GSA 2021 session: T11. Recent to Long-Term Slip Histories of Active Faults and Folds in Cascadia

This is an interesting topical session at the GSA 2021 meeting:

‘T11. Recent to Long-Term Slip Histories of Active Faults and Folds in Cascadia’  

at the 2021 Annual Meeting of the Geological Society of America. We hope to attract a diverse array of talks that explore the faults and folds in the upper plate of the Cascadia subduction zone that are both active and have protracted histories of fault slip. We welcome submissions summarizing recent tectonic geomorphologic, paleoseismologic, geodetic, seismic reflection, and other data that characterize deformation of Quaternary-active structures and seek contributions from geologic, geophysical, and related research that examines the longer-term history of active faults. We particularly invite studies in the forearc, arc, and backarc of Cascadia that bridge the gap between Quaternary evidence of fault activity with longer records of fault slip that may address the consistency of slip rates over time and the timing of fault/fold initiation. 

Confirmed invited speakers

  • Ray Wells (USGS – Portland)
  • Megan Anderson (WA Dept of Natural Resources)
  • Christine Regalla (Northern Arizona Univ)

The Annual Meeting takes place Oct. 10 -13, 2021 in Portland, Oregon. GSA is planning for an in-person conference. Fall is a beautiful time in Oregon. This and other sessions provide a wonderful opportunity for scientists working on all facets of Cascadia to reconnect. We hope you come to the meeting and participate in the session. 

Submit your abstract by the July 20 deadline
