Seems like a minor earthquake. Does it deserve top of HN?

It's gone sooner if you don't interact with the thread...

Isn't this the opposite of how it works? My understanding there is some algorithm that severely downranks threads that get a lot of comments in relation to the upvote count.

Is HN's content recommendation algorithm public?

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.

I’d say the same about East Anglia in UK, but in early ‘90s there was a tremor strong enough to notice. It was particularly strange then because you had to wait for the news on TV or radio to mention it.

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.

Why would Japanese people move to CA for 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 will occur in the next 30 years somewhere along the San Andreas Fault.

I question their research skills. I would avoid California if geology was my main motivator.

Not public, but some of the factors are listed here https://news.ycombinator.com/newsfaq.html (q2)

Japan is one of the most seismically-active areas in the world.

As a result, [modern] Japanese construction is incredibly resilient.

I've never been in Tokyo, during a strong quake, but I'm told the skyscrapers wave around like drunken dancers.
