| Abstract |
The British Geological Survey (BGS) operates a network of seismometers throughout the UK in order to acquire seismic data on a long-term basis. The aims of the Seismic Monitoring and Information Service are to develop and maintain a national database of seismic activity in the UK for use in seismic hazard assessment, and to provide near-immediate responses to the occurrence, or reported occurrence, of significant events. The project is supported by a group of organisations under the chairmanship of the Office for Nuclear Regulation (ONR) with major financial input from the Natural Environment Research Council (NERC).
In the 24th year of the project, two new broadband seismograph stations were established, giving a total of 40 broadband stations. Real-time data from all broadband stations and nearly all other short period stations are transferred directly to Edinburgh for near real-time detection and location of seismic events as well as archival and storage of continuous data. Data latency is generally low, less than one minute most of the time, and there is a high level of completeness within our archive of continuous data.
All significant events were reported rapidly to the Customer Group through seismic alerts sent by e-mail. The alerts were also published on the Internet (http://www.earthquakes.bgs.ac.uk). Monthly seismic bulletins were issued six weeks in arrears and compiled in a finalised annual bulletin (Galloway, 2013).
Four papers have been published in external journals. A chapter was also published in the New Manual of Seismological Observatory Practice. Three presentations were made at international conferences. Four BGS internal reports were prepared. We have continued to collaborate widely with academic partners across the UK and overseas on a number of research initiatives. |
