Here is Cuadrilla's statement in full:
Latest update about today’s seismicity at Preston New Road.
We can now confirm the event detected at 8.30am in the area of our exploration site in Preston New Road, near Blackpool, was magnitude 2.9 on the Richter scale.
We appreciate this this has caused concern for local people and by way of reassurance it is worth noting that this event lasted for around a second and the average ground motion recorded was 5mm per second. This is about a third of that permitted for construction projects.
As previously stated, we were not operational this morning and no hydraulic fracturing has been carried out this weekend.
We are working with the team of regulators who intensely monitor our activity at Preston New Road to investigate the event and will provide more updates in due course. Hydraulic fracturing operations will remain suspended during this time.
We have verified that the well integrity is unaffected.
