“…A four-layer crustal model is described with the layers interpreted as, Upper Palaeozoic, Lower Palaeozoic, pre-Caledonian basement and lower crust. Crampin et al (1970) (1986), Davidson et al (1984) and Sola (1985). These data have led to the recognition of a four-layer upper crustal model, i.e.…”

The results of the Midland Valley Investigation by Seismology (MAVIS) are described. The experiment consists of three refraction profiles of between 80 and 100 km length across the Upper Palaeozoic basins of the Scottish Midland Valley. Three refractors are recognized, thus defining four upper crustal layers. The top two layers are interpreted as Carboniferous plus Upper Old Red Sandstone, and Lower Old Red Sandstone plus Lower Palaeozoic. The structure of the refractor, an unconformity, separating the two layers mirrors surface structure. Deeper refractors, associated with Midland Valley crystalline basement, show no correlation with surface structure. The MAVIS survey allows the refinement of earlier gross interpretation of upper crustal structure in the Midland Valley, but confirms the existence of anomalously shallow (6.4 km s–1) basement, and shows, in conjunction with results of previous work, that a large area of the central and southern Midland Valley is characterized by one velocity signature, probably indicative of a single terrane.

“…Seismicity levels are relatively low but there is a definite pattern within these low levels. An overall impression of the seismic activity can be obtained from the maps of Crampin et al (1976), which illustrate well the activity that exists along the continental margins both to the north (Norway) and to the south (France, Spain, Portugal). N o events are shown in Ireland or on the continental margin to the west of Ireland and Scotland.…”

SynopsisAt 10h 47m 59s GMT on April 13, 1980 a seismic event occurred at about 56·5° North, 10·5° West near the Hebrides Terrace Seamount. The seamount is believed to be an early Cenozoic volcanic feature (Buckley and Bailey 1975) and lies in deep water in the eastern part of the Rockall Trough. The event may have been either an earthquake or a large underwater explosion. The seismic evidence, based on recordings from stations in Scotland and Ireland, is that it was an earthquake. It is the first earthquake to be recorded from the contiguous continental margin to the West of Britain and Ireland.

“…In the late 1960s, an eight-station short period network of Willmore Mk III seismometers was installed in Central Scotland, with stations linked to Edinburgh by radio. This was LOWNET (Crampin et al 1970); it was initially conceived and developed by Stuart Crampin, for the study of local seismicity (Crampin 1967 unpublished). It also served as test-bed for the development of networks that could be deployed in more earthquake prone regions of the World (particularly Turkey, Iran and Papua New Guinea).…”

The work of John Milne, the centenary of whose death is marked in 2013, has had a large impact in the development in global seismology. On his return from Japan to England in 1895, he established for the first time a global earthquake recording network, centred on his observatory at Shide, Isle of Wight. His composite bulletins, the "Shide Circulars" developed, in the twentieth century, into the world earthquake bulletins of the International Seismological Summary and eventually the International Seismological Centre, which continues to publish the definitive earthquake parameters of world earthquakes on a monthly basis. In fact, seismology has a long tradition in Britain, stretching back to early investigations by members of the Royal Society after 1660. Investigations in Scotland in the early 1840s led to a number of firsts, including the first network of instruments, the first seismic bulletin, and indeed, the first use of the word "seismometer", from which words like "seismology" are a back-formation. This paper will present a chronological survey of the development of seismology in the British Isles, from the first written observations of local earthquakes in the seventh century, and the first theoretical writing on earthquakes in the twelfth century, up to the monitoring of earthquakes in Britain in the present day.
