Seahawks' 12s: Fans Who Cause Earthquakes?

Seattle Seahawks fans are renowned as the '12s,' embodying the unofficial 12th player on the field. This designation highlights their immense contribution to the team's home-field advantage at Lumen Field, a stadium known for trapping sound and amplifying fan noise. This intense atmosphere has led to numerous penalties against opposing teams.

The fans' sonic impact is so significant that it has registered on seismographs on multiple occasions. Notably, during Marshawn Lynch's "Beast Quake" run in a 2010 playoff game, the fans' reaction caused a 2.3 magnitude earthquake. This reputation for extreme noise began at the Kingdome and continues to this day.

Originally known as the "12th Man," Seattle established a licensing deal with Texas A&M, who had trademarked the term. The Seahawks eventually adopted the simplified "12s" to maintain the nickname. The team first retired the No. 12 jersey in honor of its fans on December 15, 1984, solidifying their unique place in professional sports.
