North Nottinghamshire is the earthquake capital of the UK, but why is this?

The coalfields of Britain are frequently the source areas of small to moderate earthquakes and tremors.

Since the rapid decline of mining activity in the UK there has been a general decrease in the number of these events, however, events may still occur in these areas years after all mining activity has ceased.

The slip is triggered when the stress acting along the fault exceeds the frictional resistance to sliding.
