Estimations of Sensor Misorientation for Broadband Seismic Stations in and around Africa

<p>To ensure the accuracy of future rotation-based seismological studies using data recorded by broadband seismic stations in Africa and environs, we investigate the sensor orientation of 1075 stations belonging to 41 seismic networks deployed in and around the African continent in the past three decades. We applied three independent waveform-based orientation estimation methods that involve the measurement of P-wave particle motion based on the principal component analysis, minimizing the P-wave energy on the transverse component of motion, and measuring intermediate-period Rayleigh-wave arrival angles from teleseismic earthquakes. This dataset is the compilation of the entire result of this study.</p>
