1. A Database and Working Group for Cascadia Earthquake Research:Synthesizing Existing Knowledge to Answer Outstanding QuestionsMaureen Walton, Research Geologist, USGS (Santa Cruz, CA)Lydia Staisch, USGS (Mountain View, CA)Jon Perkins (Mountain View, CA)Janet Watt, USGS (Santa Cruz, CA)Rob Witter, USGS (Anchorage, AK)Joan Gomberg, USGS (Seattle, WA)
2. Modern instrumental recordsSynthesize modern evidence for deformation, plate motion, and seismicityLeft: GPS, seismic stations, multibeam bathymetry coverageLegend
3. Structural controls on earthquake rupturesLook at onshore-offshore structures that might control earthquake rupturesLeft: multi-channel seismic reflection (MCS) lines, LiDAR, mapped faults, seismicity45o N50o N40o NLegend
4. Geologic evidence for earthquakesRevisit geologic and paleoseismic data that can help us address megathrust earthquake recurrenceLeft: lake cores, coastal tsunami deposits, marine coresLegend
5. Geophysical dataGather all existing data into a publicly accessible database with attributes, download links, and interactive mapLeft: potential field data (gravity), offshore geophysical tracklines45o N50o N40o NLegend
