Natural Hazards in Southern California
The Integrated Multi-Hazards Demonstration Project in Southern California will show how integrating information and products about multiple hazards can reduce loss of life and property from natural hazards. The unique research and systems capabilities of the USGS provide the science and monitoring needed to address the complex issues associated with natural hazards events, especially interrelated hazards, such as fire, floods, and debris flows, or earthquakes and tsunamis.

Landsat Data Continuity Mission
The USGS and NASA will be teaming up once again on the development, launch, and operation of a "free-flyer" Landsat Data Continuity Mission. The mission includes launching an earth observing satellite and the processing and distribution of the data from the satellite. NASA will have responsibility for procuring the data acquisition capability and the USGS will operate the satellite after a successful launch and check-out and will be responsible for the ingest, archive, processing, and distribution of Landsat-type data products. This capability could become operational early in 2011.
