So, did anyone else feel the earthquake that struck Central Pennsylvania last night? I was checking my email on the computer in my basement family room at a little after midnight when I heard and felt a low, somewhat loud rumbling sound for about 4-5 seconds, then felt a "pressure wave" pass through me and then another second or two of rumbling. I emailed my friend Steve and asked if he felt it, but he was on the second floor of his house and didn't hear/feel anything. (I guess it was more pronounced from where I was sitting because I was in the basement, underground.) He immediately sent me THIS LINK on the U.S. Geologic Survey website. It was a 3.4 magnitude earthquake centered just north Landisville in Lancaster County! (CLICK HERE to see the maps.) Earthquakes in this area are uncommon. HERE'S another map of Pennsylvania showing previous earthquakes in an around the state. The last one I remember feeling was in 1980 or so when I was at Millersville State College. We Earth Science nerds were ecstatic! Pretty cool.
Did you feel it?
