Last night (3 March 09) about 9:30 pm I felt, along with thousands of other locals in Southern California, a very strange house-rattling that set us all on edge.
As a Physical Geog professor and long-time California resident I've experienced hundreds of earthquakes - and this was definitely not one at all. None of the earthquake monitoring sites show anything of note, the local airports and regional military bases all say no operations, and nobody seems to know what caused it.
It was a quick rattling of a few seconds, rather noisy, causing the windows to rattle, doors to shake in their frames, and setting the dogs in the neighborhood off on a barking frenzy. There was no ground movement felt and the typical 'signs' we come to expect following an earthquake were altogether absent: chandeliers swinging, swimming pool water rocking back-and-forth, etc.

The santa cruz event was 12 hours later
I remember when the space shuttle used to land at edwards, it would pass over where i live at about 100k'-80k'.
There was no boom per se, but just a passing rummble

Your description of the event is quite spooky. If you live in an active EQ zone along with regular sonic booms, you most likely know when it doesn't feel "usual". If someone was rattling my windows and doorknobs at night, I'd be scared.
I posted in the other thread a theory on the footsteps sound. Is it possible other animals (squirrels, raccoons, bats, other people's cats etc) that may usually nest above your home, roof, attic etc may have reacted as pets did, and made those sounds as they scrambled away? Or did it really sound like something heavier walking around? Just curious, since you're one that heard these sounds.

I'm still surprised that there is talk of any type of sonic wave here.
Say it was a secret hypersonic aircraft flying through the valley in Riverside. The sonic wave still has to travel and spread at 750 mph,
How could someone in San Franscico and Orange County 400 miles away, feel the wave at the same time? Or even Tenessee and Portugal?
The notion of a sonic boom is impossible due to the wide area that felt it at the same time.
Even assuming a sonic wave could travel 400 miles from origin, it would still tae quite a few minutes to reach it.
I witnessed this event in my house in SoCal, I can tell you right now, it was not a "shaking" or "vibration" it was a deliberate MOVING. Unlike a sonic boom which occasionally shakes my windows and doors and plates , this night, it seemed like someone was prying up the window pane, and leaning against it for 10 seconds or so. Then it sounded like someone broke through my window upstairs and was walking and shuffling their feet. It was VERY unsettling.
THere are reports of interior doorknobs moving and INTERIOR doors being pressed against the door jam.
Sorry fellas, but the ol' sonic boom secret aircraft explaination doesn't apply in this incident.
