Our work in Cascadia has focused on reconstructing earthquake and tsunami histories in northern Oregon, and testing the use of microfossils in such studies in a tidal-flooding experiment in southern Oregon. We have also explored the role of Holocene relative sea-level change in preserving records of subduction zone earthquakes, and highlighted the Cascadia subduction zone as the type section for coastal geologic earthquake and tsunami studies. Finally, we have contributed to reviews synthesizing geological and geophysical datasets at the Cascadia subduction zone, and reviewed the drivers and projections of subsidence around the world, including the Cascadia subduction zone.
Our work in Cascadia continues, with ongoing projects testing the efficacy and precision of different microfossil groups in reconstructing coseismic subsidence, and extending quantitative reconstructions of coseismic subsidence back in time at legacy sites.
Collaborators on Cascadia projects include Eileen Hemphill-Haley, Andrea Hawkes, Benjamin Horton, Rob Witter, Alan Nelson, Yvonne Milker, Nicole Khan, Maureen Walton, Lydia Staisch
