Abstract

During the period from 2004 to 2008, we established the broadband seismic network consisting of 8 stations in Far Eastern Russia, in order to detect seismic waves passing through the stagnant slab distributed in depth range from 660 to 900 km and to clarify the feature of the stagnant slab beneath Far Eastern Russia. At each seismic station, STS-2 broadband seismometer and a short period seismometer are installed using 24 bits analog/digital converter with 100Hz sampling and the records are stored continuously on a nonvolatile memory card. In this paper, we report the seismic network in detail.
