Earthquake!!

Well, now that I know where this earthquake has reached (All the way from Quebec and Ontario, to NY, Ohio, Michigan and Vermont), what was the size?

Edit: Claims on the magnitude of the earthquake are estimated between 5.5 and 5.7 on the Richter scale.

Edit#2: Confirmed at 5.5 magnitude (http://earthquake.usgs.gov/earthquakes/recenteqsus/Maps/US10/42.52.-80.-70.php).

The Richter Scale would estimate (Taken from Wikipedia):

5.0-5.9

Moderate

Can cause major damage to poorly constructed buildings over small regions. At most slight damage to well-designed buildings.
