A colleague (we're in NJ) was on the phone with Toronto, and the Canadians felt it a short time (10 seconds?) after we did. How fast do these things travel?
GF: "Oh! There's an earthquake!"
Me: "What, no there isn-- Oh wow, there's an earthquake!"
(few seconds of shaking)
GF: "Okay, it's over"
Me: "No it isn't, I stil feel-- Oh yeah, it's over!"
I'd estimate the delay to have been ~2-3 seconds over ~20 miles -- but I don't remember where the epicenter was, or how deep the quake was.
Of course, this assumes that it was traveling over the surface, so it's really lower than this, but I'm unsure of how much. From what I'm seeing, the fastest earthquakes generally travel about 13 km/s, so this may be way high.
