The 2008 Wenchuan earthquake and associated co-seismic landslide was the most recent expression of the rapid deformation and erosion occurring in the eastern Tibetan Plateau. The erosion associated with co-seismic landslides balances the long-term tectonic uplift in the topographic evolution of the region; however, the quantitative relationship between earthquakes, uplift, and erosion is still ...

SMIP94 Seminar Proceedings Abutment stiffnesses are determined directly from the earthquake motions recorded at the US 1011 Painter Street Overpass using a simple equilibrium-based approach without finite-element modeling of the structure or the abutment-soil systems. The calculated abutment stiffnesses, which include the effects of soil-structure interaction and nonlinear behavior of the soil,...

The current situation in earthquake space research indicates a few phenomena, related with earthquake: Earth's deformation, surface temperature, gas and aerosol content, electromagnetic disturbances in ionosphere. Both horizontal and vertical deformations scaled about tens centimetres and meters after the shock. Such deformations are recorded by InSAR technique with confidence. Pre-earthquake d...

Manual analysis of LiCSAR deformation data in tectonic zones and timely detection pre-earthquake anomalous activity are very time-consuming. To solve this problem, an LiCSAR-based anomaly detector seismic interferometric synthetic aperture radar (LADSDIn) is constructed article. LADSDIn can automatically detect extract zones. modeled by learning the spatiotemporal characteristics MTInSAR time s...

On the 26th December 2003 an earthquake with MW=6.5 shook a large area of the Kerman Province in Iran. The epicenter of the devastating earthquake was located near the city of Bam. This paper described the application of differential synthetic aperture radar interferometry (D-INSAR) and ENVISAT ASAR data to map the coseismic surface deformation caused by the Bam earthquake including the interfe...

After an earthquake, the earliest deformation signals are not expected to be carried by the fastest (P) elastic waves but by the speed-of-light changes of the gravitational field. However, these perturbations are weak and, so far, their detection has not been accurate enough to fully understand their origins and to use them for a highly valuable rapid estimate of the earthquake magnitude. We sh...

[1] Dilatational source deformations associated with two unusual M 3+ earthquakes in the area of the 2004–2008 Yellowstone, WY, accelerated uplift episode were identified through detailed analysis of moment tensor inversions. Pressurized hydrothermal fluids are suggested to be associated with the dilatational source processes of these unusual earthquakes, which is consistent with the mechanism ...

Natural fault surfaces exhibit roughness at all scales, with root-mean-square height fluctuations of order 10−3 to 10−2 times the profile length. We study earthquake rupture propagation on such faults, using strongly rate-weakening fault friction and offfault plasticity. Inelastic deformation bounds stresses to reasonable values and prevents fault opening. Stress perturbations induced by slip o...

Baer, G., Shamir, G., Sandwell, D., Bock, Y. 2001. Crustal deformation during 6 years spanning the M w = 7.2 1995 Nuweiba earthquake, analyzed by Interferometric Synthetic Aperture Radar. Isr. J. Earth Sci. 50: 9–22. The November 22, 1995, M w = 7.2 Nuweiba earthquake occurred along one of the left-stepping segments of the Dead Sea Transform in the Gulf of Elat (Aqaba). We examine the surface d...

Great earthquakes rarely occur within active accretionary prisms, despite the intense long-term deformation associated with the formation of these geologic structures. This paucity of earthquakes is often attributed to partitioning of deformation across multiple structures as well as aseismic deformation within and at the base of the prism (Davis et al., 1983). We use teleseismic data and satel...
