- Abstract
- Earthquakes is a point theme repersenting earthquakes worldwide. Attribute information includes the magnitude, depth date and intensity of the earthquakes.
- Purpose
- For educational, non-commercial purposes. This dataset is appropriate for use in a GIS.
- Supplemental Information
- Earthquakes are caused by the release of energy in relatively small areas of the earth's crust or upper mantle. Powerful earthquakes are much more rare than weak ones. For example, earthquakes of magnitude 7.0 occur only one-tenth as often as the number of earthquakes of magnitude 6.0. Two different measurements are commonly used to describe the power of earthquakes: magnitude and intensity. Magnitude is measured on the Richter scale. It is calculated from the amplitude (side-to-side movement) of seismic waves measured at multiple locations, ideally about 100 kilometers away from an earthquake's focus. Seismographs are used to record the information about wave amplitude. The Richter scale is a logarithmic scale where each number has ten times the wave amplitude (and about 31.5 times the total energy release) of the previuos number. The magnitude of the most powerful recorded earthquakes is 8.7. Intensity measures the effects of an earthquake, especially the effects on people and structures. It is measured by observations of people witnessing the earthquake aswell as an assessment of damages afterward. Intensity is measured on the Mercalli scale, which ranges from 1 to 12. Intensity is influenced by such things as the strength of the earthquake, distance from the epicenter, the kind and density of structures in the local area, local geology, and the time of day. Intensity is valuable for estimating the strength of historical earthquakes which are known by written accounts and other evidence from long ago. However, intensity is not useful for describing earthquakes in uninhabited areas, such as beneath the ocean.
