I presented a talk to a senior seminar for the Defense Support of Civil Authorities (DSCA) in regards to their efforts to prepare for the disaster following a Cascadia subduction zone (CSZ) earthquake and tsunami. The Department of Defense provides support to local, regional, and federal organizations following disasters, natural or otherwise.
I post some supprting material below, as long as some of the references that I use in this presentation.

Here is the digital presentation that I prepared for their seminar in Portland, Oregon
- 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 sources of information about the Cascadia subduction zone
- 2014.03.09 M 6.8 Gorda plate p-1
- 2014.03.23 M 6.8 Gorda plate p-2
- 2014.03.13 M 5.2 Gorda Rise
- 2015.11.18 M 3.2 Gorda plate
- 2015.06.01 M 5.8 Blanco fracture zone p-1
- 2015.06.01 M 5.8 Blanco fracture zone p-2 (animations)
- 2015.01.28 M 5.7 Mendocino fault
- 2015.11.01 M 4.3 Mendocino fault
Elsewhere on my website, I summarize these reports by region here. I also post some of the earthquake reports associated with different regions of Cascadia here:

Here is an animation of the numerical simulation for tsunami inundation at Cannon Beach (Ecola Creek).
