Orienting Ocean-Bottom Seismometers from P-wave and Rayleigh wave polarisations

Abstract:

We present two independent, automated methods for estimating the absolute horizontal misorientation of seismic sensors from their recorded data. We apply both methods to 44 free-fall ocean-bottom seismometers (OBS) of the RHUM-RUM experiment (http://www.rhum-rum.net/). The techniques measure the three-dimensional directions of particle motion of (1) P-waves and (2) Rayleigh waves of earthquake recordings. For P-waves, we used a principal component analysis to determine the directions of parti...
