A friend (non-engineer type) toled me this weekend that they heard some new information on this fault on a TV news broadcast last week.

Supposedly, some new information regarding this fault was discovered from recent activity on an adjacent fault. It's now supposedly rated somewhere between a magnitude 8.0 to 9.0 on a possible future event. This magnitude rivals the Cascadia Subduction zone effect and I find it very hard to believe, although the faults are only separated by about 300 miles as the crow flies.

Can anyone verify this? I did not see any news information.

i'm not up to speed on that area, but this article mentions M7.5...jumping from M7.5 to 9 is a huge jump and seems a little far, but again, i've not done a lot of reading on that particular fault. the latest usgs report suggests a M7.5 for that specific fault. (search "whidbey" and you'll see the references).
here's another usgs report turned up with a quick search.

Thanks. I'll take a look. Sounds like they probably misread the article, assigning 8 to 9 to a 7.5. Anything for print, right?

FYI, the last link comes up unavailable.

From reading another recent article, the UGGS is now saying that the Seattle Fault, a long recognized hazard at a 7.2 level, may be a lateral branch of this same Whidbey fault, now rated at 7.5+. It's also interesting that they now think that the longer the faultline, the greater the larger quake potential. Makes sense from an energy - spring theory - level.

And the light gets brighter... I just hope it's not magma breaking the surface... [nosmiley]
