Earthquakes at divergent boundaries are a result of ‘pulling apart’ of the crust. this limits the potential magnitude of an earthquake.
Earthquakes at convergent boundaries are caused by compression. This means that any earthquake will only occur when the stresses are high enough to cause the rocks to ride over the top of each other. These earthquakes can reach much higher magnitudes
A transform fault is when 2 plates rub against one another along the plate edges. Like one moving north and the other south like the San Andreas fault in California
