Using the supplied referenced graphs, it shows that the beast quake measured 5mm in amplitude. If you bring up a richter scale calculator online and enter 5mm, it comes up as negative (-) 2.3. I think this means that not only was it not an earthquake, but it was off the scale of non-earthquakes. I don't think this article, or any of its sources, ever once notes the possibility of sound vibration (like standing near a concert speaker) as being a reason the stadium noise can be "felt" blocks away. I fear there is more hype behind this article than facts.StarHOG (Talk) 13:19, 20 March 2024 (UTC)Reply
