The Kego Fault Zone, which runs through the center of Fukuoka, is believed to face a similar risk from an unruptured section. The 2005 Fukuoka Prefecture Western Offshore Earthquake occurred in the northwestern part of the Kego Fault Zone, but the southeastern section did not move and remains unruptured. The government's Headquarters for Earthquake Research Promotion classifies both the southeastern section of the Kego Fault Zone and the Hinagu Fault Zone as S-rank, its highest danger category. "People should understand that the Kego Fault is now in a state where it has been subjected to stress. Fukuoka Prefecture has estimated the damage that could occur if an earthquake originates in the southeastern section of the Kego Fault Zone.
