The DART system consists of a bottom pressure recorder (BPR) located on the sea floor capable of detecting a tsunami as small as 1 centimeter high on the ocean surface. A discus-shaped buoy, 2.5 meters in diameter, on the ocean surface is moored at a position close enough to receive data via acoustic link from the BPR. After receiving data from the BPR, the surface buoy relays the information via the NOAA Geostationary Operational Environmental Satellite (GOES) system to ground stations. The ground stations demodulate the signals and disseminate information to NOAA Tsunami Warning Centers (TWC) and the Pacific Marine Environmental Laboratory. TWCs use the data in real time to decide what U.S. coastal communities...

The Geospatial Multi-Agency Coordination Group, or GeoMAC, is an internet-based mapping tool originally designed for fire managers to access online maps of current fire locations and perimeters in the conterminous 48 states and Alaska. Perimeters are submitted to GeoMAC by field offices and then posted to an FTP site for downloading. This file contains fire perimeters submitted from the year 2001 to 2009. The projection is geographic and the datum is NAD83. Last updated in November, 2010.

This map layer contains the locations and attributes of significant, historic earthquakes that caused deaths, property damage, and geological effects, or were otherwise experienced by populations in the United States, Puerto Rico, and U.S. Virgin Islands. Included are earthquakes located in the United States as well as some that occurred in adjacent portions of Canada and Mexico. The main sources for the data are Seismicity of the United States, 1568-1989 and the Preliminary Determination of Epicenters for 1990 to August 2009. This is a replacement for the January 2005 map layer.

This database provides information on tsunami source events and locations where effects from tsunamis were observed. It includes events from 2000 B.C. to the present in the the Atlantic, Indian, and Pacific Oceans; and the Mediterranean and Caribbean Seas.

This map layer includes Holocene volcanoes, which are those thought to be active in the last 10,000 years, that are within an extended area of the northern hemisphere centered on the United States. The data are a subset of data available from the Global Volcanism Program, Smithsonian Institution at . This file is a replacement for the April 2004 map layer.

CO-OPS has been involved with tsunami warning and mitigation since the Coast & Geodetic Survey started the Tsunami Warning System in 1948 to provide warnings to the Hawaiian Islands. After the December 2004 Indian Ocean tsunami, CO-OPS was tasked to coordinate with the NOAA Tsunami Warning Centers in upgrading existing stations with new Data Collection Platform (DCP) and communications technology and with expanding the tsunami warning capabilities of the NWLON. Work began in 2005 to upgrade 33 existing water level sand install 16 new stations from the Pacific Ocean to the Caribbean Sea by October 2006. As of September 2006, all 33 upgrades are complete, as well as 15 of the 16 new installations. As of October...

This map layer shows tornado tracks in the United States, Puerto Rico, and the U.S. Virgin Islands, from 1950 to 2008. Statistical data were obtained from the National Weather Service, Storm Prediction Center (SPC). The SPC data originate from the Severe Thunderstorm Database and the National Oceanic and Atmospheric Administration (NOAA) Storm Data publication.

This Historical North Atlantic and Eastern North Pacific Tropical Cyclone Tracks file contains the 6-hourly (0000, 0600, 1200, 1800 UTC) center locations and intensities for all subtropical depressions and storms, extratropical storms, tropical lows, waves, disturbances, depressions and storms, and all hurricanes, from 1851 through 2008.

This map layer contains locations and information on faults and associated folds, in the United States, that are believed to be sources of significant earthquakes (those of magnitude 6 or greater) during the past 1,600,000 years.

This map layer shows seismic hazard in the United States. The data represent a model showing the probability that ground motion will reach a certain level. This map layer shows peak horizontal ground acceleration (the fastest measured change in speed, for a particle at ground level that is moving horizontally due to an earthquake) with a 10% probability of exceedance in 50 years. Values are given in %g, where g is acceleration due to gravity, or 9.8 meters/second^2. The lines of equal hazard, which are the lines between the polygons, were determined by interpolating from a grid of equally spaced points in latitude and longitude. Each point was weighted based on the seismic hazard at that location. The grid spacing...

These data are a digital version of U.S. Geological Survey Professional Paper 1183, Landslide Overview Map of the Conterminous United States. The map and digital data delineate areas in the conterminous United States where large numbers of landslides have occurred and areas which are susceptible to landsliding. Because the data are highly generalized, owing to the small scale and the scarcity of precise landslide information for much of the country, they are unsuitable for local planning or actual site selection. This National Atlas data set was previously distributed as Digital Representation of the Landslide Overview Map of the Conterminous United States.

NGDC maintains a catalog of global volcano locations obtained from the Smithsonian Institution. The catalog contains data on the volcano location, elevation, volcano type, date of the last known eruption, and the certainty of Holocene volcanism.
