First deep underground observation of rotational signals from an earthquake at teleseismic distance using a large ring laser gyroscope

[摘要] Recent advances in large ring laser gyroscopes (RLG) technologies opened the possibility to observe rotations of the ground with sensitivities up to 10−11 rad/sec over the frequency band of seismological interest (0.01-1Hz), thus opening the way to a new
