These quakes occurred within a known cluster of faults near the Gorda Ridge and Blanco Fracture Zone, a seismically active region that experiences multiple events annually. Experts emphasize that activity in this zone is not directly linked to the nearby Cascadia Subduction Zone, a much larger fault system capable of producing catastrophic earthquakes.
