In this study, we develop stochastic random-field slip models for the 2011 Tohoku earthquake and conduct a rigorous sensitivity analysis of tsunami hazards with respect to the uncertainty of earthquake slip and fault geometry. Synthetic earthquake slip distributions generated from the modified Mai-Beroza method captured key features of inversion-based source representations of the mega-thrust e...

Parallel manipulators are increasingly used in new applications by exploiting their better characteristics with respect to those of serial manipulators, such as higher stiffness, velocity and acceleration, payload. In this paper, experimental results are presented of a novel application of a 3-DOF CaPaMan (Cassino Parallel Manipulator) prototype to simulate point seismograms and 3D earthquake m...

The 2011 off the Pacific coast of Tohoku earthquake (Mw9.0), which produced many strong motion records, provides an opportunity to examine the characteristics of strong ground motion from a gigantic earthquake. In this paper, the preliminary analysis of the ground motion attenuation, spectral shape and duration was performed using the selected strong motion records of the earthquake. The result...

Because of the availability of high-resolution satellite imagery, remote sensing data has become an attractive source of data for identifying post-earthquake damage. Recently, several semiautomated methods for earthquake damage detection have been developed. These methodologies fall into two general categories: change detection and thematic classification. In change detection, both preand post-...

Here we demonstrate a model that combines Tweets following significant earthquakes with basic site and earthquake characteristics to produce a rapid estimate of the ground shaking intensity. We used all geo-tagged Tweets around the world containing the keyword “earthquake” or “tsunami” in several languages that occurred in the first 10 minutes following Japanese earthquakes of magnitude 6 or gr...

Among various indices of earthquake ground motions, the maximum amplitude value and frequency content have been regarded as the most important indices for earthquake engineering. These indices are strongly affected by local site conditions. Also the fact that the duration of earthquake ground motion differs from site to site even during the same earthquake has been noticed by many researchers. ...

In our recent papers we applied fractal methods to extract the earthquake precursory signatures from scaling characteristics of the ULF geomagnetic data, obtained in a seismic active region of Guam Island during the large earthquake of 8 August 1993. We found specific dynamics of their fractal characteristics (spectral exponents and fractal dimensions) before the earthquake: appearance of the f...

Research concerning the impact of earthquake victims' individual behavior and its association with earthquake-related injuries is lacking. This study examined this relationship along with effectiveness of earthquake rescue measures. The six most severely destroyed townships during the Lushan earthquake were examined; 28 villages and three earthquake victims' settlement camp areas were selected ...

The 2014 Ms 6.5 (Mw6.1) Ludian earthquake occurred in the eastern Sichuan-Yunnan border region of western China. This earthquake caused much more severe engineering damage than the usual earthquakes with the same magnitude in China. The National Strong Motion Network obtained large set of ground motion recordings during the earthquake. To investigate the engineering interested characteristics o...
