1. INTRODUCTION

1.1 The Bulletin

The British Geological Survey's Seismic Monitoring and Information Service operates a nationwide network of seismograph stations in the United Kingdom of Great Britain and Northern Ireland. This area, including coastal waters, is covered within the limits of the detection capabilities of the seismograph network and accuracy is extended through data exchange with neighbouring countries. Seismic phase data, location details and magnitudes are presented in the Bulletin for all earthquakes detected and located by BGS during 1995 together with maps showing the larger magnitude events since 1979 (ML2 2.5) and since 1970 (MLr 3.5). All felt areas are quoted in km2, and are for the area enclosed within isoseismal 3 EMS (European Macroseismic Scale, Appendix C).

1.2 Summary of 1995 Seismicity

There have been 225 earthquakes located by the monitoring network in the year, with 38 of them having magnitudes of 2.0 ML or greater. Of these, nine are known to have been felt, together with a further twelve smaller ones, bringing the total to twenty one felt earthquakes in 1995.

The two largest onshore earthquakes during 1995 had magnitudes of 2.7 ML. The first occurred at Reedham in Norfolk on 1 January. No felt reports were received and it is thought that this may be due to the depth of occurrence (6 km) or time of year. The other, occurred near Aviemore, Highlands, on 28 August and was felt in Boat of Garten, Aviemore, Grantown-on-Spey, Carrbridge and many of the surrounding villages. Felt reports described "a bang, a rumble, the building shaking" and one person reported that "ornaments moved and glasses shook"; a few reports of minor damage were also received. The earthquake was felt over 1300 km2 (Isoseismal 3) and located in an area where no previous seismicity had been recorded. A macroseismic survey throughout the region showed that it was felt in the epicentral area with a maximum intensity of 4 EMS (Appendix AI).

The two largest offshore earthquakes, with magnitudes of 3.6 ML, were located in the northern North Sea on 28 June and 13 November.

A swam of earthquakes was located in the Stoke-on-Trent area in February. They had magnitudes ranging between 1.4 and 2.5 ML and six were felt by local residents. The largest (magnitude 2.5 ML, Appendix A2) was felt throughout the Stoke-on-Trent area, with intensities of at least 4 EMS in the epicentral area. The felt area for the event was 720 km2 (Isoseismal 3). From the available data (nearest BGS station some 25 km away), many of these events had characteristics typical of natural earthquakes but with some showing characteristics typical of mining-induced earthquakes. Similar swarms in the area were detected in the mid 1970's, early 1980's and early 1990's.

Near Newcastle-Under-Lyme, on 22 February, a magnitude 2.3 ML event was felt by local residents in Newcastle-Under-Lyme, Madeley and Stoke-on-Trent. They reported strong shaking and the felt area was calculated to be 200 km2 (Isoseismal 3). The signal recorded by the BGS Keyworth network showed that the source was shallow (presence of surface

1 waves) and it is thought to be related to the nearby mines in the region. Two other shallow events, which were located in the same area, occurred on 14 October (magnitude 1.5 ML) and 29 November (magnitude 2.0 ML); the latter was felt with intensities of at least 2 EMS.

On 11 March, in the Irish Sea, a magnitude 2.3 ML earthquake was located 12 km east of Ramsey, Isle of Man. It was not felt and locates in an area where no previous seismicity has been detected.

Near Cardiff, a magnitude of 2.2 ML earthquake was detected on 13 March. No felt reports were received. It located in an area where no other seismicity has been detected in the past.

In the southern North Sea, on 2 May, a magnitude 3.4 ML earthquake was located 65 km offshore of Great Yarmouth, United Kingdom, in the south-west part of the Lemen gas field. It located in an area which has had a history of earthquakes and in the same general area as the magnitude 5.1 ML earthquake of 9 February 1958, which was felt with an intensity of 5 EMS.

In the English Channel, 55 krn south of Plymouth, a magnitude 3.1 ML earthquake was located 17 August. It occurred in an area with no recent history of seismic activity. Although events of this size are normally felt, no felt reports were received.

Near Horndean, in Hampshire, on 9 September, a magnitude 2.5 ML earthquake was located at a depth of 9.3 km in an area with no previous recent seismicity. Despite its magnitude, no felt reports were received.

