Toward an Integrative Geological and Geophysical View of Cascadia Subduction Zone Earthquakes

The Cascadia subduction zone (CSZ) is an exceptional geologic environment for recording evidence of land-level changes, tsunamis, and ground motion that reveals at least 19 great megathrust earthquakes over the past 10 kyr. Such are among most impactful natural hazards on Earth, transcend national boundaries, can have global impact.Reducing societal impacts future events in US Pacific Northwest coastal British Columbia, Canada, requires improved scientific understanding earthquake rupture, recurrence, corresponding hazards. Despite substantial knowledge gained from decades research, large uncertainties remain about characteristics frequencies CSZ earthquakes. In this review, we summarize geological, geophysical, instrumental relevant to along associated uncertainties. We discuss how constrains various models recurrence identify potential paths forward science community. ? outstanding records events, uncertainty magnitude frequency remains. This review outlines current promising directions address questions rupture recurrence. Integration diverse data sets with attention processes create different has lead major progress.
