- Abstract
- U.S. National Atlas Historic Earthquakes represents the locations of significant, historic earthquakes in United States and adjacent Canada and Mexico that caused deaths, property damage, and geological effects, or were otherwise experienced by the resident populations.
- Purpose
- U.S. National Atlas Historic Earthquakes provides the locations of significant, historic earthquakes for geographic display and analysis at regional and national levels. This data set is intended for a mixed audience of specialists and non-specialists alike who have a need for general, non-technical information about significant U.S. earthquakes.

- Data Quality Information
- Attribute Accuracy Report
- The attribute table was scanned for unreasonable attribute values of depth and magnitude.
- Logical Consistency Report
- No formal tests for logical consistency were performed on this data set, principally because the data set contains attribute values that were arrived at by either or both quantitative (i.e. instrumental) and qualitative (i.e. historical) methods. Earthquakes that occurred prior to the introduction of seismological instrumentation are known only from written records, such as newspapers, books and journals, and diaries, which often may provide contradictory information that has to be carefully examined and weighed. As seismographs became more common in the early 1960's, the origin time and location were both more precisely and accurately determined but the compilation and evaluation of intensity reports was, and still is, a process that involves considerable subjectivity. As a result, all attributes associated with a given earthquake should be considered provisional and subject to further revision based on acquisition of new information and use of new analytical methods. The shapefile is converted to SDC (Smart Data Compression) format using either ESRI SDC Data Development Kit Professional 2 (DDKP2) or tools in ArcGIS. The SDC data set is then loaded into ArcSDE® to verify and validate the geometry.
- Completeness Report
- This data set contains information on significant, historical earthquakes that caused deaths, property damage, geological effects, or that were experienced by populations in the epicentral area, for the United States, Puerto Rico, and the U.S. Virgin Islands, and adjacent Canada and Mexico. These data are limited to the best estimates of earthquake locations and to attributes such as magnitude and maximum intensity. After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
- Horizontal Positional Accuracy Report
- 100 meters is the nominal precision of the reported instrumentally located coordinate values but accuracy is considerably less. Accuracy depends upon numerous factors including imprecision of the velocity model of the earth, uneven distribution of seismic stations, and imprecisions in the computational algorithm. Following initial proofreading of the input data file, a preliminary map of the locations of the earthquakes was produced which was examined for gross errors in spatial location.

- Felt by nearly everyone; many awakened. Some dishes, windows broken. Unstable objects overturned. Pendulum clocks may stop.
- 6
- Felt by all; many frightened. Some heavy furniture moved; a few instances of fallen plaster. Damage slight.
- 7
- Damage negligible in building of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built or badly designed structures; some chimneys broken. Noticed by persons driving motorcars.
- 8
- Damage slight in specially designed structures; considerable in ordinary substantial buildings with partial collapse. Damage great in poorly built structures. Fall of chimneys, factory stacks, columns, monuments, and walls. Heavy furniture overturned.
- 9
- Damage considerable in specially designed structures; well-designed frame structures thrown out of plumb. Damage great in substantial buildings, with partial collapse. Buildings shifted off foundations.
