Little power flicker over the hill here, but that's about it.

Breaking news?

A 3.1 couldn't break much of anything.

3.1 Please. Let me know if it gets to 5 or greater. Guess you didn’t live there in 1989.

Which way? Toward SC?

Thanks. Reported my non-experience to USGS.

Wake me up when Governor Moonbeam’s office in Sacramento is on the beach.

Come on! 3.1!

3.1 and you post this as news? Are you joking?

This is a joke right?

[Henchster]

Your magnitude is way too low, or a big truck drove past your house. 3.1 is only detectable by sensitive equipment or skittish animals.

Pretty good rumble / booming sound.

The booming sound was surprising to me when I began experiencing earthquakes. I knew the earth shook, but it had never occurred to me that there was a rumbling sound to it as well.

I was at SRI then...at a meeting....place really shook up, ended up at the hotel with no lights, water, etc...fortunately the bar opened by candle light and stayed open all night.....

If we’re gonna start reporting every 3.1 in Calif., we won’t have room on the site for real news.

Been through many including ‘89 and larger in China - major aftershock of 7/28/76 Tangshan earthquake. But this is the first time I’ve literally been right on top of the slipping fault. It felt MUCH bigger than M3.1 would indicate - I would have guessed this to be 5 - 6 if it were 20 to 50 miles away. And this was only 1,500 feet deep, too — very shallow.

San Andreas, right?

Speaking of breaking. Michael Moore "breaking wind" would register more than 3.1
