D. Massonnet W. Thatcher 1997 <div class=""><div class="article-section__content en main"><p>Satellite radar interferometric images of Long Valley caldera show a pattern of surface deformation that resembles that expected from analysis of an extensive suite of ground-based geodetic data. Images from 2 and 4 year intervals respectively, are consistent with uniform movement rates determined from leveling surveys. Synthetic interferograms generated from ellipsoidal-inclusion source models based on inversion of the ground-based data show generally good agreement with the observed images. Two interferograms show evidence for a magmatic source southwest of the caldera in a region not covered by ground measurements. Poorer image quality in the 4 year interferogram indicates that temporal decorrelation of surface radar reflectors is progressively degrading the fringe pattern in the Long Valley region.</p></div></div> application/pdf 10.1029/97GL02597 en American Geophysical Union Crustal deformation at long Valley Caldera, eastern California, 1992-1996 inferred from satellite radar interferometry article
