#103Just felt it in Toronto on the 9th floor. I was the only one that actually tried to leave the building. That worries me about what people would do in bigger earthquake.
Felt it and seen it in Toronto, on the 23th floor. My chandelier was swinging moderately.

#104Felt it in Foggy Bottom. At first I thought it was the AC or jackhammering. I'm happy I don't have to experience this often, like in California.
I've lived in the Bay Area for ~24 years and I've actually felt maybe 4. I'd hardly call that often.

#105Not to spoil the fun, but isn't this the sort of stuff that leads down the slippery slope to reddit's front page? I understand that this affects large numbers of HN users, but so do lots of things that are very far from the tech/business/coding core of this site. Besides, there are a million places to go for this info.

#106Felt it in Toronto
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?
Well, let's suppose you're in Trenton, NJ (since you didn't specify). The distance between Trenton and Toronto is 546 km. If it took 10 seconds to travel there, then it was traveling at 54.6 km/s, or 196560 km/hour. For comparison, the speed of sound is 340.29 m/s, or 0.34029 km/s; that means that the shockwave travelled at Mach 160.
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.

About 10 years ago during a minor earthquake in the California Bay Area, I happened to be on the phone with my girlfriend at the time who was in Mountain View, I was in San Jose. The conversation went something like:
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.

About 3.5 km/s - if poorly drawn comics are to be believed.

#109It was centered 1 mile away from the Lake Anna nuclear reactor. Fingers crossed that their safety record was top notch... I can't reach anyone down there to check.
Latest news is both at-risk reactors automatically shut down and crews are doing walk throughs.

#110Shook us up nice in Boston as well.
(Yes, I reported to USGS) In the 3rd floor of a ~20 floor Boston office building I felt two mild tremors around 1:55pm, maybe 10 seconds each with a 10-second pause in between.
I also reported to the USGS. I'm on the 14th floor of a building in Kendall Sq (Cambridge) and we shook for probably 45 seconds.