Two events some 9 km south west of Mansfield on 11 October with magnitudes of 1.9 and 2.4 ML; the latter was felt by local residents in South Normanton with intensities of at least 3 EMS. These events occur at depths of 6.5 and 6.8 km and the absence of surface waves suggest that they are not related to coal-mining activity.

Twenty events in the northern North Sea, with magnitudes ranging between 1.3 and 3.6 ML were located by the BGS and Norwegian networks.

Near Mansfield, Nottinghamshire, five events with magnitudes ranging from 0.7 to 1.7 ML have been located, one of which was felt by local residents in the Mansfield Wosdhouse and Forest Town areas of Mansfield. At shallow depths of 1 km, they are believed to be of coal- mining origin.

Some 56 coalfield events with magnitudes ranging between 0.5 and 2.3 ML have been detected in 1995, thirteen of which were felt. Thirty-one of them located in the Clackmannan area in the central region of Scotland, where the magnitudes ranged from 0.5 to 1.8 ML; five of these were felt by local residents.

3 3. THE BGS UK SEISMOGRAPH NETWORK

3.1 Instrumentation

A standard seismic network consists of up to ten 'outstation' vertical seismometers radio-linked over distances of up to 100 km to a central site where the data, along with that from a local 3-component set of two horizontal and one vertical seismometers, are recorded onto a digital event-triggered recorder (SEISLOG). It is designed to trigger on events and write to a computer disk which is accessed from Edinburgh via a modem. Several times a day, automatic data transfers are made to the Edinburgh central computer and the events are analysed during that day providing a rapid response for location and magnitude determinations. Most of the recording centres in the UK have been upgraded to provide a SEISLOG system (Figs 1 and 2). At some centres, a continuous back-up facility is provided by the traditional magnetic tape Geostore recorders, and tapes are dispatched weekly, to Edinburgh for analysis. SEISLOGS have the advantage over the Geostore system of providing digital data, a wider dynamic range (72 db), a bandwidth of up to 40 Hz and the capacity for 32 seismic channels. The system also has the facility to auto-reboot in the event of mains power failure and this norrnally takes three minutes once power has recovered.

At some locations, on-line paper chart recorders display three channels to enable local operators to view earthquake data. At other stations, low-gain vertical seismometers extend the dynamic range of the system (by 34 db) to stronger motions, and low frequency microphones are used to aid the discrimination of sonic booms. In addition, strong motion accelerometers installed at several locations (near Hunterston, Torness, Cornwall, Chapelcross, Jersey, Hereford, Kyle, Swindon, NW Scotland, Kent and East Anglia) record accelerations up to 0.1 g. A broad-band station (Guralp) in Edinburgh records digitally, and provides an assessment of surface-wave (Richter magnitude) for large Global earthquakes.

Recent developments in geographic coverage of the UK are described in Walker and Browitt (1996, in press) and details of the SEISLOG system, which has been jointly developed by Bergen university and BGS are given in Utheim and Havskov (1993). In December 1995, 95% of the 138 UK stations were being recorded on a rapid access SEISLOG system.

3.2 Detection Threshold

The detection capabilities of a network depend upon station distribution, instrument sensitivity and background noise levels. For the BGS UK network, the lower limit of sensitivity is governed by the background noise level. The contours in Figure 2 illustrate the lower threshold 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 and livestock vary considerably with time (typically 0.5 to 15 nanometres, at 10 Hz) causing the magnitude thresholds to increase or decrease. In conditions of high noise, 0.8 ML should be added to the contour values.

The detection contours in Figure 2 hold true only if all stations are continuously monitored and this is not always the case. Small events in unmonitored areas may then go undetected unless they are felt and reported to BGS by local inhabitants. The detection capabilities by this process are strongly dependent on population density.

4 3.3 Envir o nm e nt a1 M o nit oring

The infrastructure provided by the UK nationwide seismic monitoring network, comprising remote sensing stations linked to computers, is ideal for expansion into a full-spectrum environmental monitoring network (including pollution, radioactivity and weather). An experimental station has been established some 35 km from Edinburgh where air and ground temperature, together with radioactivity measurements are being transmitted to a base station. There is the capacity to transmit data from up to 16 environmental sensors simultaneously. Hardware and software have been upgraded during the 12 month trial period to improve reliability and efficiency of data collection. Graphical display software has been developed for the PC and SEISLOG computers.

