GEOLOGY

Detailed explanation-1: -At divergent plate boundaries, earthquakes tend to be weak and shallow.

Detailed explanation-2: -Mid-ocean ridges and transform margins have shallow earthquakes (usually less than 30 km deep), in narrow bands close to plate margins. Subduction zones have earthquakes at a range of depths, including some more than 700 km deep.

Detailed explanation-3: -Shallow, low-magnitude earthquakes commonly occur at divergent plate boundaries. Earthquakes at divergent plate boundaries are distributed with predictable locations and depths. Earthquakes at divergent plate boundaries occur as new crust is created and other crust is pushed apart.

Detailed explanation-4: -Transform boundaries Most transform faults are found on the ocean floor. They commonly offset the active spreading ridges, producing zig-zag plate margins, and are generally defined by shallow earthquakes.
