British Geological Survey
The British Geological Society has a website dedicated to the study of earthquakes. The website provides information about earthquakes in the UK and abroad. The seismic hazard in the UK is illustrated on a map, which was produced in connection with the introduction of Eurocode 8 (the current pan-european standard for earthquake-resistant design of structures). The map shows the levels of peak ground acceleration that may be expected in different parts of the country with an average return period of 2,500 years.
Center for Engineering Strong Motion Data
The Center for Engineering Strong Motion Data (CESMD) collects records of ground motions and structural responses that occur during earthquakes. The Center is a cooperative effort between the California Geological Survey and the US Geological Survey. The target user group includes reseachers and specialist earthquake engineers. The CESMD website allows users to view and download records from recent or archived historical earthquakes. It is also possible to search for records based on various parameters such as magnitude or hypocentral distance. The majority of the records held by the Center originate from the US West Coast, but with cooperation from colleagues at other seismic networks, CESMD also provides strong-motion data from significant earthquakes that occurred in countries such as Italy, Haiti, Mexico, New Zealand, Chile, Japan and Turkey.
The European Facilities for Earthquake Hazard & Risk
The EFEHR web platform provides access to data, models, tools and expertise relevant for assessment of seismic hazard and risk in Europe. This is a specialist tool, which requires some expertise to use and interpret. The EFEHR platform is hosted at ETH Zurich and operated by the Swiss Seismological Service (Schweizerischer Erdbebendienst SED), in close collaboration with EUCENTRE Pavia. It was sponsored by the EU FP7 project NERA from 2010 to 2014. In particular, the EFEHR platform can be used to generate seismic hazard maps and hazard curves for any location in Europe.
The GMPE Compendium
The GMPE compendium is maintained by John Douglas, a Chancellor's Fellow (Lecturer) at the University of Strathclyde, Glasgow, UK. From the website:
Ground motion prediction equations (GMPEs) are mathematical expressions to estimate the earthquake shaking that would be felt at a site given the occurrence of an earthquake of a certain size at a nearby location. GMPEs play a key role in engineering seismology and earthquake engineering as they are used to provide estimates of the forces that a structure may undergo during an earthquake. GMPEs generally provide a prediction in terms of an scalar intensity measure (IM) of the earthquake shaking. The compendium provided by this website provides details of published models for the commonly-used IMs.
The US Geological Survey (USGS) publishes a wide variety of data related to earthquakes, both recent and historical. This includes the ShakeMaps, which shows various intensity measures superimposed on regional maps. The USGS also provides maps and other tools for the purpose of engineering design (in accordance with ASCE 7 – an American standard that specifies design loads for buildings and other structures). The Earthquake Topics for Education contains multiple resources for students of all ages – ranging from primary school children all the way up to university graduates.
