|Global Significant Earthquake Database, 2150 BC to present
||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.
