COLUMBUS, Ohio (AP) — Geologists measuring vibrations caused by boisterous Ohio State football fans say the Buckeyes' game-winning touchdown in double overtime against rival Michigan had Ohio Stadium rocking more than any other time this season.

Ohio State and Miami University professors teamed up with the Department of Natural Resources to devise the "FanQuakes Magnitude Scale." Using measurements taken around the stadium, it converts the shaking from fans into the perceived magnitude of a naturally occurring earthquake.

Before last Saturday's game, the high point was after Curtis Samuel's touchdown catch against Nebraska. It reached a FanQuake Magnitude of 5.2.

Researchers say the opening kickoff with Michigan topped that at 5.27, and the magnitude grew after a couple of interceptions. It rated 5.7 during J.T. Barrett's first overtime touchdown, and 5.79 after Samuel's game-winning score.
