If anyone was awake at 1:30 this morning, they might have been shaken up a bit -- literally. There was a 4.2 earthquake, not very deep in the ocean floor (which dampens the effect if they are at greater depth), only 60+ miles north of us. If you want to find out more, the web site is http://earthquake.usgs.gov . Note that there is no 'www' in the web address. Once on the site, you'll find a global map, with a special insert for the Puerto Rico etc. area.
