The Pacific Northwest Seismic Network is installing monitors at the Clink to measure for potential beastquakes in Saturday's game (there is an annotated breakdown of the 2011 event on the linked page). Perhaps they will display realtime info on the screens, which could incite the audience to make even more noise.
An even noisier crowd ain't no way to show dem southern boys any decent hospitality. I wonder if all that noise will one day backfire against Seattle's own players. I was at a KISS concert in their 70's heyday the overly noisy crowd kind of wrecked parts of the show for me. I came to actually hear music for a change.
