Alki Beach in Seattle faces significant geological hazards. It is located near the Seattle Fault Zone under Puget Sound, which caused earthquakes and tsunamis. Loose sediment deposits from glaciers covering the underlying terrain can slip and slide during seismic events, amplifying tsunamis. The region is prone to landslides due to steep slopes and loose, saturated soil from glacial history. Visiting Alki Beach shows evidence of unstable land through sinking poles and cracks. Reckless deforestation has caused landslides in the past.
