A Change in Energy Intensity: Test of Relationship between Energy Intensity and Income in Iran
In this paper we study the long- term trend of energy intensity for Iran. We use a quadratic function of the logarithm of income to take account of the change in trend of energy intensity and test the non-monotonic relationship between energy intensity and income during 1967- 2002 We find that the long-run coefficient on squared income is negative and significant, indicating a change in trend o...
متن کاملEstimation of the Maximum Earthquake Magnitude, mmax
This paper provides a generic equation for the evaluation of the maximum earthquake magnitude mmax for a given seismogenic zone or entire region. The equation is capable of generating solutions in different forms, depending on the assumptions of the statistical distribution model and/or the available information regarding past seismicity. It includes the cases (i) when earthquake magnitudes are...
متن کاملFractal dimension and earthquake frequency-magnitude distribution in the North of Central-East Iran Blocks (NCEIB)
The Gutenberg–Richter parameters (a and b), fractal dimension (DC), and relationships between these parameters are calculated for different regions of the North of Central-East Iran Blocks (NCEIB). The whole examined area (between 34°-36° N and 55°-61° E) is divided into 55 equal square grids. Both the a and b values for the frequency-magnitude distribution (FMD) and the fractal dimension (DC) ...
متن کاملOn Correlation of Seismoscope Response with Earthquake Magnitude and Modified Mercalli Intensity by M. D. Trifunac and A. G. Brady
A quantitative measure of the Modified Mercalli Intensity Scale for earthquakes in ~he western United States has been developed by correlating the peak seismoscope relative displacement response, Sd, with the reported site intensity, IMM. This correlation can be approximated by
متن کاملMagnitude dependence of radiated energy spectra: Far-field expressions of slip pulses in earthquake models
[1] We examine the radiated waves emitted by events on a model fault. The model deterministically produces a complex sequence of events, with a wide range of sizes, from a uniform frictional instability. The spontaneous rupture events emit a rich spectrum of radiated waves as they nucleate, propagate, and decelerate within the complex stress field left by previous events. Two model innovations,...
