Volcano Deformation Modeling Using Radar Interferometry: A Mechanical Model of the Large-deformation 2005Sierra Negra Volcanic Eruption Derived from InSARMeasurements

This book is Sang-Ho Yun's Ph.D. work at Stanford University. It contains radar image processing parts and geophysical modeling parts. The data processing parts introduce an optimal algorithm to recover missing regions of digital elevation model (DEM) and an algorithm to form an interferometric radar image of large ground deformation. The geophysical modeling parts describe a new method to estimate the detailed shape and the pressure of underground cracks filled with liquid suchas low viscous magma. The new techniques in both parts are applied to volcano deformation modeling of the eruption event at Sierra Negra volcano in Galapagos Islands in October 2005. The eruption event was preceded by an earthquake of magnitude 5.4 and caused one of the most complex deformation pattern for radar imaging and geophysical modeling. This book shows a good example of volcano deformation modeling using radar images in a mechanically consistent way.

Dr. Sang-Ho Yun is currently working for the Jet PropulsionLaboratory in Pasadena, California. He worked for theU.S. Geological Survey as an NRC Postdoctoral Fellow. He receivedhis PhD in geophysics, MS in electrical engineering, and MS ingeophysics, all from Stanford University. He earned his BS ingeology from Seoul National University
