How tiny fossils may help us prepare for big earthquakes | All Science. No Fiction.

When the Cascadia earthquake hits, it’s going to be bad for pretty much everyone in the Pacific Northwest. One of the more frightening impacts of the “Big One” is that the Oregon coast will literally sink, heightening the effects of the predicted tsunami and permanently altering the coastline. But scientists are now using tiny fossils, called diatoms, to better understand the risks.
Working on the Oregon coast, researchers have found that these diatoms offer clues to how much land will subside and how far a tsunami could wash inland after the next big Cascadia quake.

Thank you for that fascinating little "diatomatic" geologic/tsunami investigation!! Hope you will keep us updated. You guys are great!

[@GeologyNick]

Excellent video! Former CWU grad students Tina and David doing great things. Brandon on the camera. Nice!

[@AARONMINOO]

Awesome video thanks

[@SumNumber]

The geometry of these little creatures has always amazed me but more so the intelligence involved in completing each structure in such fine detail. Cool stuff ! :O)

[@jackmcmichael3560]

This video is incredible

[@Reichukey]

I love science! Thank you for making this!

[@rexsebastian9563]

Great video very informative

[@llamalover02]

Pretty please do one of these for Mt. St. Helens modern monitoring efforts! That would be amazing!

[@ocskywatch1]

On the Coast here, Thanks

[@jasongarcia2140]

I just moved back to Oregon and I'm scared about the quake potential now I hope you stay safe

Well, Fukushima was the same type of land movement wasnt it. GPS says...

Please tell me that california will fall into the ocean.
