Overview of the research group Geophysical Unit of Menlo Park (GUMP) with links to studies, models, and maps on gravity and geomagnetism in Nevada, California, Oregon, Washington and the U.S.
Lists of largest earthquakes in the world and in the United States, earthquake facts and statistics, deaths from earthquakes, earthquakes by magnitude, and significant earthquakes.
National seismic hazards maps, global seismic hazards map, predictive intensity maps, shaking hazards maps and probabilities for California, and a variety of fact sheets on earthquakes.
Provides detailed technical information on earthquake hazards in the form of frequently asked questions. Designed for the technical audience, including building and safety planners.
Near-real-time maps of location, ground motion, and shaking intensity of earthquakes in California and Nevada for the past hour, past day, and past week and links to other earthquake information.
Aeromagnetic surveys of New England, merged to form seamless grids across the state. Gravity anomaly data are provided as well. Data provided in a variety of formats.
A method to create qualitative images of thick oil in oil spills on water using near-infrared imaging spectroscopy data. It relies on the organic absorption features of chemical bonds in aliphatic hydrocarbons. The data cannot give oil volume estimates.
