Abstract:
FEMA's Mutihazard Mapping Initiative (MMI) is to maintain a living atlas of
hazards data and map services for advisory purposes supplied from a network of
hazard and base map providers.
The initiative is an implementation of Section 203(k) of the Disaster
Mitigation Act of 2000, which calls for the creation of Multihazard Advisory
Maps, or maps "on which hazard data concerning each type of
... natural disaster is
identified simultaneously for the purpose of showing areas of hazard overlap."
The goals of the initiative are to
- Foster the exchange and collection of geospatial hazards data
- Increase hazard awareness by providing a multihazard mapping capability on
the Internet for advisory purposes
- Encourage data providers to establish standards based services that
facilitate access and distribution of their data for the creating of these
maps.
Data consists of:
- Historical North Atlantic Hurricane Tracks file of Major Storms with Landfall
in the United States
- Historical North Atlantic Tropical Cyclone Tracks
- Landslide Overview Map of the Conterminous United States.
The following data are available derived from the USGS National Atlas
- Landslide Events
- Calderas - Impact Structures
- Craters - Impact Structures
- Fault Lines - Fracture Zones
- Glacial Limits/Extent
- Metamorphism - Facies
- Rocks Types
