Chung-Pai Chang   Received M.Sc. degree in Geosciences from National Taiwan University, Taipei, Taiwan, 1996; and Ph.D. degree in Tectonics from Paris VI University (Université Pierre et Marie Curie), Paris, France, 2001.

His academic training extensively employed quantitative methods to investigate geological processes, with a primary focus on determining deformations in orogenic systems. His research interests span structural geology, geological remote sensing, neotectonics, and geohazard studies, specifically in Taiwan, the Indian Himalaya, the Tibetan plateau, and surrounding areas. Over the past two decades, Professor Chang has been dedicated to utilizing remote sensing and space geodetic measurements in studying natural hazards and land surface deformation at the Center for Space and Remote Sensing Research, National Central University.

Professor Chang brings a wealth of international cooperation experience. He has served as the Principal Investigator for various programs, including the Taiwan-French Program, the Taiwan-India Program, the Cross-Strait Cooperation Program, and the Taiwan-Vietnam Program. In recent years, he has actively fostered collaboration with local universities, engaging in overseas teaching, dual-degree programs, and facilitating short-term student internships, yielding noteworthy results.

Using Satellite Remote Sensing Technology and Field Investigations to Study Geological Structure Movements

Satellite remote sensing technology has become a crucial tool for studying geological structure movements. By utilizing techniques such as synthetic aperture radar (SAR) and interferometric SAR (InSAR), researchers can monitor surface deformation and detect subtle changes in tectonic activity. These methods enable the precise measurement of ground displacement caused by earthquakes, landslides, and volcanic activity, providing valuable data for hazard assessment and disaster prevention.

To enhance the accuracy of remote sensing data, field investigations are conducted for validation. By combining satellite observations with on-site geological surveys, researchers can cross-verify findings and improve the reliability of interpretations. Field investigations provide ground truth data, helping to refine remote sensing models and better understand geological processes.

Compared to traditional ground-based surveys, satellite remote sensing offers advantages such as large-scale coverage, high temporal resolution, and accessibility to remote or hazardous areas. As technology advances, integrating remote sensing with field investigations and other geophysical methods will further improve our ability to monitor and mitigate natural disasters related to geological movements.
