I present material about the Cascadia subduction zone at the Sundays with wine held on 8/28/16 at Wild Wines in Little Applegate Valley in southern Oregon. This page has some supporting material from this presentation, including the digital presentation file.

Here are some sources of information about the Cascadia subduction zone

• For the 315th anniversary of the most recent full rupture CSZ earthquake I put together a summary of our state of knowledge about the CSZ and that 1700 A.D. Jan. 26 earthquake. 2015.01.26
• The USGS (and others) put together an educational video about the CSZ. I post this video and other supporting information online here: 2015.10.08

Here are some links to other online resources about the Cascadia subduction zone:
• The Redwood Coast Tsunami Work Group Living on Shaky Ground: Preparing for the next Cascadia subduction zone earthquake and tsunami
• USGS: Atwater et al. (2005): The Orphan Tsunami
• USGS: Prehistoric Earthquakes along the Cascadia subduction zone: Goldfinger et al. (2012): The Turbidite Record
• Tsunami Hazard Maps for the entire state of Oregon: Oregon Tsunami Hazard Mitigation Program
• NOAA Center for Tsunami Research: Pacific Marine Environmental Laboratory

Here is an educational video about Cascadia subduction zone earthquakes and tsunamis.

Here is a tsunami hindcast for the Jan 26, 1700 Cascadia subduction zone megathrust earthquake that may have ruptured all the way south to Humboldt Bay. This is the download link for the embedded video below (35 MB mp4).

Here is an animation showing the Holocene record of earthquakes along the Cascadia subduction zone (Goldfinger et al., 2012).

Here is an animation of a Cascadia subduction zone earthquake generated tsunami. This is the download link for the embedded video below (15 MB mp4).

Here is an animation of the numerical simulation for tsunami inundation at Cannon Beach (Ecola Creek).
This was prepared by Rob Witter (Witter, 2008 ).
