Zhong Lu



Zhong Lu received the B.S. and M.S. degrees from Peking University, Beijing, China, in 1989 and 1992, and the Ph.D. degree from the University of Alaska Fairbanks, Fairbanks, in 1996. He was a physical scientist with United States Geological Survey (USGS) during 1997-2013, and is now a professor and endowed Shuler-Foscue chair at Huffington Department of Earth Sciences, Southern Methodist University, Dallas, Texas, USA (www.smu.edu/dedman/lu). He is a principal investigator of projects funded by NASA, European Space Agency, Japan Aerospace Exploration Agency, German Aerospace Agency, and USGS on the study of land surface deformation using satellite interferometric synthetic aperture radar (InSAR) imagery. His research interests include technique developments of SAR, InSAR, and persistent scatterer InSAR processing and their applications on natural hazard monitoring and natural resource management. He has produced more than 50 lead-authored and 80 coauthored peer-reviewed journal articles and book chapters focused on InSAR techniques and applications. His new book on “InSAR Imaging of Aleutian Volcanoes: Monitoring a Volcanic Arc from Space” was published by Springer in April 2014.



InSAR and its applications to monitor landslides and land subsidence


Satellite radar provides an all-weather, day-and-night imaging capability for monitoring landscape changes. Through interferometric synthetic aperture radar (InSAR) technique, satellite radar imagery can be used to measure ground surface deformation and map land surface characteristics at an unprecedented precision and spatial resolution. This talk introduces the principle of  InSAR imaging and summarizes the revolution of InSAR technology on monitoring landslide and land subsidence.
