Workers on a North Sea oil rig felt ‘shaking’ after a 4.2 magnitude earthquake occurred.
The BGS reported that the quake was 10km deep and was awarded a level three intensity rating on the European Macroseismic Scale.
Tremors of this intensity are defined as “weak”, causing light vibrations and trembling that may be noticeable in a few homes.
It is estimated that around 900,000 earthquakes happen annually, most rarely causing damage and only a fraction of the tremors felt on the mainland.
