Abstract
Results of synchronous recording magnetic variations and seismic vibrations caused by an earthquake with a magnitude M = 6.7 at a distance of 806 km from the observation site are considered. Measurements are carried out at the VLA observatory. Different patterns of seismic noise generation and their contributions to the magnetic variations recorded by torsion magnetometer are analyzed. As well, the correlation between the seismic and magnetic components is studied. The close correlation between the seismic accelerations of rocks and the magnetic variations is revealed, and its transfer coefficient is estimated. Such correlation in other types of magnetometers is supposed to hinder the measurement of seismomagnetic signals, which will require the seismic noise parameters to be known for different types of magnetometers.
