SENSORS TO MEASURE‘ FAN QUAKES’ AT OHIO GAME

Ohio Stadium is sure to be rocking Saturday when Ohio State and Michigan take the football field, and geologists will find out just how much through the use of seismographs. Ohio State and Miami University professors teamed up with the Ohio Department of Natural Resources to devise the Fan Quakes Magnitude Scale and have planted sensors around the stadium this year to measure the seismic activity created by fans. The scale converts the shaking coming from fans into the perceived magnitude of a naturally oc- curring earthquake. Ohio State’s stadium in Columbus seats nearly 105,000. So far this season, the biggest quake came after Curtis Samuel’s touchdown catch at the beginning of the second half against Nebraska earlier this month. The shaking lasted more than two minutes and reached a Fan Quake magnitude of 5.2. Researchers said they expect fans at Saturday’s game between No. 2- ranked Ohio State and third-ranked Michigan to “take it to another level.”
