“…by Aspinall (1990) who characterised the depths and fault rupture mechanisms of local, low magnitude (ML<3) seismicity about Hinckley Point, Dungeness, Wylfa and Trawsfynydd nuclear power stations. Interestingly, although Skipp (1988) found little evidence of risk to Hinckley Point from Tertiary relaxation of the Watchet-Colthrestone-Hatch thrust-fault in Somerset, planning application for the development of a pressurised water reactor was rejected as uneconomical in the 1990s.…”

This paper reviews the geophysics contributions of the QJEGH (and forerunner QJEG) over the last 50 years in support of engineering geology, hydrogeology and ground engineering. It includes a brief history of some world and national influences on the ascent of geophysics over this time. The fundamental objectives behind geophysical surveying and monitoring are recapped before presenting contributions, across a range of geophysical methods, within a framework of applications, originally devised by the Geological Society Engineering Group Working Party for Engineering Geophysics in 1988. Three quarters of the papers reviewed focused on UK geology. Seismic, electrical resistivity and thermal methods accounted for 60% of the contributions, with magnetic, gravity and seismicity accounting for a further 24%. Some contributions are highlighted in each of the applications sections; these were considered exemplars of good practice, of good data, or considered by the reviewer to be innovative (at the time). Tables classifying around 140 papers into geophysical themes will enable practitioners to utilise the Geological Society Online Lyell Collection to review appropriate geological and hydrogeological contexts for successful engineering geophysical applications in support of future engineering. 1. Review Structure The Quarterly Journal of Engineering Geology (QJEG) was established to support the Engineering Group of the Geological Society, with its first publication in 1967. In 2000, the name of the Journal was changed to the Quarterly Journal of Engineering Geology and Hydrogeology (QJEGH), providing more explicit recognition of the significance of hydrogeology to ground engineering. This paper forms part of a series celebrating the journal's contribution across a range of relevant subject areas during its first 50 years of publication. The series commenced with an overview paper that set out the origins, history and status of the journal (Winter & Bromhead, 2016) before taking a very brief look at the future. Covered here are the geophysical contributions made by the journal from 1967 to 2015, which can be used in conjunction with other papers dealing with connected topics, such as the reviews on: terrain evaluation, mapping and geological models by Griffiths (2017), aggregates and earthworks and geomaterials by Cassar & Standing (2017). Ascent of Geophysics over the last Half-Century Much of today's geophysics practice, has in part, been shaped by significant global events during the period covered by this review. Many geophysical techniques ascended to address the survey and monitoring demands in support of UK and overseas development. In the 1960s, during the Decade of Development, the Dept. of Technical Cooperation supported much exploration geophysical activity to assist the economic development in Kenya, Uganda and Nigeria after their independence from colonial rule. Regional mapping and exploration over depositional basins, fold belts, intrusions and faulted structures also aided surveys for coal and hydrocarbons,...

This paper presents a new interpretation of well-known outcrops on the south coast of the Bristol Channel at Watchet in southern England. It is prompted by our recent experience of high-quality three-dimensional seismic datasets from areas such as the Gulf of Mexico and Brazil which are dominated by salt tectonics. Previous structural interpretations of the Watchet outcrops were explained in terms of extension, inversion and strike-slip tectonics. We suggest that some of the structures in the area are not easily explained by any of these mechanisms, but that they are collapse structures associated with salt withdrawal and imply salt diapirism during the Late Triassic and Early Jurassic.
