1) MORs?
1) Heat flow leads to the eruption of pillow lava. Rising magma causes shallow focus vibrations (Low Richter).
2) Axial Rift?
2) Shallow quakes, subsidance along fault causes quake (Low Richter).
3) Transform Fault?
3) As oceanic spreads away from the MOR, horizontal movement of faults cause quakes  - Moderate to Shallow).
4) Subduction Zones?
4) Oceanic plate subducted under the continental - Shallow to Deep quakes. Start of the zone is the trench, end is where the plate is melted.
