[TheForge] Earthquake NNW of Anchorage...

[Jerry Frost]

We're all just fine thank you Wes. NOT being a professional builder I 
overbuilt the house a bit, not only is it 2x6 framed with seismic ties to a 
faretheewell and hurricane clips on every single joist, rafter and truss, it 
isn't too uncommon for us to get winds well over 100mph right here on the 
farmstead, but all the walls have 5" of Urethane foam insulation and the 
trusses 7" of same. The last major quake, a 7pointer about 120 miles north a 
few years ago barely made the house go bang, no rattles or shaking, nothing 
fell, nothing. Zero damage at all. A mere 5 pointer, even if it was centered 
about 40 miles from here isn't likely to do much to our place.

Darned if I know what magnitude scale the USGS is using now. I have an 
experienced handle on the Richter scale but all the info on the site is now 
in ML and I have zero idea how that feels.

On the other hand, looking over the site it seems we've had a few dozen 
quakes in the last few days a number hypocentered (?) near Hayes volcano, 
that could be interesting, we haven't been ashed for a couple years. Another 
centered within 40-70 miles of Talkeetna and a bunch in Prince William 
sound. The 1964 (Good Friday) great quake, a 9+ on the Richter scale, was 
centered in Prince William sound somewhere. It raised most of the islands 
and mainland an average of 35' while leveling most communities and clearing 
debris with tsunamis from PW sound to Hawaii.

That's the kind of action that led me to build the way I did.
