1993 Earthquake Bulletin - British Geological Survey Seismology

1. INTRODUCTION1.1 The BulletinThe British Geological Survey's Seismic Monitoring and Information Service operates anationwide network of seismograph stations in the United Kingdom of Great Britain andNorthern Ireland. This area, including coastal waters, is covered within the limits of thedetection capabilities of the seismograph network and accuracy is extended through dataexchange with neighbouring countries. Seismic phase data, location details and magnitudesare presented in the Bulletin for all earthquakes detected and located by BGS during 1993together with maps showing the larger magnitude events since 1979 (ML2 2.5) and since1970 (ML2 3.5).1.2 Summary of 1993 seismicityThere have been 358 earthquakes located by the monitoring network in the year, with 39 ofthem having magnitudes of 2.0 or greater. Six in that magnitude category are known to havebeen felt together with a further seven smaller ones, bringing the total to 13 felt earthquakesin 1993.The largest onshore earthquake of the year occurred in Grange-Over-Sands, Cumbria, on 26June with a magnitude of 3.0 ML and a felt area of 2700 km2. A macroseismic surveythroughout the region showed that it was felt in the epicentral area with a maximum intensityof 5 MSK (just below the damaging level). The focal mechanism interpretation shows twopossibilities; strike-slip with a small component of reverse faulting or reverse faulting witha small component of strike-slip faulting. Further details of this event are given in AppendixAl.The largest felt offshore earthquake in 1993, (magnitude 4.0), occurred on 7 July and was feltat the Gorm hydrocarbons field. The felt reports described "a shuddering" on the Gormcomplex and on a nearby standby vessel resulting in a production stoppage of 2 hours. Itlocates in a similar area to the magnitude 4.0 ML event on 10 June 1985 which was felt onthe Gorm and Tyra platforms and on a standby vessel.A swam of events occurred 10 km south of the isle of Arran with magnitudes ranging from0.9 to 1.7 ML, on 6 and 7 January. Later in the year (13 June and 8 August), two eventswith magnitudes of 1.3 and 1.6 ML were located in the same general area as the swarm.On 29 June, a small event (magnitude 2.0 ML) was located in the Potteries, Stoke-on-Trent.It was felt in the Talke Pits area and it was reported that unstable objects were overturnedindicating an intensity of at least 5 MSK.Near Coniston in Cumbria, a magnitude 1.5 ML earthquake was detected on 8 July 1993. Asingle felt report was received from the village of Kirkby-in-Fumess describing "a noise likea heavy lorry passing outside". It locates some 18 km from the Grange-Over-Sands earthquaketwo weeks before.A series of 22 events near Mallaig in the north-west of Scotland was detected in August and1

September with magnitudes ranging from -0.2 to 2.7 ML. The largest was felt with intensitiesof at least 3 MSK (catalogued as 3+) in the town of Mallaig where residents reported a noise"like a small blast". The event locates in the same general area as the magnitude 3.7 MLMallaig earthquake of 1 December 1985 which was felt with intensities up to 4 MSK.Three small events occurred near Ludlow in September with magnitudes of 1.8, 2.3 and 1.6ML, They all locate at a mid-crustal depth of around 14 km. A fault plane solution of thelarger event (2.3 ML) shows strike-slip faulting with a small thrust component (AppendixA2).In September, 11 small events with magnitudes ranging between -0.2 and 0.6 ML werelocated near to Johnstonebridge, Dumfries and Galloway. None were reported to be felt.They locate at depths of between 3.9 and 5.0 km in the same general area as the feltJohnstonebridge earthquake on 27 February 1992 (magnitude 2.7 ML).A magnitude 2.3 ML earthquake was felt by a few people in Betws-y-Coed and Nantbh,North Wales on 11 October 1993. It located at a depth of 9.3 km and the fault plane solutionshows dominant normal faulting with a small component of strike-slip faulting (AppendixA3).On the Lleyn Peninsula of North Wales, five events with magnitudes ranging from 0.0 to 1.4ML were located at depths between 20.7 and 23.4 km and form part of the earthquake serieswhich was detected following the magnitude 5.4 ML earthquake of 19 July 1984.Throughout the year, 89 small events were located near the village of Constantine in Cornwallwith magnitudes ranging between -0.8 and 1.8 ML. None were reported to be felt. They formpart of the continuing series which has been instrumentally recorded since 1981 and whichhas produced five felt earthquakes.Some 53 coalfield events with magnitudes ranging between -0.2 and 2.4 ML have beendetected in 1993, six of which were felt. Thirty of them were located in the Clackmannanarea in the central region of Scotland, where 3 events were felt by local residents in thevillage of Forest Mill; the largest (1.6 ML) had an intensity of at least 3 MSK.Near Ranskill, Nottinghamshire, a magnitude 2.2 ML coal-mining event was detected on 11November. It was felt strongly in the village of Ranskill where residents ran out of theirhouses into the streets, indicating an intensity of at least 5 MSK. The largest coalfield eventduring the year had a magnitude of 2.4 ML but was not reported to be felt.2

