Integrating geophysical and geologic datasets along the Cascadia margin for a better understanding of earthquake recurrence and hazards - Lydia Staisch, USGS
The abundant onshore and offshore paleoseismic records along Cascadia Subduction Zone (CSZ) make one thing clear: megathrust earthquakes (M>8.0) have occurred in the geologic past, a future earthquake is imminent, and the potential impacts could cripple the region. Despite substantial knowledge gained from decades of geoscience research, the size and frequency of CSZ earthquakes remains controversial and the details are important for characterizing the variability in hazard. Megathrust earthquakes set in motion a cascade of additional geologic phenomena, such as landslides and tsunamis, that provide evidence of past events in the geologic record. Each geologic dataset provides essential and unique information on the conditions of earthquake rupture and subduction zone dynamics. Geophysical data provide a complimentary lens, with insight for possible structural or geophysical features that modulate earthquake rupture dynamics. When viewed together, these records can help answer questions about megathrust rupture frequency, the earthquake cycle along the CSZ, seismic wave propagation, and more. Since 2019, the USGS Powell Center Cascadia earthquake hazards working group has focused on reviewing, compiling, and analyzing diverse datasets along the 1100-km long CSZ. Here we present our visions, goals, and progress to date.
