The Collaboratory for the Study of Earthquake Predictability (CSEP) aims to advance earthquake research by rigorous testing of earthquake forecast hypotheses. As in other disciplines, such hypothesis testing requires carefully designed experiments that meet certain requirements: they should be reproducible, fully transparent, and conducted within a controlled environment. CSEP has begun buildin...

INTRODUCTION In recent years, several massive earthquakes have occurred across the globe. Multidetector computed tomography (MDCT) is reliable in detecting spinal injuries. The purpose of this study was to compare the features of spinal injuries resulting from the Sichuan earthquake with those of non-earthquake-related spinal trauma using MDCT. METHODS Features of spinal injuries of 223 Sichu...

Abstract Urbanization can be a challenge and an opportunity for earthquake risk mitigation. However, little is known about the changes in exposure (for example, population urban land) to earthquakes context of global urbanization, their impacts on fatalities earthquake-prone areas. We present analysis size land area areas from 1990 2015, earthquake-related fatalities. found that more than two t...

Discrete time-varying autoregressive moving average (ARMA) models are used to describe realistic earthquake ground motion time histories. Both amplitude and frequency nonstationarities are incorporated in the model. An iterative Kalman filtering scheme is introduced to identify the time-varying parameters of an ARMA model from an actual earthquake record. Several model verification tests are pe...

Earthquake affected households too often insufficiently apply seismic construction knowledge during reconstruction. This study aims to assess what degree safety guidelines have found their way practice in Nepal. Differences are explored between communities the Gorkha and Okhaldhunga districts, which received differing levels of technical assistance following 2015 earthquakes. Seismic resistance...

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...

AIMS/INTRODUCTION We investigated impacts of the Great East Japan Earthquake on diabetic patients and characterized those with disaster-susceptible diabetes. MATERIALS AND METHODS We enrolled 497 diabetic patients who had been followed at hospitals in devastated areas. We collected metabolic parameters prospectively, 1 and 3 months after the earthquake, and retrospectively for pre-earthquake ...

The phases that must be completed so a building damaged in earthquake struck Zagreb on 22 March 2020 can renovated and strengthened to the required level of seismic resistance are presented paper. All therefore presented, starting from rapid then detailed inspection, continuing with preparation structural condition assessment report, renovation design and, finally, ending realisation work exper...

We show possible scenarios for the occurrence of M ~ 7 interplate earthquakes prior to and following the M ~ 9 earthquake along the Japan Trench, such as the 2011 Tohoku-Oki earthquake. One such M ~ 7 earthquake is so-called the Miyagi-ken-Oki earthquake, for which we conducted numerical simulations of earthquake generation cycles by using realistic three-dimensional (3D) geometry of the subduc...

At 14:46 on March 11, 2011, the magnitude-9.0 earthquake attacked Sendai and neighboring cities distributed along the northeast coast of Honshu Island, Japan. Its epicenter is located 130 km east of Sendai (Fig. 1). Unfortunate ly, the strong earthquake generated devastating tsunamis that destroyed many towns and villages near the seashore in Iwate, Miyagi, and Fukushima prefectures. The natura...
