摘要：In this study the Coda waves application have been investigated to obtain the source and path effects for the Tehran region. Methods are used here to obtain the attenuation of path is normalized method and for an estimate of the magnitude, the length of time coda waves is used. A Reliable estimate of the magnitude and the full examination of magnitude (Mc) from the earthquake catalogs is necessary for any analysis of seismicity, (Habermann, 1987). We used the records of seismic waves from Geophysics Institute of University of Tehran for Mc was calculated as follows. Frankel (1990) used for the first time coda normalized methods to estimate the number of stations. That for inactive areas and are rare and low data this method can be useful. We used recorded accelerograms Kojor of around the epicenters of earthquakes that led to we are calculate the absorption coefficient with using normalized coda waves (Aki, 1980) for all recorded stations that had good signal to noise ratio of quality factor.
