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...

Probabilistic seismic hazard analysis is a technique for estimating the annual rate of exceedance of a specified ground motion at a site due to the known and suspected earthquake sources. A Monte-Carlo approach is utilized to estimate the seismic hazard at a site. This method uses numerous resampling of an earthquake catalog to construct synthetic catalogs to evaluate the ground motion hazard a...
