In a recent article, Wesnousky (1994) (henceforth referred to as Wesnousky) analyzes seismicity and geologic deformation rates for five faults in southern California and arrives at the conclusion that the characteristic model yields a better description of the earthquake size statistical distribution than the Gutenberg-Richter (G-R) magnitude-frequency law. To analyze earthquake occurrences in ...

Seismic base isolation are devices that used to limit the human and material damage caused by an earthquake. This devices diffuse the energy induced at the time of the earthquake before being transferred to the structure.The base isolated structures when subjected to the near-fault eathquakes which contain long-period velocity pulses that may coincide with the period of base isolated structures...

Active continental margins are the Earth's principal regions of active deformation and significant earthquake hazard. We apply the enhanced method called Scan Synthetic Aperture Radar (ScanSAR) interferometry to quantify active surface deformation in the coastal region of the South American active margin in central Chile between 22° S and 27° S. Here, as in other active margin settings, crustal...

interferometric synthetic aperture radar (insar) technique is valuable tool in monitoring crustal deformation due to its large spatial coverage and high spatial resolutions. in this paper, the intersiesmic crustal deformation occurred before earthquake on august 2012 in ahar-varzegan located in north-west of iran is studied using persistent scattering interferometry. the psi algorithm used in t...

The outrigger arm system and belt truss with braced core in the center of the structure surrounded by belts truss, is an efficient and reliable system for high-rise buildings against severe lateral forces such as earthquake and wind. The purpose of this research is investigating the outrigger arm system and belt truss with the braced core under lateral loads. Another purpose of this research is...

[1] GPS data define a broad zone of present day deformation in the eastern Basin and Range province, western US. Using finite element models with elastic upper crust over viscoelastic lower crust/upper mantle and incorporating earthquake cycle effects, we show that these data are consistent with a model whereby most contemporary fault slip is focused on the Wasatch fault zone. Modeled rates of ...

Stress focusing in a proposed heel-shaped model reasonably explains the occurrence of the largest onland earthquake (MW 7.6) in Taiwan’s history. The epicenter of the mainshock was located in a low-seismicity block, where, historically, large earthquakes have not been documented for the past century. Spatial variations in crustal deformation reported in Global Positioning System surveys suggest...

On 19 January 2020, an Mw6.0 earthquake occurred in Jiashi County, Xinjiang, China. This is a strong that the Kepingtage Belt. The monitoring and inversion of co-seismic post-earthquake will help further understand geometry movement properties this tectonic belt. In study, Sentinel-1A images were used to analyze deformation post-seismic events. Okada elastic dislocation model was invert geometr...

the number of constructed dams has been largely increased due to high demands of water supplies, and earth dams are the most common types since they are more compatible to the environment. nevertheless, the stability of these important structures during earthquakes has to be carefully evaluated and guaranteed. in the past, earth dams usually designed with pure clay core, but in recent decades t...
