PURPOSE To investigate the patterns of immediate seismic deaths and post-earthquake mortality changes in the disaster area after the September 21, 1999 Taiwan earthquake. METHODS We used the data of 1826 seismic deaths to elucidate the immediate seismic effects on mortality patterns, and to determine the association between seismic death rates and house damage among 23 townships in the disast...

BACKGROUND The effect of natural disasters on secondary sex ratio (SSR) and perinatal outcomes has been suggested. This study aimed to examine effects of the Great East Japan Earthquake on perinatal outcomes using vital statistics of Japan. METHODS Birth registration data from vital statistics of Japan between March 2010 and March 2012 were used. Pregnant women who experienced the earthquake ...

A numerical simulation study is conducted to examine the effect of a large outerrise earthquake on seismic cycle of large interplate earthquakes in a subduction zone. A model of 2D uniform elastic half-space is set up to exactly evaluate static elastic interactions. The frictional force acting on a plate interface is assumed to obey a laboratory-derived rateand state-dependent friction law. The...

China is one of the countries with high strong earthquakes, which have a profound effect on China. Wenchuan earthquake caused more than 87 thousand deaths and a direct economic loss of 845.1 billion RMB in May 2008. Earthquake risk communication (ERC) is the effective way to achieve the strategic objective of earthquake risk reduction, but a sound platform for ERC has not been established in Ch...

In accordance with the Seismo-Geothermics theory about methods of intracrustal strong earthquake and volcano prediction, we use the ANSS earthquake catalogue from the Northern California earthquake data center and the EMSC earthquake catalogue from the European-Mediterranean Seismological Centre to study the seismic activities of the Turkish Branch Seismic Cone in the Mediterranean Seismic Cone...

This paper investigates the elastic-plastic seismic behavior of long span cable-stayed steel bridges through the plane finite-element model. Both geometric and material nonlinearities are involved in the analysis. The geometric nonlinearities come from the stay cable sag effect, axial force-bending moment interaction, and large displacements. Material nonlinearity arises when the stiffening ste...

BACKGROUND Although acute coronary syndrome (ACS) and stroke are known to increase after earthquake, few data exist regarding the effect of earthquake on these cardiovascular events in rural areas. METHODS AND RESULTS The Noto Peninsula earthquake with a magnitude of 6.9 occurred at 9:45 a.m. on 25 March 2007. The first case of ACS occurred approximately 15 min later, whereas cerebral hemorrh...

The long-term evolution of scaling (fractal) characteristics of the ULF geomagnetic fields in the seismoactive region of the Guam Island is studied in relation to the strong (Ms = 8.0) nearby earthquake of 8 August 1993. The selected period covers 10 months before and 10 months after the earthquake. The FFT procedure, Burlaga-Klein approach and Higuchi method, have been applied to calculate the...

In our previous papers we have shown that the fractal (monofractal) dimension (Do) showed a significant increase before the Guam earthquake occurred on 8 August, 1993. In order to have a further support to this precursory effect to the general rupture (earthquake) we have carried out the corresponding multifractal analysis (by means of detrended fluctuation analysis) for the same data to study ...

The design earthquake motion is often defined by response spectra. To check the seismic capacity of designed structures, however, it is necessary to perform dynamic analysis using earthquake motion (time history) which is compatible with the design spectra. In this regard, the phase characteristic of earthquake motion is one of the most important issues in addition to that of the amplitude char...