4. HYPOCENTRE PARAMETERS AND THEIR ERRORS

4.1 Epicentre Location

By accurately timing the signal onsets at a minimum of three stations, a location can be found for an earthquake which satisfies the observed pattern of arrivals. Instrumental locations in the bulletin were obtained using the computer program HYPO71 (Lee and Lahr, 1975) which iteratively adjusts a trial hypocentre (latitude, longitude, depth, and origin time) until the observed and computed arrival times coincide closely.

The accuracy of locations is dependent on distances from the closest stations, the distribution of the stations around the epicentre, the resolution to which signal onsets can be timed from the records, and the accuracy with which the seismic wave velocity through the earth can be modelled.

The velocity models used for the location of events in 1995 are given in Table 6 and were derived from a series of refraction profiles traversing Britain, LISPB (Bamford et al, 1976; Bamford et al, 1978; Assumpqao and Bamford, 1978 and Bott et al., 1985).

4.2 Depth Determination

The accurate determination of earthquake depth presents a more difficult problem, mainly because phase arrival patterns at the seismographs can still be satisfied for a large range of depths merely by adjusting the origin time to suit. Constraints on the depth can usually only be imposed when a station is very near the epicentre and even then the accuracy depends on the velocity model.

The best depth determinations have been obtained when an earthquake or earthquake series occurred almost beneath a network. For events at larger distances, and where the error columns (ERH and ERZ), in the tables, are blank, the depth errors can be up to tens of kilometres. The quality factor of the event, as listed in the tables (SQD), is an indication of the depth error. As a general guide only, A*A, A*B, B*A and possibly B*B class events, have reliable depths.

5 4.3 Seismicity Distribution

Owing to variability in the earthquake detection threshold, which is governed by ambient noise conditions and the geometry of the observing network (see 3.2), the bulletin is biased towards 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 1995, have been plotted in Figure 4. The data set is considered complete for these magnitudes in all localities of the onshore area. Seismicity for: the period 1970 to 1995 is shown in Figure 5 with a threshold magnitude of 3.5 ML. 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 a station near Kyle of Lochalsh (KYL). The dataset is likely to be complete for such magnitudes

4.4 Magnitude

All earthquakes in the bulletin have been assigned a local magnitude (ML) as defined by Richter (1 935): ML = log,, (A/Ao) where A is the maximum deflection (centre to peak in mm) registered by the earthquake on a Wood-Anderson seismograph and Ao is that for a 'standard' magnitude zero earthquake at the same distance. The rho term is thus a distance correction factor tabulated by Richter to 200, and later 600 km. Although Richter intended his method to be an approximate quantification of earthquake size and his attenuation term, Ao, strictly only applies to California, the forrnula is still used world-wide today. The ML magnitudes in this bulletin have been calculated according to Richter by converting the output of the BGS instruments to an equivalent Wood-Anderson deflection. Ideally, the measurements are made on two horizontal instruments and averaged but, if this was not possible, the mean of the magnitudes from a number of verticals has been used. Ground motion registered at a seismograph varies with 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. The resulting errors on magnitudes quoted in the bulletin will normally be less than 0.4 ML.

4.5 Intensity

Intensity is a measure of the effect of the shaking on people, structures and objects. It decreases with distance from a maximum value (10) usually found close to the epicentre. The maximum felt intensity is quoted, where known, on the European Macroseismic Scale (EMS),

(Grunthal, 1993). '.i

6 5. BULLETIN CONTENT AND COMPLETENESS

5.1 The Geographical Area

The bulletin covers all of the UK land mass and its coastal waters including the North Sea to 800 krnE and 1400 kd.

5.2 Events Included

All events believed to be due to true tectonic origins have been included, that is, events caused by natural stresses within the earth.

Coalfield events are also included. These are small events occurring near coal workings which are believed to be caused by the redistribution of stress as the coal is extracted and, in some cases by collapse in old workings. They are indicated by C/F in the comments column of Tables 1, 2 and 5.

Acoustic disturbances, such as sonic booms from supersonic aircraft, are included when they are felt. The air-borne waves are readily identified by their slow travel time across an array or by their signature on a microphone but they are frequently reported by local people as small earthquakes. They are indicated by 'SONIC' in both the locality and comments column of Tables 1 and 3. In 1995, 5 sonic events were reported felt and all were detected by the UK network.

Significant non-natural events which received media attention and felt explosions are also included in Tables 1 and 3. The felt explosions are indicated by 'EXPL' in both the locality and comments column. In 1995, one felt explosion was detected.

