Abstract

Abstract

Abstract The Cascadia subduction zone (CSZ) is capable of producing large megathrust earthquakes and tsunamis, posing substantial risks to the Pacific Northwest. This article examines the seismic characteristics of the CSZ, including its offshore coupling, sparse seismicity, and a complex paleoseismic record. Recent advances in geophysical methods and data collection have improved our understanding of subduction zone processes, but important uncertainties remain regarding rupture dynamics, ground shaking, and tsunami impacts. The Cascadia Region Earthquake Science Center (CRESCENT) has been established to address these challenges through coordinated research, education, and community engagement. By integrating scientific studies, fostering collaboration, and leveraging new technologies, CRESCENT seeks to improve hazard assessment and resilience in the region. This article outlines the primary challenges and opportunities for advancing subduction-zone science and supporting societal preparedness for future CSZ events.
