Message 980407 - Posted: 18 Mar 2010, 6:27:31 UTC - in response to Message 980394.  

there has been some concern that a similar "megathrust" earthquake is overdue for the pacific northwest of the USA.

Southern California had a 4.4 a few days back and a funny thing happened, No aftershocks the News said, nothing, zip, zero, nada, snake-eyes, 0.

' Had some geology courses in college. No aftershocks is not always a good sign.
Sometimes the quakes are called foreshocks.
They are initially called earthquakes, then when the larger quake follows, it is redesignated as a foreshock.
I don't mean to be a harbinger of doom, just stating a fact.

Understood, Hopefully nothing will come of It, But just the same It makes for a puzzled bunch of scientists with this one.

Yea they keep telling us it could be upwards of 9.0 and that we are overdue...us and the New Madrid area.

That 4.4 earthquake has been identified now, It's the Puente Hills Fault which CBS2 News said in a Special Report was capable of a 7.5 earthquake, Still no aftershocks.

As to the New Madrid area a 9.0 would affect a lot(Rivers last time changed courses for a bit, land rose and sank, etc), Sounds like Haiti, but on a larger scale, Some would poo poo It and say It's scare mongering of course(doubting Thomases/Thomasina's), The Best advice I have is have a few big and strong Steel desks to hide under, Just in case the building Yer in collapses out there. :D

A 4.4 earth quake hardly seems news worth (unless it IS the harbinger of bigger things to come) as an 8.4 quake is something like 10,000 times as strong.

It is since the fault I mentioned runs under downtown Los Angeles, a 7.5 Magnitude quake there would be devastating, As Proximity is a factor in Earthquakes and LA has a very big Fuse beneath Its feet. :D

well if you look at the position of the series of mag 4's in that region...
and consider that it could be the southern end of the thrust plate aimed at
the PNW...i'd be concerned.
also...being 400+ miles out if it went large like the Chilean quake...
400 miles makes a taller tsunami.

A Tsunami needs a strong enough quake to either make a landslide or to raise the bottom some, Otherwise either not much will happen or Ya get all of nothing. And to a building that isn't built right, a 4.x quake would do damage, How much I don't know. Besides I didn't say anything about Chile, As quakes can happen almost anywhere, Kinda like the phone company, It reaches out and touches You, zap.

my point is that the PNW is much more densely populated than the Chilean
coast that had a large tsunami(by most standards).
it the thrust plate off of the PNW coast hit 8.8mag, we would be talking
massive devastation from flooding...probably worse than Katrina.
because of the massive amount of coastal area involved.

Then imagine if the worst happened, A Tsunami and then one of the Cascade Volcanoes being set off by said quake, Talk about first being flooded and maybe being washed out to sea and then being charred and parboiled by a Pyroclastic flow from said Volcano after the smoke column collapses, It would be Pompeii or Herculaneum all over again as the Cascades are the same type of Fire Mountain as Vesuvius is, Violent and then quiet for a good long time and then when Ya least expect It, Wham, It erupts, Hard and Angry. :(
