Title

SIMULATING EARTHQUAKE LOCATION ERRORS AND ITS APPLICATION TO THE TEHRAN SEISMIC NETWORK

Pages

  71-80

Abstract

 Earthquake location is an inverse problem that usually involves inverting the imperfect ARRIVAL TIME readings for the earthquake parameters. When the forward model (a method for computing ARRIVAL TIMEs) is derived then the final solution will be obtained based on a misfit criterion that minimizes the discrepancy between the calculated and measured data. The event location uncertainty is caused by: the errors in the ARRIVAL TIMEs of the picked phases, misidentification of seismic phases, and the errors in the travel-time model used in the location process. The event mislocation induced by these sources is affected by the number and configuration of the stations that record the events. In this paper the EXPECTED ERRORs for the Tehran digital seismic network has been simulated, considering two different velocity models. It has been found that the EXPECTED ERROR along the longitude of the network is less than the EXPECTED ERROR along its latitude. Meanwhile epicentral EXPECTED ERROR seems to be high. So it is proposed to consider this method results not only for the Tehran network but also for other present and future seismic networks.
