Because the subduction of the Pacific Plate is very near to centres of human population at the edge of a continental plate, whereas the seafloor spreading in the Atlantic is in the middle of the ocean, far away from human habitation.
Subduction zones are where the seafloor is forced under continental plates.
seafloor spreading
The typical rates of seafloor spreading is 5 centimeters per year. Seafloor spreading is a process that occurs at mid ocean ridges.
The Mid Atlantic Ridge
The Atlantic Ocean is growing due to seafloor spreading. The Mid-Atlantic Ridge runs down the center of the Atlantic, where new oceanic crust is continuously formed as tectonic plates pull apart. This process contributes to the widening of the Atlantic Ocean.
Seafloor spreading and subduction
Subduction zones are where the seafloor is forced under continental plates.
seafloor spreading
New oceanic crust is being created at seafloor spreading zones, and crust is alternately being subducted and destroyed at subduction zones.

The Pacific seafloor formed at a faster spreading rate than the Atlantic seafloor.
