地震监测和信息服务的目标是开发和维护英国全国地震活动数据库，用于地震危险性评估，并对重大事件的发生或报告的发生提供近乎即时的反应。英国地质调查局(BGS)的任务是运营和进一步发展全英国统一的地震仪台网，以便长期获取标准化数据。该项目得到了由副总理办公室(ODPM)担任主席的一组组织的支持，自然环境研究理事会(NERC)提供了大量财政投入。
在该项目的第15年，建立了四个新的宽带地震台站，其中三个站点部署了强震加速度计。另外四个站升级为高动态范围数据采集。除一个地震子网络外，所有地震子网络现在都使用在QNX操作系统下运行的数据记录器。购买了10台便携式数据记录仪，可以快速部署，以记录余震序列和震群的数据，并研究特定地区。
所有重大的感觉到的事件和其他一些事件都通过电子邮件发送的地震警报迅速报告给客户小组。这些警报也发布在互联网上(http://www.earthquakes.bgs.ac.uk).每月发布了六周的地震公报，经修订后编成了年度公报(Simpson，2004年)。在所有报告地区，已实现或超过预定目标。
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 British Geological Survey (BGS) has been charged with the task of operating and further developing a uniform network of seismograph stations throughout the UK in order to acquire standardised data on a long-term basis. The project is supported by a group of organisations under the chairmanship of the Office of the Deputy Prime Minister (ODPM) with major financial input from the Natural Environment Research Council (NERC).
In the 15th year of the project four new broadband seismograph stations were established, with strong-motion accelerometers deployed at three of these sites. A further four stations were upgraded to high dynamic range data acquisition. All except one of the seismic sub-networks now use data loggers running under the QNX operating system. Ten portable data loggers were purchased, which can be rapidly deployed to record data from aftershock sequences and earthquake swarms and to study specific areas.
All significant felt events and some others 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, following revision, were compiled into an annual bulletin (Simpson, 2004). In all reporting areas, scheduled targets have been met or surpassed.
