EVALUATE OF SOURCE TIME FUNCTION OF ALBORZ REGION ANDSURROUNDING AREA EARTHQUAKES

摘要

The Alborz region is a relatively seismic block within the Alpine-Himalayan Belt. We have compiledsource time function of 31 events of Caspian earthquakes that is obtained from teleseismic bodywaveform modeling. The duration of each subevent with magnitude larger than 5 (Mw >5.0) and depthbetween 4≤ h≤76 km was determined from source time function. When viewed over the entire depthrange, the total duration (τt) is related to Mo by log τt = (0.2642 ± 0.001) log Mo _8.9119 (±.0.194).
