Abstract Ring-laser rotation sensors are contaminated by rotations around horizontal axes (also called tilts) through the vector product between the local normal direction and the vector of the rotation rate composed of Earth’s rotation and local ground rotations. In this study, we investigate theoretically this cross-axis sensitivity and estimate the effects based on magnitude–amplitude relations to be expected for observations of local earthquakes and teleseismic events. We investigate tilt… CONTINUE READING
