Rotation as a new observable in seismology
When the ground shakes, it not only translates (up-down, sideways) but also undergoes rotational motions (yaw, pitch and roll). To fully characterize seismic sources and wave fields, it is necessary to measure both the translational and rotational movements of the ground.
However, until now, this was not possible simply, locally and directly. Long-awaited by seismologists throughout the world, blueSeis’ new sensors truly revolutionize the seismology market by allowing a complete measurement of a seismic wave.
