seismic z factors and intensity provinces of iranian earthquakes.

چکیده
based on, historical seismicity, position of 19-century instrumental epicenters, fault zones, relation of seismicity with active faults, and structural geology, statistics of earthquake activites, model studies for estimation of acceleration, and other information of intensities of iranian earthquakes, and for simplicity in the usage, the country is divided into two intensity provinces. in the first province, an earthquake with intensity viii or more on modified mercalli scale is probable ,and for this province the seismic z factor of 1 is suggested. most of iranian major cities are located within this province. in the second province, an earthquake with intensity vii or less is probable; for this province the seismic z factor of 0.75 is suggested. the cities of esfahan, abadan, khonin-shahr,(old khoram-shahr), zabol,bijar, miandoab, and takab are located within the second province.

15 صفحه اولSeismic Radiation From Simple Models of Earthquakes
We review some basic features of shear wave generation and energy balance for a 2D antiplane rupture. We first study the energy balance for a flat fault, and for a fault that contains a single localized kink. We determine an exact expression for the partition between strain energy flow released from the elastic medium surrounding the fault, radiated energy flow and energy release rate. This bal...
متن کاملFactors Affecting Energy Intensity in Provinces of Iran: Bayesian Averaging Approach
The identification of the most important factors affecting energy intensity with the aim of controlling and managing energy consumption is an important topic. Findings of different empirical studies on the factors affecting energy intensity are inconsistent and this raises uncertainty about the employed models. One of the techniques that conform to these uncertainty conditions of the model is t...
