Dr. Erin Wirth, Research Geophysicist with the U.S. Geological Survey and Affiliate Assistant Professor at the University of Washington, presents "Preparing for the Big One" at 2019's Three Days of Preparedness on Bainbridge Island.
It's good, but could've been better presented in this video format. It's frustrated they didn't show some of the animations I really wanted to see. But still cool presentation
Good presentation, but it sure would have been nice to see the slides instead of just the pointer during some of the key points. Thanks for posting this importantant talk.
This geologist found this interesting and appropriately indecisive. The truth is, there are countless variables with any big shake. I'm glad I like in the relatively benign midwest (New Madrid being the exception of course.)
Cascadia is a terror on the coast but we have active faults inside of Puget Sound that are 1/2 to 1/8 as active. They go off every few thousand years roughly. They could generate a 7.5 or so and are capable of several meters of uplift or drop. Locate it on the shore, inside of admiralty sill at the right tide and you have 10 meter sunamis bouncing around for 6 hours. South Whidbey is one we are aware of and there are many we are not aware of. We are living in an area with no history. Pre-historic in the puget sound? Anything before 1700. We don't know and we have not studied. We do know that in this region the plates are destroyed by continental drift. We are nowhere near a craton.
Whether the next earthquake is caused by the subduction or slip zone, if it is greater than 8.5 what are the chances of the shockwaves affecting Yellowstone Park and triggering Old Faithful?
What do you think happened at Fukushima? Every analysis I've seen indicates that three reactor cores at least partially melted. That aside, don't let one quibble prevent you from seeing the rest of an interesting presentation.
