Here are the results from SOSN. Like I assumed, our closest seismometer read 0.1 mm/s, whereas that other big earthquake was about 1. Pembrooke looks like they got the maximum shot at 1 mm/s. This is definitely more in line with an M4.4.
Also I got 10 times more hits on my blog for 2007. Ah well, we can always wait for another one... :)
