Development of Automated Moment Tensor Software at the Prototype International Data Center

Abstract

We are porting automatic seismic moment tensor software used by the Berkeley Seismological Laboratory to the Prototype International Data Center (PIDC). This software package utilizes a surface wave spectral amplitude and phase method coupled with a three-component waveform inverse method that is scaleable from teleseismic to regional distances. The objective is to initially develop automatic software for the analysis of Mw5.5 and greater events on a global scale utilizing the International Monitoring System (IMS). For regions of specific interest we will utilize crustal structure calibration information from other DTRA projects to refine capabilities to Mw4.5 and greater. Currently version 0.1 is ported to the PIDC, and several examples of its use are presented. During the course of this project a staged testing program will be employed to refine the software and to provide robust code suitable for operations at the PIDC.
