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!

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 !!

I guess this is 4 yrs old. I find it amazing and wish my dumbass son had found a beauty with brains like you so I could withdraw support.

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

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.

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

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

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.

stupid camera work

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.)

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

So the powers that be are clearly going to hit these areas with their HAARP weapons………how do people not see this??!! 🙄 WAKE UP!

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

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?

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

You people can't even deal with the anarchy right under your noses. How can you even suggest that you have the ability to prepare for an onslaught of this magnitude from Mother Nature? (Other than pack your bags and leave NOW)

Our latest extra training was from local electric utility telling about how electricity works, why littke birds don't get electrocuted, and why you need to learn to bunny hop if the ground is hit by lightning or there is a downed power line.

Do you actually have the flip book?? We thought they were no longer available.

Too much sample spray thrown in.. something is off here.

Please add the video graphics of the earthquake simulation to Dr. Wirth's Cascadia earthquake lecture. The comments are turned off on that video so I am leaving one here. And because those videos are not on her lecture it is missing a huge piece of her lecture. You guys added the screenshots, why not also add the videos she used? Please let the content creator know. Thank you! I am glad I found this channel! I am appreciating all of your videos and I believe more Northwest folks need to see them! I am sharing your videos with my friends and family.

Where did you get your vest My vest is the standard issue one and I want to get one that has a couple of pockets

I'm glad I watched this, I volunteered to become a cert. I start the 31st

I had 2 runs on this, the first one I could smell the solution rather than taste it. 2nd test went better, with me getting the cup - shaped 1860. I escort ppl to appointments (no direct patient contact) but thought I'd get tested, just in case.

Great video. Very informative.

Lost me when they had the lady put a plastic bag over her head.

So the whole idea of the test is the find the mask that fit your face and can prevent substance trough the mask. Is that correct? How do you provide the masks to the customer because there are so many brands and sizes out there.

why did you put a plastic bag over her head? you should put the hood on during the sensitivity test.

I have a few questions and thoughts if you have time... What do you think of masks with exhalation valves? I'm not sure I care for them since a valve cannot magically close, instantaneously. One would have to believe a few particles could slip through each time you inhale(?). Also what are your thoughts on wearing eye-protection with this new super-strain entering the battlefield? Do you think air-tight anti-fog goggles will be essential? I have a health condition so I'm concerned, but luckily I only have to go out occasionally for food or pharmacy. For short durations, such as shopping, the safest looking solutions I've found so far are; rubber gasket respirators, Redimask, and modified full-faced snorkel masks. Recommendations? Questions for me? I appreciate you guys! Take care. -Mark
