It hit @ 8:04pm and there were not a lot of people in the building which is why I got out so quickly (plus I used to run track and running stairs was part of the training). It was registered 5.6 and on the Calavaris Fault. Not here in the city but there have be several after shocks too.

I felt it!

I was at home and it was rather intense there so I was quite glad I wasn't at work. I heard it maybe a split second before the shaking started. The rumble of the actual house shaking and things inside moving. When the house didn't stop shaking, I bolted for a doorway (door jam) until it stopped. What gets me is the waiting for possible aftershocks. Every time I hear something that I can't right away recognize, say a large truck going by outside, my adrenalin started pumping thinking it might be an aftershock. It usually takes a while before I stop reacting to normal sounds thinking it's another quake.

I heard it a second before also. It really freaked me out because my office is on the 19th floor. My mom didnt feel it @ home because our house is on solid granite (if you know it San Bruno Mt.) I just wanted to get out of the downtown area ASAP. BART had to stop to check the tracks which is standard so I caught a cab home. Ugh...

Did anything fall in your home?

Nothing fell. Or nothing that I have noticed yet.

I saw a map a while back (I've been trying to find it on line) showing the various areas in the Bay Area and which areas were on "solid" ground (rock?) and those that were not. As I recall, my home is in an area that is on solid ground. Just not sure if it is rock or not. This is why I kind of freaked yesterday. I haven't heard/felt anything as intense since 1989 so this one really got my adrenalin going.

And I so hear you about getting out of downtown. I was at work during the '89 quake and it took me almost four hours just to get across half of San Francisco.

Wow, that's nuts. I was in school @ Grambling (Louisiana) when that one hit. I'll see if I can find that type of map cause Im interested too. I have seen maps of the original shoreline of San Fran. My building is on landfill

Earthquakes are the weirdest experiences. The big one we had here in Seattle in 2001 (I think a 7.0) was wild...the floor really felt like it was rolling.

I remember hearing about that one. I also remember when Chicago had one way back when. It's interesting to hear accounts from people who aren't used to them. What folks seem to forget is that there are fault lines all over the US but some are a lot more active than others.
