Dr. Erin Wirth - "Understanding Cascadia's next Great Earthquake" at 2019 Three Days of Preparedness

[@donrose787]

Please, always repeat audience questions. Excellent presentation.

[@maskedman1337]

This is a wonderful presentation and Dr. Wirth's tone and confidence is perfect. Thanks for posting!

[@jasonpeisley6031]

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

[@freden9234]

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.

[@leeice5347]

Exactly, I stopped watching because of that. I feel that some of the most important information was not communicated as a result. Very frustrating.

[@vlahks86]

@@leeice5347 Yes too bad a great presentation drops to a "pretty good" presentation !!

[@pat8988]

Boo to the producer who shows the speaker while there’s supposed to be a video running! ☹️ (15:50) for example.

[@vlahks86]

Yes I agree.... great presentation except for the person videoing it..... He/she should take a class in video presentations !!

I live in Santa Monica California (Los Angeles County) used to live in San Francisco. We felt it as it knocked down Santa Monica Blvd awful traffic for months. My house is new and built to current earthquake codes for California and the office I work in has been retrofitted to current California earthquake codes. I have a storm shelter with a month’s worth of food and supplies in the case of an actual earthquake emergency. I forgot to add the biggest earthquake I was in: Loma Prieta in San Francisco October 17th 1989. I was at the A’s-Giants World Series game! 15 seconds of pure adrenaline and fear! I’m glad I wasn’t on the Bay Bridge and especially not on the Cypress Expressway! P-WAVE-Primary wave S-WAVE-Secondary wave P-equals first JOLT S-equals Major Shaking!

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.)

[@AH-gk9we]

Very frustrating to not see the slides or animations at all times.

[@dancooper8551]

Excellent information. Never encourage your audience to ask questions prior to the end of your talk.

[@TheEarthMaster]

Good lecture, although in my reviews I see a high percentage of a mega quake along the Cascadia, likely 60-70 percent in the next 50 years.

[@garyjene9146]

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?

[@sherimatukonis6016]

No geographic evidence of that ever happening.

[@patb5266]

The magna chamber under Yellowstone has moved so chance of a super volcano eruption is low now.

[@vlahks86]

​@@sherimatukonis6016The Cascadia Subduction Zone and northern San Andreas Fault meet at a place called the Mendocino Triple Junction. The two faults touch at a place called the Mendocino Triple Junction, which is offshore of Mendocino County, California !! Oh boy maybe Lex Luther was right >>>> buy beach front property in Nevada !! 😂😂😂😂

[@vlahks86]

Great presentation.... >>>> TOO BAD A LOT THE VIDEO AND GRAPHICS PRESENTATION WAS NOT COVERED IN THE VIDEO !! I WOULD RATHER SEE THE VIDEO OF YOUR TALK RATHER THAN SEEING YOU TALK .... BUT EXCELLENT ..,.... MAYBE YOU CAN DO ANOTHER PRESENTATIION WITH ALL OF THE VIDEOS AND GRAPHS !! MAYBE THE PERSON VIDEOING YOUR PRESENTATION WILL LEARN FROM THIS IMPORTANT PRESENTATION AND TAKE A CRASH COURSE IN PROPERLY VIDEOING A VERY IMPORTANT PRESENTATION !!

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.

[@sherimatukonis6016]

And still, 4 years later, very little has been done to improve public structures, bridges, etc.

[@maryshank7825]

Based on what?

[@patb5266]

There were no "meltdowns" of any of the Fukushima reactors let alone 3. I stopped watching after I saw that .

[@EnerJi001]

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.
