Overview
- The Pacific Northwest Seismic Network installed six seismometers around Lumen Field to measure fan-driven ground motion for the divisional matchup with the 49ers.
- During Rashid Shaheed’s 95-yard opening kickoff return for a touchdown, the surge from Seahawks fans registered as measurable shaking on PNSN instruments.
- PNSN shared synced video of the score with the corresponding ground-motion trace, highlighting the real-time link between crowd activity and seismic signals.
- The Seahawks beat San Francisco 41-6 to reach the NFC Championship Game, with the atmosphere contributing to detectable vibrations captured by the new setup.
- The effort builds on the 2011 Beast Quake and prior playoff deployments in 2014, 2015 and 2017, serving both outreach and research into seismic waves.
