N2  - This study examines the seismic hazard associated with shale gas exploration in the
UK, where such industrial activity is relatively new. We focus on the Preston New Road site in
Lancashire, where shale gas exploration occurred in late 2018. We compile, process, and analyse
ground motion data from nine seismometers located within 25 km of the site, which detected 57
exploration-related events with local magnitude (ML) range -0.9 to 1.6. We use the data to test a
number of pre-existing ground motion prediction equations for suitability to modelling potentially
felt events induced by UK shale gas exploration: (1) the Akkar et al. (2014a) equations for
European seismicity, (2) the Douglas et al. (2013) equation, developed for induced seismicity in
geothermal areas, and (3) the Atkinson (2015) equation, developed for induced seismicity in
eastern North America. We find that the Douglas et al. (2013) equation is the most suitable, at
least for the considered ground motion intensity measures, although it can over-estimate ground
motion variability. To understand if the ground motions differ relative to comparable motions from
other types of UK seismicity, we compare the ground motion intensities observed with those
recorded during a sequence of earthquakes near Newdigate, Surrey (believed to be natural) and
a sequence of events near New Ollerton, Nottinghamshire (induced by coal-mining). We find that
? depending on the intensity measure ? the intensities are similar to or higher than those of the
Newdigate sequence and are similar to or lower than those of the New Ollerton sequence.
