re: Why No More Earthquake Games?

I watched as well, thought I heard them say two things:

1) the seismographs are no longer operational, was some federally funded program in the ‘80’s.

2) the structure of the stadium back then was conducive for “vertical sound waves” or something like that and the since expansion has messed with that conducive setup up...whatever that means?

My own theory to add...no one in 1988 had their heads buried in their cell phones...all attention on the game.
