Research using seismic waves for orientation of the Ocean - Bottom Seismographs

Abstract

Orientation of the Ocean-Bottom Seismograph (OBS) devices is an important task that must complete before using these data. While the OBS direction is determined correctly, we can correct the rotation angle of the coordinate system so that we obtain the maximum amplitude seismic signals for different seismic waves. In this article, we present the method using seismic waves to determine the direction of the OBS. The results obtained from 11 OBSs in the East Sea show that these stations have misdirected from different angles. This method has advantage with high reliability. Specially, we can widely apply for the OBS devices in other oceans.
