Advanced National Seismic System (ANSS) ComCat earthquakes<\/i><\/span><\/p>

This layer contains earthquake events from the ANSS ComCat earthquake catalog (https://earthquake.usgs.gov/earthquakes/search/) and includes earthquake hypocenters, magnitudes, and other seismic information. The database contains all natural seismic events within the bounding coordinates of 45.5°N, 111.5°W and 40.5°N, 103.5°W dating back to 1959. Additional data regarding seismic events related to mine explosions/collapses and other anthropogenic-sourced events can be found via ComCat. Data are \u201cas is\u201d and have not been reviewed or corrected by the WSGS. Data resolution can be found in the attribute table. Updates are completed monthly. Metadata and documentation for this layer can be found at <\/span>https://earthquake.usgs.gov/data/comcat/<\/span><\/a>. The layer containing the "last month" earthquakes consists of the last full month of records, the "all" layer includes these and historic records.<\/span><\/p>

100 Years of Earthquakes in the Wyoming Region (1871\u2013<\/span>1970)<\/i><\/p>

This layer is a summary of select earthquakes in and near Wyoming that occurred between 1871 and 1970. It is modified from the original database, created by James C. Case and others. The information was gathered from numerous sources, however, much of the data were sourced from the National Earthquake Information Center. The dataset includes earthquakes with magnitudes greater than 2.5 or those that created ground<\/span>\u2013<\/span>shaking intensities of II or greater based on the Modified Mercalli Intensity Scale. Many of the events in this database occurred prior to adequate instrumentation and were compiled from anecdotal evidence via newspapers and reports. For this reason, those records may or may not have related magnitudes. In those cases, intensities were determined based on historic record. Although great care was taken assembling the dataset, it is not considered to be complete. Data points were calculated at multiple scales and should not be considered to be exact.
