Provides online access to extensive datasets covering the intersection of the social, natural, and information sciences, and specializes in on-line data and information management, spatial data integration and training, and interdisciplinary research related to human interactions in the environment.
This web site is sponsored by the USGS Earthquake Hazards Program, as part of our effort to provide and apply relevant earthquake science information and knowledge to reduce deaths, injuries, and property damage from earthquakes.
Determines, as rapidly and as accurately as possible, the location and size of all significant earthquakes that occur worldwide. Collects and provides to scientists and to the public an extensive seismic database that serves as a solid foundation for scientific research, principally through the operation of modern digital national and global seismograph networks and through cooperative international agreements. Pursues an active research program to improve its ability to locate earthquakes and to understand the earthquake mechanism.
Originally established in 1987 to provide the USGS with accurate and cloud-free photographs for creating and revising USA topographic maps. These images now serve as an archive that documents historic land surface and vegetation conditions.
Mission is to enhance public safety and minimize social and economic disruption from eruptions through delivery of effective forecasts, warnings, and information of volcano hazards based on scientific understanding of volcanic processes.
The National Geologic Map Database contains digital copies of recent and historic geologic maps of the United States and its territories. Features include an advanced search, an index of geologic terms, information about current geologic mapping projects, and MapView, a map-based visual browsing interface.
A catalog of USGS Publications (current and historic maps, aerial photos, satellite images, datasets, reports) and other products (screensavers, earth science image sets for teaching) available for purchase or for free download.
Searchable lists of titles for bulletins,professional papers, circulars, water-supply papers, and thematic maps back to 1948.
Ring of Fire - Full Documentary
The Ring of Fire is a long chain of volcanoes and other tectonically active structures that surround the Pacific Ocean. More than 450 active and dormant volcanoes are located here. Published May 28, 2014 by Natural World
An international organization devoted to the study of clays and clay minerals. We encourage exchange of research findings through the publication of Clays and Clay Minerals, sponsorship of an annual meeting, online access to the archived journals, special publications, the Source Clays Repository, and other network building activities.
Encourages fundamental research about natural materials; supports the teaching of mineralogical concepts and procedures; and attempts to raise the scientific literacy of society with respect to issues involving mineralogy in the widest sense.
