ImageCat awarded a contract by Caltech/JPL to conduct research on detecting liquefaction ground failure using satellite imagery

Long Beach, CA - December 10, 2001.   Working as a member of a University of Southern California (USC) research team, ImageCat is studying the use of satellite imagery in detecting post-earthquake liquefaction ground failure. This study is being performed as part of the Global Earthquake Satellite System (GESS) study, a NASA project managed by the Jet Propulsion Laboratory. The objectives of the overall program are to develop a long-term (20-year) plan defining NASA's role in a multi-agency program of observations, information technology and modeling infrastructure that would lead to understanding of faults and fault systems and achieve short-term, targeted earthquake forecasting, in addition to providing information in near real-time in response to natural disasters. The USC/ImageCat team is responsible for addressing liquefaction hazards in this program.

Some of the issues that will be addressed by the USC/ImageCat study include:

  • Data resolution levels needed to detect liquefaction on a small to large scale.
  • Bandwidth of data.
  • Recurrent period of post-disaster observations.
  • Coverage of affected area.
  • Type of coverage, i.e., urban versus rural.

The results from this study will help to identify the future requirements of a satellite designed to facilitate disaster response. A final report for the USC/ImageCat study is expected to be release in early Spring 2002.
