Count Component Title Abstract
1 NCEI/WDS 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.

      1 Latitude Distance measured north or south from the equator. Distance north is positive, distance south is negative.
      1 Longitude Longitude is measured from the Prime Meridian (which is the north/south line that runs through Greenwich, England), values measured east are positive and values measured west are negative.
      1 Focal Depth The depth of the earthquake is given in kilometers, positive downward.
      1 State The state in the country in which the volcano is located.
      1 Country The country in which the volcano is located.
      1 Region The global region in which the volcano is located.
      1 Magnitude The value in this column contains the primary earthquake magnitude. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. For pre-instrumental events, the magnitudes are derived from intensities. There are several different scales for measuring earthquake magnitudes. The primary magnitude is chosen from the available magnitude scales in this order: Mw Magnitude, Ms Magnitude, Mb Magnitude, Ml Magnitude, Mfa Magnitude, Unknown Magnitude
      1 Associated Hazard Whether or not the earthquake caused a tsunami and/or occurred in conjunction with a volcanic eruption.
      1 Number of Deaths from the Earthquake Whenever possible, numbers of deaths are listed. When references give different death tolls, each death toll and corresponding reference is listed as a separate record.
      1 Number of Injuries from the Earthquake Whenever possible, numbers of injuries from the earthquake are listed.
      1 Damage in Millions of Dollars from the Earthquake The value in the Damage column should be multipled by 1,000,000 to obtain the actual dollar amount. When a dollar amount for damage was found in the literature, it was listed in the Damage column in millions of U.S. dollars. The dollar value listed is the value at the time of the event. To convert the damage to current dollar values, please use the Consumer Price Index Calculator. Monetary conversion tables for the time of the event were used to convert foreign currency to U.S. dollars.
      1 Number of Houses Destroyed by the Earthquake Whenever possible, numbers of houses destroyed are listed.
      1 Number of Houses Damaged by the Earthquake Whenever possible, numbers of houses damaged are listed.

      Count Component Name Definition
      1 Modified Mercalli Intensity (MMI) The Modified Mercalli Intensity (Int) is given in Roman Numerals (converted to numbers in the digital database).
      1 Description of Number of Deaths from the Earthquake When a description was found in the historical literature instead of an actual number of deaths, this value was coded and listed in the Deaths De column. If the actual number of deaths was listed, a descriptor was also added for search purposes.
      1 Description of Number of Injuries from the Earthquake When a description was found in the historical literature instead of an actual number of injuries, this value was coded and listed in the Injuries De column. If the actual number of injuries was listed, a descriptor was also added for search purposes.
      1 Description of Damage from the Earthquake For those events not offering a monetary evaluation of damage, the following five-level scale was used to classify damage (1990 dollars) and was listed in the Damage De column. If the actual dollar amount of damage was listed, a descriptor was also added for search purposes. When possible, a rough estimate was made of the dollar amount of damage based upon the description provided, in order to choose the damage category. In many cases, only a single descriptive term was available. These terms were converted to the damage categories based upon the authors apparent use of the term elsewhere. In the absence of other information, LIMITED is considered synonymous with slight, minor, and light, SEVERE as synonymous with major, extensive, and heavy, and EXTREME as synonymous with catastrophic. Note: The descriptive terms relate approximately to current dollar values.
      1 Description of Number of Houses Destroyed by the Earthquake For those events not offering an exact number of houses destroyed, the following four-level scale was used to classify the destruction and was listed in the Houses Destroyed De column. If the actual number of houses destroyed was listed, a descriptor was also added for search purposes.
      1 Description of Number of Houses Damaged by the Earthquake For those events not offering an exact number of houses damaged, the following four-level scale was used to classify the damage and was listed in the Houses Damaged De column. If the actual number of houses destroyed was listed, a descriptor was also added for search purposes.
