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...

This paper presents a suitable and quick way to choose earthquake records in non-linear dynamic analysis using optimization methods. In addition, these earthquake records are scaled. Therefore, structural responses of three different soil-frame models were examined, the change in maximum displacement of roof was analyzed and the damage index of whole structures was measured. The soil classifica...

The Web not only distributes classically organized teaching material such as overheads, lecture notes and books, but also encourages new ways of publication and provides the means for content which could not have been printed on paper. In the article we present a tool for teaching earthquake engineering an Earthquake Engineering Slide Information System (EASY). It uses information technology to...

STUDY OBJECTIVE To make a descriptive analysis of the frequency and the type of thorax and lung injuries among the casualties of the two devastating earthquakes that occurred in Turkey in 1999. DESIGN Records of the hospitalized patients injured in the earthquakes were examined retrospectively. RESULTS Among the total of 356 hospitalized patients, 21 (9.7%) in the Izmit earthquake and 6 (7....

High-rise flexible-frame buildings are commonly considered to be resistant to shaking from the largest earthquakes. In addition, base isolation has become increasingly popular for critical buildings that should still function after an earthquake. How will these two types of buildings perform if a large earthquake occurs beneath a metropolitan area? To answer this question, we simulated the near...

An automated, real-time, multiple sensor data source relying and globally applicable earthquake loss model and visualiser is desirable for post-event earthquake analysis. To achieve this there is a need to support rapid data ingestion, loss estimation and integration of data from multiple data sources and rapid visualisation at multiple geographic levels. In this paper, the design and developme...

OBJECTIVES To investigate the prevalence of probable post-traumatic stress disorder (PTSD), anxiety and depression, and to identify risk factors related to these mental disorders among hard-hit survivors 1 year after the earthquake in Wenchuan, China. STUDY DESIGN : Cross-sectional survey. METHODS A door-to-door survey covering the entire temporary community was undertaken to investigate 11...

OBJECTIVE On 11 March 2011, the Great East Japan Earthquake struck off Japan. Although some studies showed that the earthquake increased the risk of pneumonia death, no study reported whether and how much a tsunami increased the risk. We examined the risk for pneumonia death after the earthquake/tsunami. DESIGN This is an ecological study. SETTING Data on population and pneumonia deaths obt...

OBJECTIVE To examine the effects of a huge tsunami resulting from the Great East Japan Earthquake on blood pressure (BP) control and glycaemic control in diabetic patients. DESIGN A retrospective study. SETTING Tohoku University, Japan. PARTICIPANTS 63 patients were visiting Rikuzentakata Hospital for diabetic treatment before the earthquake and returned to the clinic in July after the ea...

Direct body waves and fundamental surface waves are calculated for a credible, hypothetical great earthquake on the San Andreas Fault. The prototype event assumed is the Fort Tejon earthquake of January 9, 1857. Amplitudes and durations of long-period ground motion ( T > 1 sec) are found for a receiver in downtown Los Angeles. Calculations are carried out for various epicenters, dislocation pro...
