For those not aware of the site PNSN.org they published a bulliten on the quake and will be studying it closer in the weeks to come. The forecast is for more aftershocks to follow.

Just finished reading the thread, so tell me are all of the little ones along the San Andreas faultline caused from the 7.7? Are these before shocks or are they pressure releases? WHERE are our resident experts? I am going to go find the Quakewatch thread! I did see westcoast, hopefully people are posting in the 2012 EQ thread!
I wouldn't get too worked up over what we are seeing...not just yet. It is always best to error on the side of caution and caution would dictate having an emergency stash of supplies ready just in case.
Yes, this was a very large event but with large events also come a number of aftershocks. We are seeing a normal outcome so far. These aftershocks may last for days or even weeks and may number up into the hundred range or so.
The activity that is being talked about along the San Andreas fault is normal activity for that region. While the Cascadia Subduction Zone is an extension of the San Andreas fault, there is and will be constant movement through out the entire length. This is normal. The activity reported in Idaho, Nevada, and back East is unrelated.
During events like this there are those who wish to sound the alarm and panic ensues. Panic is just what not to do. If you live in a possibly affected area the best thing to do is prepare in the event something does happen.
There is no solid science or ability to predict these sorts of events..... preparation aleves a great deal of anxiety and fear.

You do realize that the Cascadia Subduction Zone is is NOT an "extension" of the slip fault San Andreas... Right? Completely different geologic interactions... with the CSZ having the highest destruction potential... danm
Hundreds of aftershocks hit British Columbia including a 6.4-magnitude tremor Sunday afternoon,following one of the strongest earthquakes to the area in decades.

If you had read my other posts you would understand that I do realize the destructive potential and nature of the CSZ.
The CSZ is an extension of the San Andreas fault. The San Andreas is a strike-slip fault to the point of of extreme most Northern California where it dives off into the ocean. From there it becomes a Subduction Zone and continues on Northward until it reaches the area where this current event has happened. It is at this point it returns to being a strike-slip fault. Yesterdays 7.7 was a strike-slip event... thus as is common with most strike-slip faults no tsunami generated.
As previously mentioned,... go back and read my other posts on this issue before you begin to flame my post.
- Your apology is accepted in advance, have a nice day.

Not true, the most recent research has concluded the Cascadia and San Adreas are connected and are part of the same fault. Just google "Monster Quake, Are We There Yet" watch the program and see. They found where the faults connect.
en.wikipedia.org... San andreas fault is not the cascadia. They are two different fault zones, as well as two different kinds. . CSZ is above the northern part of the sandreas fault. How ever these quakes are taking place outside of this zone all together, on the queen charolette fault. so I don't even see why it's being argued about.
