World (Earthquakes, 2003)
- This data base provides information on earthquakes from2100 B.C. to the present. The data base containsearthquakes with known magnitude values between 0.1 and9.9. Earthquakes that have no computed magnitude values arealso included in the data base. Users of micro-earthquakedata (magnitude less than or equal to 0.0) should contactinstitutions that operate seismograph networks in theirarea of interest. In reality, there are very few eventswith magnitude less than 2.0 in the data base.
