Hubby and I just were out in the front courtyard having our coffee after lunch and we saw the coffee in our cups sloshing back & forth. There was a 5.8 earthquake hit at 11:40 am. in Chino Hills. It was a little rumble that built to a jolt and then a descending roll....about a total of 10 seconds. "Shake it up, baby!" It's been a while since I've felt any kind of shaking around here, even though small ones happen daily. It's just a kind of neat phenomena, when it doesn't escalate higher. Hopefully it was just a "burp" from Mother Nature and pressure has been relieved. Another exciting day in SoCal. My dog was acting weird, but she acts weird all the time, so she was no good for forewarning us. It made me just a tiny bit dizzy at the end of the 10 seconds or so.
