Project Highlights 2005 - Cascadia Episodic Tremor and Slip Event

Cascadia Episodic Tremor and Slip Event

  • Principal Investigator (PI): Ken Creager, Dan Johnson & Rick Bennett
  • UNAVCO Engineers: Freddy Blume & Nicole Feldl
  • Dates: July 2005
  • Location: Clallam Bay, Washington

The campaign GPS deployment to monitor the upcoming Cascadia Episodic Tremor and Slip event is underway, with the first 3 of an expected 30 stations installed on 2 August in the western Olympic Peninsula. The project, "Stalking Cascadia episodic tremor and slip with enhanced GPS and seismic arrays", is the first EarthScope funded use of the new UNAVCO supported pool of Topcon GB-1000 campaign GPS systems. Principal investigators Ken Creager and Dan Johnson of the University of Washington and Rick Bennett of the University of Arizona hope to gain a better understanding of the periodic slow earthquakes that have been recently discovered to occur in the Cascadia subduction zone using a dense array of both GPS and broadband seismic equipment. The deployment is expected to be completed by mid-August and will last up to 3 months or until the ETS event has completed.
