5.3
it's quite embarrassing that there has been such a fuss over what would be classed anywhere else as a small tremor
the thing didn't even wake me up and i'm a fairly light sleeper. The last "large" one we had though, 6 or so years back, that was a 4.8, but the epicentre was like 6 miles from my house so i did feel that one heh heh.
And as for the Oil building explosion, we felt that up here as well, 100 miles away, that was really quite scary though that was. The sky to the south was completely black! I'm surprised a lot of people didn't die in that thing.
