Game 1-4 Tunnel comps

During the 2023 season, the University of Utah Seismograph Stations installed a seismometer on the ground floor of the stadium to record ground shaking related to football games. Below is a summary of some recordings during the Cal game. The Utes started off slow and fell behind 0-7 at the end of the first quarter. However, the Utes owned the second quarter with a Ja’Quinden Jackson 3 Yd rushing touchdown at the 7:56 mark and a Sione Vaki 1 Yd rushing touchdown with 26 seconds left in the first half.

The Utes scored their third touchdown of the game with 9:11 left in the 3rd quarter when Bryson Barnes called his own number and ran 4 yards for the touchdown to put the Utes up 24-7.

Sione Vaki would add one more touchdown with 6:51 to go in the 4th quarter when he ran 72 yards to give the Utes a commanding 31-14 lead.
