaluated to include sufficient detail to be useful for a wide audience. For example, explicit values of coastal deformation with uncertainty, tsunami inundation, and ground motion constraints may be used by modeling colleagues to assess variability in past rupture characteristics. The compilation is also useful to identify spatial and temporal data gaps and future research opportunities.
