The Wenchuan Earthquake on May 12, 2008, devastated a vast area in Sichuan, China. The swift rescue and disaster management measures of the Chinese government have been supported by radar remote sensing from the very beginning. The new high-resolution synthetic aperture radar (SAR) satellites, like COSMO-SkyMed and TerraSAR-X, have been used for damage assessment and rapid mapping. Unfortunatel...

S U M M A R Y Recent seismological observations suggest the existence of a ≈150-km-thick density-stratified layer with a P-wave velocity gradient that differs slightly from PREM. Such a structure can only be caused by a compositional gradient, effects of a slurry or temperature being too small and probably the wrong sign. We propose a stably stratified, variable concentration layer on the liqui...

The Mw 7.3 1995 Aqaba earthquake is the largest instrumental earthquake along the Dead Sea Fault. We complement previous seismological studies by analyzing co-seismic ground displacement from differential interferometry computed from ERS images spanning 3 different areas. They are compared with a synthetic model derived from seismological study. Only far-field deformation related to the main su...

This study discusses a new workflow for fracture characterization and modeling using geophysical (microseismic and 3D surface seismic) data along with independent reservoir information (such as well logs). The framework is ideally suited for unconventional environments such as shale and tight reservoirs where modern technologies such as the use of hydraulic fracturing and passive seismic monito...

A large scale hydraulic injection was conducted at the Australian Hot Dry Rock site in November and December, 2003 in order to develop a commercial size underground heat exchanger. A Japanese seismic team set up the seismic network and data acquisition system, and carried out microseismic monitoring during the period in co-operation with the Australian teams. On-site analysis was done as an alm...

Bilal U. Haq and his co-workers have completed an important update of the chronology of coastal onlap and eustatic fluctuations in Mesozoic and Cenozoic time (1). Seismic stratigraphic results are augmented in the new charts by outcrop and well-log studies to document an impressive total of 119 sea level cycles since the beginning of the Triassic. In addition, the Cretaceous results have been p...

When redundancy of seismic data exists factorial cokriging enables the estimation of (1) a common part, based on the common spatial behavior, and (2) the differences relative to the common part of the input data. Coléou (2002) first introduced the automatic implementation of factorial co-kriging (AFACK) as a filtering technique for the time-lapse (4D) processing sequence. It was specifically de...

We use Interferometric Synthetic Aperture Radar (InSAR) data to derive continuous maps for three orthogonal components of the co-seismic surface displacement field due to the 1999 Mw7.1 Hector Mine earthquake in southern California. Vertical and horizontal displacements are both predominantly antisymmetric with respect to the fault plane, consistent with predictions of linear elastic models of ...

s the use of 3D seismic interpretation continues to become part of the main stream work process with the industry, visualization techniques also continue to evolve as software and hardware improves. In the past 10 years, volume rendering tools have been progressively adopted by the geophysical community as the emergence of high-end graphics workstations with 3D texture capabilities made real-ti...
