The phenomenon of synchronous episodic increase in gravimetric noise at the stations distant by thousands of kilometers from each other is described. The comparison with microseismic noise suggests inertial rather than gravimetric origin of the recorded anomalies. The duration of anomalous enhancement in microvibrations ranges from a few hours to a few days. The nature of synchronous microvibrations involving significant segments of the Earth's lithosphere is unclear; the probable causes are discussed. The conducted analysis has shown that among the key factors responsible for the increase in the microseismic noise in the European part of Russia is the influence of marginal seas, in particular, the storm-generated microseisms. The allowance for this phenomenon is necessary in planning and conducting high-precision gravity surveys and long-term gravity observations. [ABSTRACT FROM AUTHOR] |
