Remote Sensing Technologies For Earthquake And Tsunami Disaster Management

This research highlights the use of remote sensing technologies in disaster management, notably post-earthquake/tsunami damage detection due to the 2003 Bam Earthquake and the 2004 Indian Ocean Tsunami, and seismic risk assessment based on land use classification in Metro Manila, the Philippines (Pictures attached).

These results will be presented at the 2nd Asia Conference on Earthquake Engineering "Seismic Hazards and Damage Mitigation in the Asian Region" held in Manila, Philippines from March 10-11, 2006.

In the recent few years, large scale earthquakes and tsunamis brought tremendous damages to urban and rural areas in the world, especially in Asia. It is also pointed out that rapid expansion of urban areas in developing countries has made the areas more vulnerable to various natural disasters. Thus, damage assessments before and after disasters have attracted significant attentions among researchers and practitioners of disaster management. Recent advancements in remote sensing and its application technologies made it possible to use remotely sensed imagery data for assessing vulnerability of an area and for capturing the damage distribution due to disasters.

To obtain pre- and post-event information on built and natural environment, several methods exist, such as field survey, airborne remote sensing, and satellite remote sensing. Because of its capacity to cover a vast area in one acquisition time, satellite remote sensing has been a very powerful tool to monitor the condition of the earth surface. High-resolution satellite imagery, which has become available in the last few years, made satellite remote sensing more useful in disaster management since even damage status of individual buildings can be identified without visiting the sites of disasters.

Applications of satellite imagery to post-disaster damage detection are demonstrated for the 2003 Bam, Iran, earthquake and the 2004 Indian Ocean Tsunami. Application of satellite imagery for land use classification and seismic risk assessment is also presented for Metro Manila, the Philippines as an example.
