SEISAN software application for developing an automated seismological data analysis workstation

The key stages of automation of routine earthquake data processing are described. The software, technologies, and equipment are specified. The method for determining earthquake source parameters is considered in details. The experience in the seismological data interpretation taking recent velocity profiles of the region into account is demonstrated and the determination accuracy is justified. The information about the configuration of the local network of seismic stations and the velocity structure of the earth’s crust in the north of Sakhalin Island is presented.
