Wheeler Publication_Date: 2001 Title: Digital spatial data for the map "Earthquakes in and near the northeastern United States, 1638-1998" Geospatial_Data_Presentation_Form: map Series_Information: Series_Name: U.S. Geological Survey Geologic Investigations Series Issue_Identification: I-2737 Online_Linkage: http://pubs.usgs.gov/imap/i-2737/ Description: Abstract: The data are those used to make a large-format, colored map of earthquakes in the northeastern United States and adjacent parts of Canada and the Atlantic Ocean (Wheeler, 2000; Wheeler and others, 2001; references in Data_Quality_Information, Lineage). The map shows the locations of 1,069 known earthquakes of magnitude 3.0 or larger, and is designed for a non-technical audience. Colored circles represent earthquake locations, colored and sized by magnitude. Short descriptions, colonial-era woodcuts, newspaper headlines, and photographs summarize the dates, times of day, damage, and other effects of notable earthquakes. The base map shows color-coded elevation, shaded to emphasize relief. Purpose: The map is an educational tool with which to inform the public about the existence and the broad, regional nature of earthquake hazard in the Northeast. The data were created digitally in order to ease and speed production and publication of the map. Text on the map cautions against using the map for scientific or engineering purposes, or to estimate hazard in small areas or at single sites. Entries in Lineage under Data_Quality_Information explain the reasons for this caution (see also Wheeler, 2000; reference in Lineage). The earthquake catalog was constructed in such a way that it should not be utilized in scientific, engineering, or hazards use ( Wheeler, 2000; reference in Lineage). Accordingly, the catalog is not being published separately, in order to minimize the potential for misuse. It is available only as part of the digital files from which the entire map was made. Supplemental_Information: This metadata record describes the data on earthquakes and topography. Other data, such as for roads and urban areas, were obtained elsewhere and we lack metadata for them. Instead, this field cites the sources of these data that were obtained elsewhere.

Native_Data_Set_Environment: SunOS, 5.6, sun4u UNIX, ARC/INFO version 7.2.1 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: No formal tests were devised for attribute accuracy of the earthquake epicentral parameters and magnitudes (other than checking transfer of values to the input data file) because attribute accuracy was best ascertained by individual contributors to the master catalog. See also Horizontal_Positional_Accuracy_Report. Logical_Consistency_Report: Logical consistency checks were conducted during preparation of the map by visual examination of the positions of plotted symbols on the base map (searching for spurious locations) and cross-checking the tabular locations and magnitudes of the largest earthquakes against their graphical representation. Completeness_Report: Small or old earthquakes are more likely to have been missed than large or recent ones. Because limited resources required use of existing earthquake catalogs, the catalog compiled for the map may contain duplicates, omissions, and blasts or other nonseismic events. Text on the map explains these factors at greater length. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Accuracies of the earthquake locations vary with earthquake magnitude, date of occurrence, closeness to settled areas, and method used to calculate or estimate the location. Locations of modern earthquakes may be reported to the nearest 0.0001 degree and may be accurate to within several kilometers. Locations of earthquakes that predate the installation of seismographs may be known only to the nearest tenth or half a degree, or even to the nearest whole degree. All locations were taken from standard sources, and none were tested or modified. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No depth information was included in the source table.

Wheeler Publication_Date: 2000 Title: Earthquakes of the northeastern United States and adjacent Canada, 1638-1998--Construction of the earthquake catalog for an outreach map Geospatial_Data_Presentation_Form: text Series_Information: Series_Name: U.S. Geological Survey Open-File Report Issue_Identification: 00-0316, 6 p. Publication_Information: Publication_Place: Denver, Colorado Publisher: U.S. Geological Survey Other_Citation_Details: No existing earthquake catalog provided current, roughly uniform coverage of the map area. Instead, parts of the area are covered by two regional seismograph networks and the Canadian national network, and several states maintain or are compiling their own lists of earthquakes from various sources. Accordingly, making the map required compilation of a catalog. Because this map is designed for the public and not for scientific or engineering use, the map should show each state's earthquakes in a manner consistent with the way that state's authoritative persons or organizations show them. This principle of consistency with authoritative sources in each state was urged by one state geologist within the map area, and it was welcomed by members of other state geological surveys who were contacted during catalog construction. Accordingly, there are two main differences between this catalog and one that would result from a seismologist's research. First, I have not examined the original seismographic or intensity data. Second, the combination of sources used and the relative preference given to each source changed from State to State, and from Canada to the United States. Therefore, the map and its catalog should NOT be used for scientific or engineering purposes, nor to assess seismic hazards or losses. However, the map still shows the relative differences of seismicity between States and large parts of States. The larger damaging earthquakes have been vetted individually by local seismologists.
