Tuesday's East Coast Earthquake

So..I've been trying to figure out why I've continued to think about my experience with Tuesday's east coast earthquake.  It's haunting me for some reason.  It was truly intense for me and for my daughter.  Please know, I've been through a San Diego earthquake which was an extremely bizarre experience because that was my first.  At San Diego, to which I had gone because of an educational conference, I was sitting on a folding chair on a concrete floor in a resort hotel when the floor became a leviathan.  I was sitting there and my sense of reality changed.  San Diego's experience went on for quite a while and I was really shocked or had gone into shock afterward for a few hours.  But even with that experience, it pales next to yesterday's earthquake.  Why?  San Diego's was a higher seismic measurement.  But my experience here was truly terrifying and I think I know why.  About 1pm my daughter, who had been working on the computer, came walking out onto the porch where I was sitting reading a book, and she say's "What's happening Mom? The house is shaking."  She had started to feel the movement inside.  Suddenly, while I sitting there and she was standing there, both of us staring out toward our yard, our house starting not just shaking but moving horizontally.  I watched my front porch columns go horizontally back and forth.  The sound was truly eery and I had a dreadful feeling.  My daughter and I grabbed each other's hands and held on as strongly as we could.  I said to her "This is an earthquake."  We literally watched our front lawn move sideways and up and down.  This is truly not an exaggeration.  Our experience went on for at least one full minute.  ...and I can't stop thinking about it.  Right afterward my daughter literally broke down and wept in shock.  I was in shock as well, but I had to be brave for her and just kept telling her that it was ok and everything was fine.  Those who josh about east coast earthquakes vs. west coast earthquakes really don't get it.  At least from where I was sitting, this was a truly intense and terrifying experience.
