In August 2019 we reported on the occurrence of tremors after they led to operations being suspended at the only active shale gas site in the UK.
We used data from the British Geological Survey, which records seismic events induced by human activities.
And we annotated our chart to explain how events with a magnitude below zero are very small while those above 2.0 can be felt by people on the surface.
