Seismic-reflection profiles of the New Madrid seismic zone-data along the Mississippi River near Caruthersville, Missouri Seismic-reflection profiles of the New Madrid seismic zone-data along the Mississippi River near Caruthersville, Missouri

The tectonic setting and the earthquake hazards of the New Madrid seismic zone in the northern Mississippi embayment have been the subject of intensive study the past several years as part of the Earthquake Hazard Reduction Program of the USGS (U.S. Geological Survey). These efforts have improved our knowledge of the geologic history, general tectonic setting, and patterns of modern...

Seismicity map of the state of Arizona Seismicity map of the state of Arizona

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 Arizona, even though earthquakes in nearby states or countries may have been felt or may have caused damage in Arizona...

Seismicity map of the state of Idaho Seismicity map of the state of Idaho

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 Idaho, even though earthquakes in nearby states or countries may have been felt or may have caused damage in Idaho. The...

Seismicity map of the state of Utah Seismicity map of the state of Utah

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 Utah, even though earthquakes in nearby states or countries may have been felt or may have caused damage in Utah.

Stratigraphic framework of coal beds underlying the northeastern part of the Fort Peck Indian Reservation, Montana Stratigraphic framework of coal beds underlying the northeastern part of the Fort Peck Indian Reservation, Montana

The area of investigation is located in the northeast part of the Fort Peck Indian Reservation (fig. 1) on the western flank of the Williston Basin. It covers about 450 square miles and is made up of parts of Daniels, Sheridan, and Roosevelt counties. Exploratory drilling for coal and logging of seismograph drill holes in 1978-1981 were done with the support of the Branch of Indian...

Structure contour map of the tops of the Kreyenhagen Formation and Cretaceous strata in the Coalinga area, Fresno and Kings counties, California Structure contour map of the tops of the Kreyenhagen Formation and Cretaceous strata in the Coalinga area, Fresno and Kings counties, California

This structure contour map, originally compiled during a study of the 1983 Coalinga earthquakes, shows the general structural configuration of the upper several kilometers of section in the Coalinga area. It was compiled by using electric well-log data available through April 1982 (Ammann Map Services, 1978; Petroleum Information Corporation, 1982; California Division of Oil and Gas...
