      As a former Californian, the magnitude scale goes something like this:
      3.5 - Huh, what? When did that happen?
      4.0 - Ehh, something moved slightly...
      4.5 - Oh, I actually felt that one there.
      5.0 - Heh, that actually qualifies as an earthquake.
      5.5 - Oh boy, we are starting to shake pretty good. Stay away from the glass, this one might be a little rough.
      6.0 - Find a doorway quick and hang on! This one will be rough.
      6.5 - Oh crap, duck and cover! 20sec of destruction, 2 weeks of "The Big One is coming! Are you prepared? Will you die?!" news stories.
      7.0 - Oh $h17!!! This one is going to hurt.
      8.0 - Wait, what? You mean the Big One is real?

      Scale +/-0.5 depending on where you are located in California (i.e. Bay area vs. Inland empire). A 4.0 ranks as barely noticable ...

    Hai guys I just saw a bird fly past my window at 2015-05-03 22:32:45 UTC, followed by a moth seven minutes later.

    I looked out the window today in Seattle and saw what looked like water falling from the sky. It was collecting on the ground in puddle and making cars wet. I just consulted the NOAA website and confirmed that there was indeed "precipitation" in the Seattle area. Stay tuned for updates.
