Co-Registration of Optically Sensed Images and Correlation (COSI-Corr): an operational methodology for ground deformation measurements

Abstract

Recent methodological progress, Co-Registration of
\nOptically Sensed Images and Correlation, outlined here, makes it
\npossible to measure horizontal ground deformation from optical
\nimages on an operational basis, using the COSI-Corr software
\npackage. In particular, its sub-pixel capabilities allow for accurate
\nmapping of surface ruptures and measurement of co-seismic
\noffsets. We retrieved the fault rupture of the 2005 Mw 7.6
\nKashmir earthquake from ASTER images, and we also present
\na dense mapping of the 1992 Mw 7.3 Landers earthquake of
\nCalifornia, from the mosaicking of 30 pairs of aerial images.
