Imaging sub-centimeter ground deformations from space

Date and time Dec 07, 2006
from 04:10 PM to 05:00 PM
Location Mclennan Physics (MP) 102
Host Sabine Stanley

Matthew Pritchard

We use Interferometric Synthetic Aperture Radar (InSAR) to create images of surface deformation with sub-centimeter accuracy spanning nearly 1 million square kilometers of South America with a pixel spacing of order ten meters.  The talk will focus on how these observations, combined with other geophysical data, provide insights into the earthquake cycle (including evidence of a "silent" earthquake), and reveal magma movements at several supposedly dormant volcanoes.  I will also touch upon the insights from these observations into other processes such as groundwater movements, glacial flow, and mining-induced deformation.
