Abstract Catastrophic landslides are often preceded by slow, progressive, accelerating deformation that differs from the persistent motion of slow‐moving landslides. Here, we investigate the motion of a landslide that damaged 12 homes in Rolling Hi

Due to the limited resolution at depth of geodetic and other geophysical data, the geometry and the loading rate of the ramp‐décollement faults below the metropolitan Los Angeles are poorly understood. Here we complement these data by assuming con

An 8 year archive of Envisat synthetic aperture radar (SAR) data over a 300 × 500 km2 wide area in northwestern Tibet is analyzed to construct a line‐of‐sight map of the current surface velocity field. The resulting velocity map reveals (1) a ve

Tectonic Deformation and Surface Processes of the Tibetan Plateau Constrained by Time Series Analysis of Sentinel-1 InSAR Data

Autor: Simran Sangha, Susan M. Owen, Gilles Peltzer, Robert Zinke, David Bekaert, Eric J. Fielding

We quantify deformation patterns resulting from tectonic motions and surface processes across the central Tibetan Plateau (29–45ºN, 83–92ºE) since late 2014 using ascending and descending passes of the Sentinel-1A and -1B radar satellites. The
