  • Scanned images of seismic phase data sheets containing phase readings, phase arrival times, amplitude data, magnitude data and derived source information like hypocentres (locations), fault plane solutions etc for earthquakes recorded by BGS seismic stations. The data is in the format used by the location program HYPO71 (Lee & Lahr, 1975) which was the most used program for local earthquakes.

  • The data is from four three-component broadband seismometers deployed along the lower east rift zone during the 2018 Kilauea eruption for four months. The instruments were deployed towards the end of July before the eruption ceased, and were placed in locations that would complement the existing USGS seismic network.

  • This is continuous raw data from 3-component broad-band (30 sec to 100 Hz) Guralp 6TD seismometer deployments around Askja in the central region of Iceland.

  • The UK Onshore Geophysical Library was established in 1994 in conjunction with the Department of Trade and Industry (DTI) and the UK Onshore Operators Group (UKOOG). The Library manages the archive and official release of seismic data recorded over landward areas of the UK. By agreement with the DTI and HMSO, the Library operates as a registered charity, funded by revenues raised from data sales and donations, with the long term objective of bringing all available UK onshore digital seismic data into secure archival storage, whilst providing efficient access to all interested parties. BGS has access to the data at cost of copying only for science budget work. Data index on the BGS Geoscience Data Index.

  • Data collected as part of a UK/French/US collaborative effort to record aftershocks from the 2016 Pedernales Earthquake in Ecuador. The dataset comprises continuous seismic data recorded on broadband and short period instrumentation.

  • This dataset contains broadband seismic data collected between May 2018 and January 2019 as part of the Unsettled Earth project funded by the University of Bristol's Brigstow Institute. The seismic station was deployed in one of the turrets of the Wills Memorial Building Tower, Bristol.

  • This dataset contains data from two seismic and one infrasound array deployed at Mt. Etna during the late part of the 2020-2021 eruptive crises (May-November 2021). The arrays were composed as follow: 1) a 7-element array of 3-component, broadband (Trillium T120 compact) seismometers; 2) a 5-element array of 3-component short-period (Lennartz LE-3Dlite-MkII); 3) a 6-element array of broadband infrasound microphones (IST2018). All data were recorded with a sampling rate of 100 Hz and 24-bit resolution using Digos Datacube3 digitizers. The data were collected through a collaboration between the University of Liverpool, UK, and the Istituto Nazionale di Geofisica e Vulcanologia (INGV), Italy, with the purpose of characterizing pre- and syn-eruption tremor signals at Etna, and their links to the timing, style and intensity of paroxysmal eruptive activity at the volcano. The dataset contains records of different examples of paroxysmal activity (i.e., intense episodes of sustained Strombolian explosions accompanied by emission of ash at the vent) as well signals associated with as explosive degassing at the summit vent. Data recovery rates for this experiment were high; there are only very minor gaps in the data owing to periods of scheduled maintenance and data download during the deployment period.

  • The map shows the location and line-identifiers of reflection seismic profiles acquired by the former National Coal Board and British Coal during their exploration for coal in the UK. Ownership of UK coal exploration data was transferred to the Coal Authority following privatisation of the UK coal industry. The Coal Authority have appointed the British Geological Survey as custodian of this important national geological data archive. These data are, in general, publicly available; however, access to data within active mining licences is restricted in that it requires the consent of the mining licensee. The Coal Authority data archive includes hardcopy and digital data for the reflection seismic profiles, such as film and paper prints, original field tapes, demultiplexed data, processed stacked data, navigation (location) data and observers' and surveyors' acquisition reports. But please note that not all data types are available for all profiles. The BGS will be pleased to provide information on data availability for named profiles or within specified geographic areas, together with cost estimates and options for supplying copies.

  • A seismic dataset of 70 temporary and 3 permanent seismic stations deployed from 05/2012 to 10/2013 in northern Turkey. Three-component seismic data were collected at each location. Stations were deployed across the North Anatolian Fracture Zone (NAFZ) in the region of the 1999 Izmit and Duzce earthquakes. The network covered a footprint of ~35 by 70 km with a nominal station spacing of 7 km. Continuous seismic data were collected to study the crustal structure of the NAFZ to better understand the structure and dynamics of the NAFZ and it seismic hazard for the region. Funding for the project was provided through NERC Standard grant NE/I028017/1 and 63 stations were provided by the GEF. Additional stations were provided by the Kandilli Observatory and Earthquake Research Institute. Seismic stations were a mixture of Guralp CMG-6TD and CMG-3T.
