Seismicity at Preston New Road, October 2018

Seismic trace

Since hydraulic fracturing started at Preston New Road, near Blackpool, earthquakes have been detected close to site.

We publish detected events on our website page earthquakes around the British Isles in the last 100 days. Magnitudes are local magnitude (ML) and are calculated to one decimal place, as is standard practice in earthquake seismology.

The BGS has deployed additional seismic sensors across the north of England. This denser network allows us to detect smaller earthquakes than we are typically able to do.

The Oil and Gas Authority (OGA) has strict controls in place to ensure that operators manage the risk of induced seismicity. This includes a requirement for operators to control and monitor the fracturing process and assess the risk of induced seismic events.

The BGS is not a regulatory body. Our role is to provide impartial data. Current regulations require operators to stop hydraulic fracturing if an event with a magnitude of 0.5 ML or above occurs during operations. It is the responsibility of the operators to carry out real-time seismic monitoring and any decision to stop will be based on the information they provide rather than by the BGS.

Our seismic monitoring provides an impartial source of earthquake data. Data from our stations are viewable on the real-time seismograms page of our website.
