Easter Keeps Rumbling

There are those that know where I live. There are others that do not, but if you take a good look at the information available, you know that there has been a whole lot of shakin' goin' on down here on the north side of the border. Last night, at 21:26 hrs local time, things started moving unexpectedly, again.

It is to the point that I can distinctly feel the three phases of a quake. This is due to the fact that I am about 100 miles from the epicenter. The first phase is like stomping. Loud stomping. This is where a huge amount of energy is, and in the original 7+ quake, the stomping was very loud and very sharp. You can hear it, thump - thump -thuMP - THUMP! Last night, the thumping was softer, and spread out a bit more (less energy) but the next two phases were vastly different.

The second phase, while distinct, did not really overlap the third phase last night. While it was distinctly violent and much stronger than Easter Sunday, the lack of overlap with the third phase prevented the toppling of my DVD tower, and nothing fell. It was also about 7-10 seconds shorter that the Easter quake. I wonder if there is value in examining the power distribution over the phases?

The third phase had the Foul Pole at the ballpark oscillating. The top of the pole was moving a much as a baseball diameter left and right, and this showed the power of the lateral motion that exists in the 3rd phase. Needless to say, the Umpire call time until the foul pole stopped moving. Oh, and in case you're wondering, there is only one foul pole at the ballpark. Which park is it?
