|
| Regular commute and business traffic would disappear, of

|
| None of those things are true for the Columbia River
| separating Oregon and Washington. There aren't many bridges
| and they're very long. The river is non-trivial to cross.
| That would be a big mess.

|
| Living in California, we get public service announcements and
| outreach about preparedness. The FEMA guidelines of 3 days
| supplies are a fine rule of thumb for a lot of disruptive
| scenarios. I personally feel a 2 week ability to "shelter in
| place" is about the best one can hope for. But all of those
| rely on the underlying detail that should some great disaster
| hit an area like Southern California, that there is a large
| amount of infrastructure and support outside of the area that
| can be marshaled and rallied to support those impacted by the
| event.
|
| Simply put, within 2 weeks, not only has the cavalry arrived,
| you're likely already on your way out to a safe area.
|
| Mind, I live in a earthquake zone. My singular true risk is
| uncontrolled fire. Modern, wood stick frame housing is very
| resilient and resistant in collapse in case of a large quake.
| It can condemn the house, but the house will not likely crush
| the occupants.
|
| But fire, well fire is fire. We, unfortunately, know far too
| much about the disaster potential for fire. So, my hope is that
| at worse the house gets broken, doesn't catch on fire, and
| someone will show up within 2 weeks helping me get to someplace
| else. Other than that, just gotta wing it.
|
| 2 weeks of random soup and beans from a can is not a hard thing
| to stock up. Water is a trick if you're not doing it
| consciously, but it's not up to the rafters with supplies if
| you do.
|
| Oregon, however, is just not so lucky. If they get their
| planned for monster earthquake, it's very likely help will not
| be able to arrive within 2 weeks. You're likely looking at a
| much more apocalyptic scenario rated at several months. If
| anything, you should prepare to start hiking out.
|
| The infrastructure impact seems to be very high in Oregon. Even
| nearby help may not be able to get to you, with the roads being
| in utter ruin.
|
| So all I can hope is that there is effective outreach to the
| folks in Oregon and some solid advice shared on how to
| potentially cope with these events should they happen. Because
| Oregon has different issues and the generic guidelines likely
| will not be successful in this case.
