This survey of well-documented repeated fault rupture confirms that some faults have exhibited a "characteristic" behavior during repeated large earthquakes--that is, the magnitude, distribution, and style of slip on the fault has repeated during two or more consecutive events. In two cases faults exhibit slip functions that vary little from earthquake to earthquake. In one other well-documente...

a prerequisite to seismic hazard assessment is to have knowledge of historical and prehistorical earthquakes. to obtain such data, researchers have already practiced different methods including historical seismology, paleoseismology, and recently archaeoseismology. archaeoseismology is a multidisciplinary approach which ideally tries to find the age, epicenter, and magnitude of past earthquakes...

Abstract Seismic events produced by block rotations about vertical axis occur in many geodynamic contexts. In this study, we show that these can be accounted for using the proper theory, namely micropolar and a new asymmetric moment tensor derived. We then apply theory to Kaikōura earthquake (2016/11/14), Mw 7.8, one of most complex earthquakes ever recorded with modern instrumental techniques....

We apply to the observed seismicity of Lesser Antilles a short term earthquake precursor which has been recently found by analysis of synthetic seismicity. The latter was generated by a lattice-type “Colliding Cascades” model of interacting elements. Precursor named ROC depicted premonitory increase of the earthquakes correlation range. Here, this precursor is used as a second approximation to ...

Recent parallel development of improved quantitative methods to analyze intensity distributions for historical earthquakes and of web-based systems for collecting intensity data for modern earthquakes provides an opportunity to reconsider not only important individual historical earthquakes but also the overall characterization of intensity distributions for historical events. The focus of this...

Tsunami hazard can be analyzed from both deterministic and probabilistic points of view. The approach is based on a “credible” worst case tsunami, which often selected historical events in the region study. Within (PTHA, Probabilistic Hazard Analysis), statistical analysis carried out particular regions where records tsunami heights runup are available. In areas these scarce, synthetic series u...

The district of southern California is divided into small cubic cells. Each cell is regarded as a vertex of a random graph, when earthquakes with any values of magnitude occur therein. Successive earthquakes define an edge and a loop. Then, the seismic data are analyzed from the viewpoint of an evolving random network. It is found that the distribution of connectivities in the earthquake networ...

We studied strong-motion spectra observed for three Mw 7.8 to 8.0 earthquakes (the 1985 Michoacan, Mexico; 1985 Valparaiso, Chile; and 1983 Akita-Oki, Japan earthquakes). We determined the decay of spectral amplitude with distance from the station, considering different measures of distance from a finite fault. We compared strong-motion spectra (Fourier acceleration spectra) observed for these ...

OBJECTIVES Natural disasters, which are defined as events causing great damage or loss of life, are events of natural origin unpreventable by human beings that occur in a short period of time and lead to loss of life and property. The aim of the study is to analyze which patient groups and problems at a university hospital after the earthquakes in Van. METHODS For the purposes of this study, ...
