SOUNDS OF THE FUTURE?

Just about kick off time at the Super Bowl, Missouri as well as states
North, East and South of us heard a strange, loud sound. 

Here in St. Louis the noise reached us at dinner time and than it was
repeated before our lights went out leaving us in total darkness for a
short time.  The sound was described variously by people as a sonic
boom, a late afternoon truck delivery or a big highway accident, or
something being dropped on the roof.

According to Andrew Long researcher at the University of Toronto
Scarborough Climate Laboratory it was a "frost quake"  produced
by the zero and below degree climate we have been experiencing
since the first of the year. These temperatures cause the earth's plates
to move about and crash into each other creating odd sounds.

"Frost quake" or no, our lights came back on quickly, we went on with
our dinner and I was left with the strong feeling that this will not be the
last time we experience these "noises" and occurrences in the future.