3. THE BGS UK SEISMOGRAPH NETWORK3.1 InstrumentationA standard seismic network consists of up to seven 'outstation' vertical seismometersradio-linked over distances of up to 100 km to a central site where the data, along with thatfrom a local 3-component set of two horizontal and one vertical seismometers, are recordedon magnetic tape by a Geostore recorder. Tapes are dispatched, usually once per week, toEdinburgh for analysis.A more detailed description of the system is given by Browitt et a1 (1985) and the responseof the system is described by Turbitt and Stewart (1982).At some locations, on-line paper chart recorders display three channels to permit rapidinvestigation of reported felt tremors. At other stations, low-gain vertical seismometers extendthe dynamic range (by 34 db) of the system to stronger motions, and low frequencymicrophones are used to aid the discrimination of sonic booms. In addition, strong motionaccelerometers installed at several locations (near Hunterston, Cornwall, Chapelcross andJersey) record accelerations up to 0.1 g.At locations shown in red on Figures 1 and 2 the seismograph stations are recording ontodigital event triggered recorders (SEISLOG). These are designed to trigger on events andwrite to a computer disk which is accessed from Edinburgh via a modem. Each morning,automatic data transfers are made to the Edinburgh VAX computer and the events areanalysed during that day providing a rapid response for location and magnitude calculations.SEISLOGS have the advantage over the Geostore system of providing a wider dynamic range(72 db), a bandwidth of up to 40 Hz and the capacity for 16 seismic channels. The systemalso has the facility to auto-reboot in the event of mains power failure and this normally takesthree minutes once power has recovered.Improvements in geographic coverage of the UK are described in Turbitt (1983, with morerecent developments in Walker and Browitt (1994), in press. In December 1993, 68% of the128 stations were being recorded on a rapid access SEISLOG system.3.2 Detection ThresholdThe detection capabilities of a network depend upon station distribution, instrument sensitivityand background noise levels. For the BGS UK network, the lower limit of sensitivity isgoverned by the background noise level. The contours in Figure 2 illustrate the lowerthreshold magnitude for an earthquake to significantly exceed 4 nanometres of noise (average)at 10 Hz on at least four seismographs. Noise sources such as wind, waves, traffic andlivestock vary considerably with time (typically 0.5 to 15 nanometres, at 10 Hz) causing themagnitude thresholds to increase or decrease. In conditions of high noise, 0.8 ML should beadded to the contour values.The detection contours in Figure 2 hold true only if all stations are continuously monitoredand this is not always the case. Small events in unmonitored areas may then go undetectedunless they are felt and reported to BGS by local inhabitants. The detection capabilities bythis process are strongly dependent on population density.4