5.3 Events Excluded

Events 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, geophysical prospecting and civil engineering are all excluded where possible, unless reported to be felt. Unfortunately, identification by record character, location and time of occurrence is not always 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 Completeness

The contours of detection threshold in Figure 2 show that the whole of the UK is covered by the seismograph network for approximately magnitude 1.5 ML, and above, at times of average ambient noise levels. High noise levels may cause this threshold to rise to about 2.3 ML. Normally, however, an earthquake of this size would be felt, if not detected, in the areas of poorer instrumental coverage. The bulletin can, therefore, be assumed to be complete for all earthquakes of magnitude 2.3 and above.

Discussion

Near Avimore, Highlands, on 28 August 1995 an earthquake with a magnitude of 2.7 ML was felt by local residents in Boat of Garten, Aviemore, Grantown-on-Spey, Carrbridge and many other surrounding villages. Felt reports described "a bang, a rumble, the building shaking" and one person reported that ''ornaments moved and glasses shook"; a few reports of minor damage were also received. The earthquake was felt over 1300 km2'and located in an area where no previous seismicity had been recorded. A macroseismic survey throughout the region showed that it was felt in the epicentral area with a maximum intensity of 4 EMS. AVIEMORE, HIGHLAND 28 AUGUST 1995 09:59 UTC 2.7 ML

STOKE-ON-TRENT EARTHQUAKE, 20 FEBRUARY 1995

PARAMETERS

Date: 20 February 1995

Origin Time: 01:59 05.2 UTC

Latitude and longitude: 53.03' N 2.20' W

Grid Reference: 386.7 km E 348.8 km N

Depth: 3.8 km

Epicentral Error (1 std. dev.): 1.1 km

Depth Error (1 std. dev.): 2.8 km

Discussion

A swaim of earthquakes was located in the Stoke-on-Trent area in February. They had magnitudes ranging between 1.6 and 2.5 ML and six were felt by local residents. The largest (magnitude 2.5 ML) was felt throughout the Stoke-on-Trent area, with intensities of at least 4 EMS in the epicentral area. From the available data (nearest station some 25 km away), many of these events had characteristics typical of natural earthquakes but with some showing characteristics typical of mining-induced earthquakes. Similar swarms in the area were detected in the mid 1970's, early 1980's and early 1990's. STOKE-ON-TRENT 20 FEBRUARY 1995 01:59 UTC 2.5 ML

EUROPEAN MACRQSEISMIC SCALE (EMS 92)

APPENDIX C SYNOPSIS OF EMS-92 INTENSITY SCALE

1 - Not felt Not felt, even under the most favourable circumstances.

2 - Scarcely felt Vibration is felt only by individual people at rest in houses, especially on upper floors of buildings.

3 - Weak The vibration is weak and is felt indoors by a few people. People at rest feel a swaying or light trembling.

4 - Largely observed The earthquake is felt indoors by many people, outdoors by very few. A few people are awakened. The level of vibration is not frightening. Windows, doors and dishes rattle. Hanging objects swing.

5 - Strong The earthquake is felt indoors by most, outdoors by few. Many sleeping people awake. A few run outdoors. Buildings tremble throughout. Hanging objects swing considerably. China and glasses clatter together. The vibration is strong. Top heavy objects topple over. Doors and windows swing open or shut.

6 - Slightly damaging Felt by most indoors and by many outdoors. Many people in buildings are frightened and run outdoors. Small objects fall. Slight damage to many ordinary buildings eg; fine cracks in plaster and small pieces of plaster fall.

7 - Damaging Most people are frightened and run outdoors. Furniture is shifted and objects fall from shelves in large numbers. Many ordinary buildings suffer moderate damage: small cracks in walls; partial collapse of chimneys.

8 - Heavily damaging Furniture may be overturned. Many ordinary buildings suffer damage: chimneys fall; large cracks appear in walls and a few buildings may partially collapse.

9 - Destructive Monuments and columns fall or are twisted. Many ordinary buildings partially collapse and a few collapse completely.

10 - Very destructive Many ordinary buildings CO lapse.

11 - Devastating Most ordinary buildings col apse.

12 - Completely devastating Practically all structures above and below ground are heavily damaged or destroyed. ______,___****,___-,___- A complete description of the EMS-92 scale is given in: Grunthal, G., (Ed) 1993.
