Localization of the gravity field and the signature of glacial rebound
Article Abstract:
Research shows that the unique negative free-air gravity anomaly over Hudson Bay, Canada, is due to incomplete post-glacial rebound. The region is correlated to the Laurentide ice sheet's location but is also characterized by above-average mantle seismic velocities. The gravity low over Hudson Bay has an anomalously high amplitude where the predicted relaxation times are longest and where the Laurentide ice load's power is greatest in the spectral band.

Interseismic strain accumulation and the earthquake potential on the southern San Andreas fault system
Article Abstract:
High-resolution measurements of interseismic deformation across the southern San Andreas fault system are presented using a well-populated catalogue of space-borne synthetic aperture radar data. The measurements point to a nearly equal partitioning of deformation between the southern San Andreas and San Jacinto faults, with a pronounced asymmetry in strain accumulation with respect to the geologically mapped fault traces.

Three-dimensional deformation caused by the Bam, Iran, earthquake and the origin of shallow slip deficit
Article Abstract:
The full vector displacement field due to the Bam, Iran, earthquake of moment magnitude 6.5 is derived using radar data from the Envisat satellite of the European Space Agency. Analysis of surface deformation indicates that most of the seismic moment release along the 20-km-long strike-slip rupture occurred at a shallow depth of 4-5 km, yet the rupture did not break the surface.
