Reconnaissance geologic map of the Loreto and part of the San Janier quadrangles, Baja California Sur, Mexico Reconnaissance geologic map of the Loreto and part of the San Janier quadrangles, Baja California Sur, Mexico

The Loreto area of Baja California Sur, Mexico, contains a diverse association of igneous, sedimentary, and metasedimentary rocks exposed in the foothills and arroyos between the Sierra La Giganta and Gulf of California. The Loreto area was selected for this study to examine the possible relation of the marine rocks to the opening of the Gulf of California, and to determine the...

Seismicity map of the state of Colorado Seismicity map of the state of Colorado

This map is one of a series of seismicity maps produced by the U.S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of Colorado, even though earthquakes in nearby states may have been felt or may have caused damage in Colorado. The data in...
