Tim Walsh: Landslides, Earthquakes, Tsunamis, Volcanic Eruptions: They all happen in Washington. Why? What does it cost? What can we do?

Preventing the impacts of liquefaction, for example, can be minimized by using pilings in places where you know liquefaction might occur.

Also, not building in places where bad things, like landslides, might happen. Geologically hazardous areas.

Building codes.

Average annual loss from landslides is more than $20 million.

(To be honest, I’m doing a bad job summarizing this talk, please feel free to add a comment if you have a question, I’ll try to track Tim down to answer anything I’m missing)

They’re working with FEMA to create structures that would protect people during a tsunami even if they couldn’t get out of the way. For example, the new Ocasta High School.


Climate induced change and our vulnerabilities?

More storminess and more rainfall, you’d expect there would be more landslides. Or, the opposite. More wildlifes in the cascades, so burned slopes would be more likely to slide.

Are our building codes up to a 9 earthquake?

The current map takes into consideration all the possibile earthquakes, so it takes into consideration a Cascadia event.
