The irregularity and long time intervals between earthquakes are factors contributing to reduced awareness about earthquake risks among the public and government officials and hence to reduced allocation of resources for their mitigation. Moreover, it is not uncommon to see misallocation of resources by non- knowledgeable decision makers and ...

Multi-scale seismicity model for seismic risk
Bulletin of the Seismological Society of America, 1997AbstractFor a general use of the frequency-magnitude (FM) relation in seismic risk assessment, we formulate a multi-scale approach that relies on the hypothesis that only the ensemble of events that are geometrically small, compared with the elements of the seismotectonic regionalization, can be described by a log-linear FM relation.

The chapter presents some aspects of the seismic risk communication within a systemic disaster management system (SDMS) model. Information and communication technology (ICT) plays a key part in managing natural disasters. An example of seismic risk preparedness for the case of preparatory schools in Mexico City has been used to illustrate this feature ...

Large earthquakes could potentially cause extensive property damage, loss of life, and environmental damage as a result of damage to critical facilities. Assessment of seismic risk to critical facilities such as nuclear power plants and chemical plants is not only important from the standpoint of a large capital investment but also because of potential

Microearthquakes and seismic risk
Geologiska Föreningen i Stockholm Förhandlingar, 1978Abstract This paper is presented in the nature of a review of the potential of microearthquake surveys in seismotectonic studies, particularly seismic-risk analyses. Microearthquakes are generally considered as shocks with magnitude less than 3.

Seismic Probabilistic Risk Assessment
2016This chapter presents an overview of the seismic probabilistic risk assessment (PRA) for nuclear power plants. First, the basic concept of seismic PRA and its application to continuous improvement of seismic safety of nuclear power plants are explained. Then, the methodology of seismic PRA for nuclear power plants is explained.

Abstract Seismic risk is calculated by means of recurrence periods, obtained from least squares relations between number of earthquakes and magnitude. This method is described and applied to Fennoscandia. The results, summarized in tabular form, give the seismic risk for 54 regions, each comprising 2° in latitude and 2° in longitude, and for the ...

The last 15 years have seen a very rapid increase in the demand for earthquake resistant design of structures not only in the more seismic regions but also in the less earthquake prone areas of northwest Europe, where the engineering profession is being involved in an ever wider range of project types that require earthquake resistant design or ...

Geomorphology and seismic risk
Earth-Science Reviews, 1991Abstract The author analyses the contributions provided by geomorphology in studies suited to the assessment of seismic risk: this is defined as function of the seismic hazard, of the seismic susceptibility, and of the vulnerability. The geomorphological studies applicable to seismic risk assessment can be divided into two sectors: (a) morpho ...

Engineering seismic risk analysis
Bulletin of the Seismological Society of America, 1968Abstract This paper introduces a method for the evaluation of the seismic risk at the site of an engineering project. The results are in terms of a ground motion parameter (such as peak acceleration) versus average return period. The method incorporates the influence of all potential sources of earthquakes and the average activity rates ...
