BACKGROUND Time discounting refers to the fact that the subjective value of a reward decreases as the delay until its occurrence increases. The present study investigated how time discounting has been affected in survivors of the magnitude-8.0 Wenchuan earthquake that occurred in China in 2008. METHODOLOGY Nineteen earthquake survivors and 22 controls, all school teachers, participated in the...

[1] The 2011, Mw9.0 Tohoku earthquake was followed by an abundant amount of seismicity providing a unique opportunity to analyze the triggering mechanism of great earthquakes. Although the Tohoku earthquake occurred close to a dense seismic network, many aftershocks that occurred in the first few hours after the mainshock are not recorded in the earthquake catalogs. Here we use a template wavef...

This study develops a novel simulation-based procedure for the estimation of the likelihood that seismic intensity (in terms of spectral acceleration) and tsunami inundation (in terms of wave height), at a particular location, will exceed given hazard levels. The procedure accounts for a common physical rupture process for shaking and tsunami. Numerous realizations of stochastic slip distributi...

Dear Editor-in-Chief On January 28, the city of Khoy (the northwest of Iran) was struck by a strong earthquake with a magnitude of 5.9 on the Richter scale at 21:44:44 and a depth of 7 km, X: 45.01 and Y: 38.05 (1). This earthquake occurred 117 kilometers from Urmia, the capital of the West Azerbaijan Province. Over 370,000 people were affected by this earthquake, which resulted in three death...

This paper presents an analysis of the distribution of earthquake magnitudes for the period 1990–1998 in a broad area surrounding the epicenter of the 1995 Kobe earthquake. The frequency–magnitude distribution analysis is performed in a nonextensive statistical physics context. The nonextensive parameter qM, which is related to the frequency-magnitude distribution, reflects the existence of lon...

BACKGROUND The study was implemented to examine the relationship between traumatic experiences and longitudinal development of mental health for children and adolescents who survived the 2008 Sichuan earthquake. METHODS Using the method of multistage systematic sampling, 596 children aged between 8 and 16 years were randomly selected from severely affected areas of the earthquake. These child...

Over 2000 earthquakes happen every year in Japan, so that this country is often called earthquake-ridden (Government of Japan, 2006). There exists a serious problem to prevent the occurrence of earthquake-induced disasters, such as fire, short-circuits, gas leakage, etc. With the recent advent of nation-wide telecommunication networks, real-time earthquake information can be received at every h...

AIMS While previous studies reported a short-term increase in individual cardiovascular disease (CVD) after great earthquakes, mid-term occurrences of all types of CVDs after great earthquakes are unknown. We addressed this important issue in our experience with the Great East Japan Earthquake (11 March 2011). METHODS AND RESULTS We retrospectively examined the impact of the Earthquake on the...

In recent years, earthquakes have frequently occurred all over the world, which caused huge casualties and economic losses. It is very necessary and urgent to obtain the seismic intensity map timely so as to master the distribution of the disaster and provide supports for quick earthquake relief. Compared with traditional methods of drawing seismic intensity map, which require many investigatio...
