Ok, so I just got the smack laid down on me. But the bottom line is this, it takes a fairly large quake to wake me up and an even bigger one to get me out of bed. So in essence, I'm creating a new scale. The Arty Scale. So the next time there's a quake, NBC should call me. If I woke up, it's worth reporting. If I ran out of bed, they should cancel all other stories and go exclusive. :D
As for the Sylmar quake, I wasn't born yet. So that doesn't make the Arty Scale. Same goes for the Seattle quake. Those coffee drinking yuppies needed a wakeup call. :D :D :D (Is there a limit on smilies?)

Geo Question
I've never gotten a good answer to this question: when is it an aftershock? When we have 6ers and then feel little 1ers and 2ers afterwards, the latter are obviously considered aftershocks (the plates settling into position again or .....). What about this rash of 4ers and 5ers following the 6.0? I didn't have access to the internet way back in the days of college (eons ago!), but it seems that these are a lot of very large aftershocks coming on the tail of a fairly robust earthquake.
I'm seeing a lot of 3-5s all along the San Andreas and a few other areas where I can't find a known fault. Baja is having some activity as well. Just wondered what anyone knows about this. It just doesn't look good to me. Did they finally get everyone to jump off a chair at noon central time? :(

got my first wake-up quake last night.

Aftershocks are a result of the fault settling in to it's new position. I could go on and on in detail about this, but I have a TPS report to produce by the end of the day. Here's how I'd put it in layman's terms:
When the main earthquake occurs (and the rocks along a fault physically shift in order to relieve built up stress or tension), it's never a perfect fit or position for the rocks. As such, they adjust (or have aftershocks) to better fit into thier new position. Sometimes these adjustments are nearly as great as the original move (or main earthquake), or they're relatively small.
In addition, there are usually aftershocks and smaller earthquakes on nearby faults, since the tension or stress has changed. In extremely rare cases, they can cause an even larger quake then the original quake (either on the same fault or on a nearby fault).

That a lot of quakes
