I heard the shaking lasted more than 5 minutes.
That's extremely long. One minute of shaking seems like an eternity. I can only imagine.
It's amazing how strong these are. Our local news is saying it'll even hit here (on a very very minor scale) around 8:30 a.m. They say it'll be just a riptide and/or undertow. The only precaution they will do is have people (surfers/swimmers) evacuate the water.
I still can't get over the 5 minutes of shaking.
