Automatic Methods for Generating Seismic Intensity Maps
For many years the Modified Mercalli (MM) scale has been used to describe the observed effects of sizeable earthquakes on buildings and people. Initially isoseismal lines of the effects were added to maps by hand. Some objective methods have been proposed eg. DeRubeis et al. [14], Brillinger [2, 3, 4, 6], Wald et al.[33], Pettenati et al. [25]. The work presented here develops such methods furt...
متن کاملProbabilistic Seismic Hazard Assessment of Tehran Based on Arias Intensity
A probabilistic seismic hazard assessment in terms of Arias intensity is presented for the city of Tehran. Tehran is the capital and the most populated city of Iran. From economical, political and social points of view, Tehran is the most significant city of Iran. Many destructive earthquakes happened in Iran in the last centuries. Historical references indicate that the old city of Rey and the...
متن کاملThree-Channel Correlation Analysis: A New Technique to Measure Instrumental Noise of Digitizers and Seismic Sensors
This article describes a new method to estimate (1) the self-noise as a function of frequency of three-channel, linear systems and (2) the relative transfer functions between the channels, based on correlation analysis of recordings from a common, coherent input signal. We give expressions for a three-channel model in terms of power spectral densities. The method is robust, compared with the co...
متن کاملCorrelation between Seismic Intensity Parameters of HHT-Based Synthetic Seismic Accelerograms and Damage Indices of Buildings
In this work, a correlation study between well-known seismic parameters and damage indices is presented. The correlation analysis is first performed on a set of natural seismic signals and afterwards on a set of artificial accelerograms generated from natural records. The artificial seismic signals are generated by a combination of techniques; the Hilbert-Huang transform and an optimization alg...
متن کاملA Method of Expressing Seismic Intensity for a Wider Period Range
The instrumental seismic intensity of Japan Meteorological Agency (JMA) uses three types of filters which consist of high-cut, low-cut and period functions. An extended function of the low-cut filter is used to evaluate the effect of long-period range on seismic intensity in the paper. An asymptotic filter processing of acceleration in the extended function is proposed to express seismic intens...
