HARBOR EARTHQUAKE

I got a call from my girlfriend who was in Washington D.C. She started the call with  "I'm alright." O.K What happened? I replied. Didn't you hear about the earthquake about twenty minutes ago? she asked.  I had not though I was busy at the dock filling the water tanks and putting stuff away before heading out on a mini cruise. But, thinking about it more. I did feel it. Though from where I was down below it felt like some powerboat with some very heavy horsepower on board was starting up nearby. So I really did not notice it as an earthquake. Now if the harbor had started to empty out pre Tsunami like. Now that would have got my attention.
