4.6 is really small, what's the actual news here? Was it strangely shallow or something?

I was awake and it was definitely stonger than any I've experienced in my 3 years in SF

I'm pretty sure this is the closest epicenter to SF I've seen too (at least one that was noticeable)

Many of us on this website live in the bay area. The earthquake woke us up with a stern jolt and now you're witnessing a shared moment in the community as we try to drift back to sleep.

And that was just the automated response... it was downgraded to 4.3 an hour after the event.

4.3 will certainly get your attention if you're relatively close-by... but yeah, worth a "did you feel that?!" on the local news and not much more.

I would assume someone new to CA would find it concerning. It's fun to think about it - some Japanese people would move to CA just because of the more stable geology.

> The U.S. Geological Survey's most recent forecast, known as UCERF3 (Uniform California Earthquake Rupture Forecast 3), released in November 2013, estimated that an earthquake of magnitude 6.7 M or greater (i.e. equal to or greater than the 1994 Northridge earthquake) occurs about once every 6.7 years statewide. The same report also estimated there is a 7% probability that an earthquake of magnitude 8.0 or greater w…

There is an 80% probability that an earthquake of magnitude 8-9 will occur in the Nankai trough (massive subduction zone along the Pacific coast of Japan) in the next 30 years. Yes, you read that correctly. Eighty percent. It's almost a certainty.

San Andreas sounds like nothing by comparison, especially since it doesn't pose as much of a tsunami risk.

I was in a hot tub with friends! We wall went to Portola Music Festival and we were having a nice connective low key evening when this big shake surprised us!

Why would Japanese people move to CA for the more stable geology ?

Because there are no longer any other good reasons to move here.

Same. Been 12 years in SF and this was the strongest. We were awake as well so we felt the whole thing. I think I saw the walls move. Luckily it was short.

Contrast that with my experience in Ireland - 10 years and I heard thunder only twice, and saw a lightning strike only once. We sometimes get alerts due to some tropical storm that made its way up here, and the most we need to do is to collect our garbage bins and avoid biking because of the gusts.

There's no thunder in Ireland? Why?
