GEL has installed a network of seismometers around the United Downs site, which will be relocated and expanded for future sites, as necessary. This network is continuously providing real-time data and can detect and accurately locate both large and small seismic events. If a seismic event is detected, GEL and seismic specialists will quickly be able to work out where it happened. Depending on how far it was from the site, and the type of work being carried out at the time, it will be possible to determine whether it was the result of GEL’s activities or not.

In fact, the seismic monitoring equipment can detect events that are hundreds of times too small to be felt at surface and this monitoring will be done on a continuous basis. GEL has a contract with a local seismic specialist who will provide accurate measurements of any seismic activity and will also pass the data to BGS for them to interpret. A seismic management procedure is in place so that GEL can work with the relevant authorities. The team will also post relevant information on their social media.
