I work on the top floor of a 6 story building and it felt like the building was bouncing up and down.
Woke one of my dogs up, which in turn woke us up. And I was out in the garage sanding when the aftershock came, I thought I was dizzy or something. Hope everyone is okay. Dan
Earthquake energy moves as compression, or p-waves through the earth, as well as s-waves, but we don't feel those typically. The stuff we feel on the surface is surface waves, also known as love or raleigh waves. Depending on the type of rock and intensity, I believe they can move 1-5km per second. As a geography major, geology is close to home, I'll ask my prof's tonight.
395 Miles from Where I am to O fallon thats just shy of an hour and half using 4 miles per second. What time is it in O fallon?
central kentucky felt it as well. it shook my brother's monitor on his desk and woke him up... i slept right thru it and we only live 4 miles away Glad everyone is alright
Ok I see you revised I re did the math and still looking at approx 1 1/2 at the fastest rate, any possiblity we'd feel that in Des Moines? I'm thinking if so might feel somthing as early as about 12:10 central... jsut having a little fun experiment here
That makes more sence it was posted here about 10:40 os that's more like it Dang never felt it in Des Moines, you are eastern IA right, ignore my pm
Glad everyone is ok....wait until Yellowstone wakes up, I wont feel it cause I will be "well done" but you guys towards the east will feel it and get ot see it coming!
