Global plot of significant earthquakes
The Significant Earthquake Database is a global listing of over 5,700 earthquakes
from 2150 BC to the present. A significant earthquake is classified as one that meets
at least one of the following criteria: caused deaths, caused moderate damage (approximately
$1 million or more), magnitude 7.5 or greater, Modified Mercalli Intensity (MMI) X
or greater, or the earthquake generated a tsunami. The database provides information
on the date and time of occurrence, latitude and longitude, focal depth, magnitude,
maximum MMI intensity, and socio-economic data such as the total number of casualties,
injuries, houses destroyed, and houses damaged, and $ dollage damage estimates. References,
political geography, and additional comments are also provided for each earthquake.
If the earthquake was associated with a tsunami or volcanic eruption, it is flagged
and linked to the related tsunami event or significant volcanic eruption.

| Lineage Statement | The Significant Earthquake database originated from the Significant Earthquake Catalog (Ganse, Robert A., John B. Nelson, 1981). The aforementioned catalog was an expansion of a file originally created to produce the World Map of Significant Earthquakes 1900 to Present (1979). The database is now updated regularly from sources such as U.S. Geological Survey, national and government databases and reports, earthquake and tsunami catalogs, post-event reconnaissance reports, journal articles, newspapers, internet pages, email and other written documents. |
