I understand there are some very active faults in the earth which move more than others but why is this? As a UK resident i recall 5 or so years back that we had a minor tremor which was huge news nationally. Why are some more active and violent than others and are earthquakes impacted or made more common by climate change?

The surface of the Earth is similar to large sheets of rock floating on top of a hot semi-fluid layer of magma. At the edges of these sheets is where most tectonic and volcanic activities happens because the sheets push and pull against each other. But, because they are rock they don’t slide smoothly. Instead they press together harder and harder until they over come friction and jump, causing an earthquake because of the sudden rapid movement.
