SEISMICITY

Demo Video
What is Richter Magnitude/Local Magnitude?
What is ground motion?

During the hydraulic fracturing phase, we are monitoring induced seismicity using Traffic Light System (TLS) monitoring stations and submitting daily results to the regulator. On the Local Magnitude (ML) graph below we will be showing any seismic events over zero, which occur in our operational area, whilst we are hydraulic fracturing i.e. pumping fracturing fluid into the shale. In addition, after we have finished hydraulic fracturing i.e. are not pumping liquids, regulations state that any induced seismicity in our operational area, known as "trailing" events, should be below a level of 0.5ML and so we will also show any events that occur over this threshold. Hover the mouse over each icon on the graph to read more about each event.

The map below provides a view of any seismic events over the proceeding 24 hours (6am-6am) within the area of Cuadrilla’s seismic monitoring array (yellow boundary). The red boundary is the area within which Cuadrilla’s drilling and hydraulic fracturing operations are permitted.

Less than 0ML
(not shown)
Greater than 0ML but less than 0.5ML
Greater than or equal to 0.5ML

The map below provides a view of any seismic events in the wider area which have occurred since November 2017. This data is updated on a weekly basis by 10am every Monday. Seismic events outside the area of Cuadrilla’s seismic monitoring array (yellow boundary) are not attributable to Cuadrilla’s operations.

Please see the Daily Local Seismicity Map for events attributed to our operations within the TLS monitoring coverage

GROUND WATER

As a requirement of the Infrastructure Act 2015 Section 50, we are establishing a 12 month baseline of groundwater methane prior to hydraulic fracturing. Methane is measured every month within four boreholes (BH1, BH2, BH3 and BH4) within two geological strata, the Glacial Till and the Middle Sands. The baseline monitoring commenced in July 2016

SURFACE WATER

As a requirement of Cuadrilla’s permit from the Environment Agency, we are required to undertake surface water sampling. Samples are taken monthly from six locations including from Carr Bridge Brook and other small bodies of water near to the site. The graphs below show concentrations of diesel as this is the predominant chemical used on site. The baseline for surface water was established between May 2014-May 2015.

AIR QUALITY

Measurements for air quality around our site are shown at the graph below as gathered at four air quality monitoring stations around the site, measuring: Methane (CH4), Particulate Matter 2.5 (PM2.5), Particulate Matter 10 (PM10). Methane is monitored as a requirement of the Infrastructure Act 2015 Section 50. PM2.5 and PM10 are monitored every month to fulfil our obligations under the dust management plan agreed with Lancashire County Council (condition 32A). Measurements are taken once monthly. The baseline shown is the peak reading from the same monitoring locations taken during baseline readings from May 2014 – May 2015

NOISE

As a condition of Cuadrilla’s planning consent for the Preston New Road site, noise generation is subject to limits. Due to very high levels of background noise measured at Staining Wood Cottage (Location 1), a proxy location known as L2 was installed to take measurements of noise associated with the drilling rig. L2 takes measurements with less background noise and is closer to the rig. Therefore with L2 being closer to the rig and further away from the nearest residential receptor an additional 8dB scaling factor is added to the noise limits to account for the distance away from Staining Wood Cottage. For daytime hours (8am-9pm), the noise from the site at the L2 receptor shall not exceed 63 dBLAeq 1hr (level of noise averaged over an hour). For night-time hours (9pm-8am), the noise from the site shall not exceed 47 dBLAeq 1hr.

For any query related to noise levels due to Cuadrilla operations, we can refer to sound recordings to analyse whether noise is being caused by our operations or by background causes.

    What is ground motion?

    During the hydraulic fracturing phase, we are monitoring induced seismicity using Traffic Light System (TLS) monitoring stations and submitting daily results to the regulator. Recorded seismicity data is also shared with the British Geological Survey (BGS). The Local Magnitude (ML) graph refers to the magnitude of any seismicity detected above 0ML whilst we undertake hydraulic fracturing operations at Preston New Road. Ground motion examples on the graph were measured by the University of Liverpool and are normalised to a 2.5km distance so that they are more comparable to the depth of hydraulic fracturing operations at Preston New Road. Hover the mouse over each icon on the graph to read more about each event.
