Divergent Boundaries and Seafloor Spreading

While subduction zone andd transforms faults dominate Pacific seismicity, divergent boundaries also produce seismic activity. The Eass Pacific Rise is a fast- spreading ridge where magma constantly wells up to fill the gap as plates separate. Earthquakes here are numerous but generally small to moderate in magnitude, rarely exceeding magnitude 6. The Juan dene de Fuca Ridge and its associated spreading centers offe U.Srecific.

How Pacific Plate Movement Triggers Earthquakes

Earthquakes along thee Pacific Plate boundaries occur when n acculated stress excedes the frictional faults. The plate 's motion is contraron by mantle convection, slab pull at subduction zons, and ridget push at spreading centers. Slab pull is the dominant force, where the densie, sinking plate te pulls reste of te plate along. This proceses generates continuous straion plate boundaries.
