InSAR Captures Rifting and Volcanism in East Africa
In the past decade, synthetic aperture radar interferometric (InSAR) has enjoyed increasing use as a tool for detecting and characterizing surface deformation associated with volcanoes, earthquakes, glaciers, and other geological processes.
Asymmetric Opening and Episodic Faulting in the Asal Rift, Djibouti
Located at the western end of the Aden Ridge, the Asal Rift is the first subaerial opening segment of the ridge propagating into Afar. In November 1978, the rift was the locus of a major seismo-volcanic crisis producing a fissural eruption, 2 m of horizontal extension between the rift shoulders, 0.7 m of subsidence of the inner floor and a number of signs of ground deformation, including up to one meter of slip on large bounding faults and numerous open fissures.
ASF’s User Remote Sensing Access (URSA) became operational on April 28, after months of effort by a dedicated team of developers and testers.
