A Discovery Net project that has been investigating the relationship between macro and micro-scale earthquake deformational processes has successfully developed and tested a geoinformatics infrastructure for linking computationally intensive earthquake monitoring and modelling. Measurement of lateral coseismic deformation is carried out with imageodesy algorithms running on servers at the Londo...

Landslides triggered by strong earthquakes often caused most of the global damage and most of all casualties related to the events, such as shown by the M = 7.7 Peru earthquake in 1970, by the M = 7.6 El Salvador earthquake in 2001 or by the M = 7.4 Khait (Tajikistan) earthquake in 1949. The obvious impact of a landslide on the population is directly related to its movement. Yet, prediction of ...

coupled -shear walls are one of lateral load resisting systems in high and medium rise reinforced concrete buildings. the lateral structural response is exactly dependents on the shear walls behavior; therefore these elements must response well whenundergodifferent load conditions. the structures located in near-source region behave differently compared to those in near-source sites when subjec...

Human response to any adverse situation can be greatly enhanced through training and mind-body experience. Earthquake is one such phenomenon where human response to minimise injuries/deaths is constrained due to disorientation of the victims. People in regions with frequent earthquakes often exhibit better response due to past experience. Training of the mind and body can also be achieved in a ...

At 7:49 am on April 14, 2010, an earthquake (Ms 7.1) originated (33.2°N, 96.6°E) near Jiegu Town, Yushu Tibetan Autonomous Prefecture, Qinghai Province, China. After the earthquake, we analyzed the geological structure of the disaster region based on the “Beijing-1” images. Using the aerial images after earthquake with high resolution (0.4m) and SPOT ortho-images, we monitored urgently the disa...

We report the detection of an earthquake by a space-based measurement. The Gravity Recovery and Climate Experiment (GRACE) satellites observed a +/-15-microgalileo gravity change induced by the great December 2004 Sumatra-Andaman earthquake. Coseismic deformation produces sudden changes in the gravity field by vertical displacement of Earth's layered density structure and by changing the densit...

[1] To examine the effects of branched fault geometry on the dynamics of fault systems in the long term, we perform multicycle simulations on generic faulting models. An explicit finite element algorithm is used to simulate spontaneous dynamic rupture of earthquakes. The fault stress during the interseismic period is evaluated by an analytical viscoelastic model. We find that the fault prestres...

Offshore structures such as jacket platforms have to inevitably be designed against  sever  environmental actions. In seismically active areas these structures also become susceptible to earthquake excitations. Strong ground motions recorded  in recent earthquakes, including the 1995 Kobe, Japan, 1999 Chi-chi, Taiwan and 1999 Kocaeli, Turkey earthquakes, revealed that the dynamic motions in nea...

A major earthquake devastated the Armenian Republic of the Soviet Union on December 7, 1988, resulting in thousands of deaths and injuries. In a postearthquake investigation of three towns seriously affected by the earthquake, we studied earthquake-related injury patterns, made observations on rescue and medical efforts, and postulated certain factors associated with increased morbidity and mor...
