| Map showing the Earth's physiographic features, the current movements of its major tectonic plates, and the locations of its volcanoes, earthquakes, and impact craters. The use of colour and shaded relief helps identify significant features of the land surface and the ocean floor. Over 1,500 volcanoes active during the past 10,000 years are plotted on the map in four age categories. The locations (epicentres) of over 24,000 earthquakes, largely from 1960 through 1990, are plotted in three magnitude categories and in two depth ranges. The document is in PDF format and requires Acrobat Reader 3.0 to view and print.

Extensive list of Internet resources where original seismic data or seismic research information is available.

Consortium of US universities with research programs in seismology, established to acquire and distribute seismic data. Features a data management system which coordinates data inflow from seismic recording stations, a seismic monitor link for a quick view of current seismic activity, a SeismiQuery database allowing users to search for data by day, month, station or event, a help facility for new users, and a collection of graphics and information on recent earthquakes.

An interface that uses data available from the National Earthquake Information Center, part of the US Geological Survey. This data provides basic information about earthquakes within hours of them taking place. In response to a query, the data is dynamically accessed from a USGS server in Golden, Colorado. The data is then processed into an appropriate format in Edinburgh and displayed using the Xerox PARC Map Viewer based in Palo Alto, California.

Summary of the Richter Scale for measuring earthquakes, invented by Charles Richter in 1935. The Richter Scale uses a seismograph to measure seismic waves.

Details of date, time, location, depth and magnitude of recent seismic alerts in the UK and worldwide.

The Southern California Integrated GPS Network (SCIGN) is a collaborative project to install 250 permanent, continuously recording Global Positioning System (GPS) receivers in and around the Los Angeles basin to provide accurate deformation information that will improve estimates of earthquake hazards. With this satellite technology, scientists are able to obtain extremely precise measurements of motions of the surface of the earth and the motion of the tectonic plates that make up its crust.

A worldwide earthquake catalog created by merging the master earthquake catalogs from contributing CNSS member institutions.

Latitude, longitude, date and time of earthquakes in Canada and the United States in recent weeks.

An interactive program designed to introduce the concepts of how an earthquake epicentre is located and how the Richter magnitude of an earthquake is determined. It shows the recordings of an earthquake's seismic waves detected by instruments far away from the earthquake. Students are shown how to locate the epicentre by making simple measurments on three seismograms and to determine the Richter magnitude of the earthquake.