4. HYPOCENTRE PARAMETERS AND THEIR ERRORS4.1 Epicentre LocationBy accurately timing the signal onsets at a minimum of three stations, a location can be foundfor an earthquake which satisfies the observed pattern of arrivals. Instrumental locations inthe bulletin were obtained using the computer program HYPO71 (Lee and Lahr, 1975) whichiteratively adjusts a trial hypocentre (latitude, longitude, depth, and origin time) until theobserved and computed arrival times coincide closely.The accuracy of locations is dependent on distances from the closest stations, the distributionof the stations around the epicentre, the resolution to which signal onsets can be timed fromthe records, and the accuracy with which the seismic wave velocity through the earth can bemodelled.The velocity models used for the location of events in 1993 are given in Table 6 and werederived from a series of refraction profiles traversing Britain, LISPB (Bamford et al, 1976;Bamford et al, 1978; Assumpcao and Bamford, 1978 and Bott et al., 1985).4.2 Depth DeterminationThe accurate determination of earthquake depth presents a more difficult problem, mainlybecause phase arrival patterns at the seismographs can still be satisfied for a large range ofdepths merely by adjusting the origin time to suit. Constraints on the depth can usually onlybe imposed when a station is very near the epicentre and even then the accuracy depends onthe velocity model.The best depth determinations have been obtained when a series occurred almost beneath anetwork. For events at larger distances, and where the error columns (ERH and ERZ), in thetables, are blank, the depth errors can be up to tens of kilometres. The quality factor of theevent, as listed in the tables (SQD), is an indication of the depth error. As a general guideonly, A*A, A*B, B*A and possibly B*B class events, have reliable depths.4.3 Seismicity DistributionOwing to variability in the earthquake detection threshold, which is governed by ambientnoise conditions and the geometry of the observing network (see 3.2), the bulletin is biasedtowards certain localities. In order to present a consistent picture of UK seismic activity,earthquakes with magnitude 2.5 ML or greater, in the period 1979 to 1993, have been plottedin Figure 4. The data set is considered complete for these magnitudes in all localities of theonshore area. Seismicity for the period 1970 to 1993 is shown in Figure 5 with a thresholdmagnitude of 3.5. This is the period covered by BGS instrumentation which in the early years,only consisted of the network around Edinburgh (LOWNET) and Eskdalemuir (ESK) and astation near Kyle of Lochalsh (KYL). The data set is likely to be complete for suchmagnitudes.5

4.4 MagnitudeAll earthquakes in the bulletin have been assigned a local magnitude (ML) as defined byRichter (1 935):ML = log,, (NAo)where A is the maximum deflection (centre to peak in mm) registered by the earthquake ona Wood-Anderson seismograph and Ao is that for a 'standard' magnitude zero earthquake atthe same distance. The Ao term is thus a distance correction factor tabulated by Richter to200, and later 600 km. Although Richter intended his method to be an approximatequantification of earthquake size and his attenuation term, Ao, strictly only applies toCalifornia, the formula is still used world-wide today. The ML magnitudes in this bulletinhave been calculated according to Richter by converting the output of the BGS instrumentsto an equivalent Wood-Anderson deflection. Ideally, the measurements are made on twohorizontal instruments and averaged but, if this was not possible, the mean of the magnitudesfrom a number of verticals has been used. Ground motion registered at a seismograph varieswith site conditions, direction from the earthquake, and the nature of the ray path.Consequently, it is important to take the mean from a good distribution of stations. Theresulting errors on magnitudes quoted in the bulletin will normally be less than 0.4 ML.4.5 IntensityIntensity is a measure of the effect of the shaking on people, structures and objects. Itdecreases with distance from a maximum value (Io) usually found close to the epicentre. Themaximum felt intensity is quoted, where known, on the MSK scale (Ad Hoc Panel, 1981).5. BULLETIN CONTENT AND COMPLETENESS5.1 The geographical areaThe bulletin covers all of the UK land mass and its coastal waters including the North Seato 800 kmE and 1400 kmN.5.2 Events includedAll events believed to be due to true tectonic origins have been included, that is, eventscaused by natural stresses within the earth.Coalfield events are also included. These are small events occurring near coal workings whichare believed to be caused by the redistribution of stress as the coal is extracted and, in somecases by collapse in old workings. They are indicated by C/F in the comments column ofTables 1, 2 and 5.Acoustic disturbances, such as sonic booms from supersonic aircraft, are included when theyare felt. The air-borne waves are readily identified by their slow travel time across an arrayor by their signature on a microphone but they are frequently reported by local people as6

