They can be used in monitoring and management, mitigation and recovery efforts. They also offer an excellent opportunity for creating a long term database for the purpose of risk assessment and relief management. Recommentation As for coastal shoreline erosion study, the satellite data should be in Earthquake Damage Assessment, September 1213, 2005, Japan
