the ridge is a medium rate spreading center, moving outwards at a rate of approximately 6 centimeters per year. tectonic activity along the ridge is monitored primarily with the u.s. navy's sound surveillance system (sosus) array of hydrophones, allowing for real time detection of earthquakes and eruptive events.

the juan de fuca ridge is a mid-ocean spreading center and divergent plate boundary located off the coast of the pacific northwest region of north america. the ridge separates the pacific plate to the west and the juan de fuca plate to the east. it runs generally northward, with a length of approximately 500 kilometers (300 miles). the ridge is a section of what remains from the larger pacific-farallon ridge which used to be the primary spreading center of this region, driving the farallon plate underneath the north american plate through the process of plate tectonics. today, the juan de fuca ridge pushes the juan de fuca plate underneath the north american plate, forming the cascadia subduction zone.
