The 2004 Great Sumatra-Andaman earthquake had an average source duration of about 500 sec. and a rupture length of 1 ,200–1,300 km. The seismic moment, M0, determined with a finite source model, was 6.5 1022 N-m, which corresponds to Mw=9.18. Allowing for the uncertainties in the current M0 determinations, Mw is in the range of 9.1 to 9.3. The tsunami magnitude Mt is 9.1, suggesting that the ov...

Owners of building portfolios in earthquake country have several data-related seismic risk mitigation concerns: Before an earthquake, they need to know the locations and seismic characteristics of their buildings to know which might pose a potential seismic risk. They also need the ability to assess and prioritize riskmitigation efforts, and to develop emergency response plans. Immediately afte...

A distinct difference of the earthquake activity in megathrust subduction zones is pointed out, concerning seismic segmentations in the vicinity of Japan—that is, the apparent distribution of earthquake hypocenters characterized by Along-dip Double Segmentation (ADDS) and Along-strike Single Segmentation (ASSS). ADDS is double aligned seismic-segmentation of trench-ward seismic segments along t...

PURPOSE This study longitudinally investigated the changes of depressive symptoms among adolescent survivors over 2 years and a half after the 2008 Wenchuan earthquake in China, as well as the predictive effects of demographic characteristics, earthquake exposure, negative life events, social support, and dispositional resilience on the risk of depressive symptoms at two time points after the e...

Cities are among the most fragile biological settlements due to their complex internal structure and the influence by different variables. Given the realities of these settlements, in the event of devastating events such as earthquakes, these cities are definitely more fragile; consequently, returning to normal life seems to be much longer and costly. Therefore, considering the importance of th...

This paper examines the effect of relative geophysical earthquake risk on housing prices in the Bay Area. The data concludes that the effect of risk on prices is much more significant today than it was prior to the 1989 Loma Prieta earthquake. Evidence also suggests that the 1994 Northridge quake has played a role in shaping the time trend of the impact of this risk factor. Several different sc...
