| 英文摘要 | As a part of ground motion, the rotational component provides important additional constrains for signal processing, interior structure and source mechanism studies. However, the lack of high precision instrument limits related applications. Recently, the new developed fiber-optic gyroscope (FOG) is used a portable and inexpensive rotational seismometer. Wuhan National Geodetic Observatory deployed two FOGs and one three-components broadband seismometer on same base plate to continuously record seismic signals. This Love wave excited by the M(s)6. 4 Yunnan Yangbi earthquake clear emerges on the records of this multiple-component seismometer. The apparent velocity and incident angle are obtained from comparison between the vertical rotation rate and the tangential acceleration records. The apparent velocities show clear dispersive and are in reasonable scale. The incident angle of the Love wave is close to the great-circle and the incident angle of the coda wave is more scattered. This study suggests that the collocated FOGs and seismometer can provides useful information for studies on interior structure and other aspects of seismology. |