small earthquakes. They are indicated by 'SONIC' in both the locality and comments columnof Tables 1 and 3. In 1993, nineteen sonic events were reported felt and all were detectedby the UK network.Significant non-natural events which received Media attention and felt explosions are alsoincluded in Tables 1 and 3. The felt explosions are indicated by 'EXPL' in both the localityand comments column. In 1993, five felt explosions were detected and a further six werereported in local newspapers.5.3 Events excludedEvents that are known, or suspected to be of explosive origin, are excluded from the bulletin.Explosions due to quarrying, mining, weapon testing or disposal, naval exercises, geophysicalprospecting and civil engineering are all excluded where possible, unless reported to be felt.Unfortunately, identification by record character, location and time of occurrence is notalways conclusive and some man-made events may have been included in the bulletin or,more rarely, a small natural event may have been excluded.5.4 CompletenessThe contours of detection threshold in Figure 2 show that the whole of the UK is covered bythe seismograph network for approximately magnitude 1.5, and above, at times of averageambient noise levels. High noise levels may cause this threshold to rise to about 2.3.Normally, however, an earthquake of this size would be felt, if not detected, in the areas ofpoorer instrumental coverage. The bulletin can, therefore, be assumed to be complete for allearthquakes of magnitude 2.3 and above.ACKNOWLEDGEMENTSWe are indebted to States of Jersey Meteorological Office, the Universities of East Anglia,and Leeds, and many individuals who assisted with station operation; to P H 0 Henni andR M W Musson, who supplied information on macroseismic data; to J Exton and J A Boltonfor the data presentation software and to the BGS Operations section: S N Morgan, D LPetrie, D A Stewart, R M Young and P S Day.The work was supported in part by:AEA TechnologyBritish Nuclear Fuels plcDepartment of Economic Development (N Ireland)Department of Trade and IndustryDepartment of the EnvironmentJersey New Waterworks CompanyNatural Environment Research CouncilNIREXNuclear Installations InspectorateRenfrew District CouncilScottish Hydro-Electric plcScottish Nuclear LtdWelsh Office

Seismograms of the event from BGS monitoring networks in the Bordersand North Wales are shown in Figure A1 .l . The fault plane solution is poorly constrained,but three main groups of planes can be seen in Figure Al.2. The most prominent group ofplanes (55 in total) represents strike-slip faulting with a small component of reverse faulting,and movement on either a plane striking N-S and dipping steeply to the west or a near verticalplane striking E-W. A second group of planes represent dominant reverse faulting with asmall component of strike-slip faulting, with movement on either a N-S striking plane dippingto the west or a NE-SW striking plane dipping to the SE. The final group of planes alsorepresents dominant reverse faulting with a small component of strike-slip faulting, withmovement on either a plane striking N-S and dipping to the east or a plane striking NE-SWand dipping to the NW. All three mechanisms are consistent with a NW-SE maximumcompressive stress direction. A macroseismic survey was undertaken for this event and over900 responses were received. The event was felt over an area of 2,700 km2, with a maximumintensity near the epicentre of 5 MSK (Figure A1.3).

They all had mid-crustal depths of around 14 km. Seismograms of the earthquake fromthe BGS networks in Hereford and North Wales are shown in Figure A2.1. The fault planesolution (Figure A2.2), shows strike-slip faulting with a small component of thrust faultingand is in agreement with a NW-SE maximum compressive stress direction observed forBritain .

No macroseismic survey was initiated. Seismograms recorded bythe BGS networks in Hereford and North Wales are shown in Figure A3.1. The fault planesolution (Figure A3.2), although apparently rather poorly constrained by stations to the northeast, has been improved by the use of five amplitude ratios, and shows dominant normalfaulting, with a small component of strike-slip faulting. The P and T axes, while nothorizontal, show general agreement with the directions of others obtained from fault planesolutions of previous North Wales earthquakes and with those from the remainder of GreatBritain.
