yep missed it in napa too. 4.2 is kind a good size too.

 

The aftershocks are increasing in magnitude. Last one was a 2.3, before that a 2.2

 

4.2 was a pretty good one. Personally I prefer a whole bunch of little stress relief quakes opposed to; well ya know...

 

Here it comes!!! How many of you guys have disaster kits?

 

I was sleeping in a bed in South San Jose! The house shook up pretty damn good! It was definitely one that everyone felt in the house. My bed actually shook.

 

felt a little wibble wobble up here in Napa

 

I felt it ~10:10am Right near San Jose Airport.

It wasn't a violent motion, but seemed to last for a really long time - ~30 sec

 

In milipitas, really felt it. The building shook pretty well.

 

multiple small earthquakes are actually a sign of the opposite

The built up pressure is getting relieved small amounts at a time rather than in one big earthquake. They are not a "warning sign" for the big one.

 

My old geology professor said the opposite....
Think of the contenental plate as a picture hanging on a wall, and nails keep on breaking.

Of couse I also took that couse 10 years ago and memory could be hazy

 

I remember it as smaller quakes are the relief of pressure. The lack of any activity (such as the reservoir above San Mateo area) is a bigger threat because the pressure is building up on the fault. Kind of like breaking free a bolt, once you snap it free, all your force flies forward. But then again, my teacher was kind of retarded.

Unfortunately I sold my geology book a while ago.

EDIT: Seems like there are theories in both directions.

 

Either way, I've got a SHTF kit and I'm putting gas in the car tonight

 

Yup It totally woke me up this morning. I still had 30 mins on the clock before i had to get up for school X.x

 

4.1ish Under Fremont?

 

i was in milpitas when it occured and definitely felt the shake, whole room actually shook but nothing crazy, probably lasted a few seconds.
