Yeah, we'd need to borrow ferries from somewhere. But if it's the big one, Puget sound is also probably a mess so there goes the obvious option.

- lotsofpulp 3y agoWhat would happen to the sound in the event of an earthquake? I figure equipment to unload boats might be damaged, but the boats themselves should be able to come and go as before, no?
- jasonwatkinspdx 3y agoThe cascadia subduction zone extends from north of Vancouver island to NorCal. The sound is expected to see 8+ on the Richter scale. So they'll probably have too many of their own problems to lend help to Portland.
- ianburrell 3y agoBTW, the quake won't be that strong at Seattle and Portland. The subduction quake could be up to magnitude 9 but that is off the coast and over the mountains. I have seen estimates of magnitude 7-7.5 shaking in Portland. However, it will be 5 minutes of shaking which will liquefy soils. The result is that most buildings in Portland will survive. Only unreinforced masonry and liquefaction areas will have serious damage. The quake is survivable, the problem is infrastructure wasn't built with quake in mind.
