From the U.S. Dept. of the Interior:
A new Interior Department website offers the public as well as federal, state and local emergency management communities online maps containing the latest available information on earthquakes, earthquake shakemaps, streamflow data and floods, volcanoes and wildfires, as well as information on severe weather hazards.
The Interior Geospatial Emergency Management System (IGEMS), managed by the department’s Office of Emergency Management, provides ongoing awareness of natural hazards, enabling individuals to monitor and analyze natural hazard events as they occur. Information is presented in an integrated geospatial view that locates these threats with reference data, including various basemaps that can be selected by users. The system utilizes data from Interior bureaus, such as the U.S. Geological Survey as well as data provided by the National Weather Service and other authoritative sources.
IGEMS is the next generation replacement for the Natural Hazards Support System that had been in operation since 2003, supporting a significant customer base that registered more than 8 million hits a month.
