Non-tidal variations of gravity are the residual part of the monitoring of the variations after subtraction from them the lunar-solar gravity variations and the drift of the zero point of the gravimeter. Non-tidal variations are sometimes of complex morphology and structure. The sources of the non-tidal variations are the intracrustal processes and flows of the charged particles in space. The streams of the charged particles can affect the sensor of the gravimeter. The streams of the charged particles can create a powerful magnetic hydrodynamic (MHD) shocks that cause abnormal changes of gravity. It is necessary to consider the non-tidal variations when carrying out high-precision gravimetric measurements.
For the first time, gravity pulsations were detected during the processing of stationary observations at the Geodynamic range of RAS in Bishkek (2014). Then, similar surges were detected in stationary seismic observations in the city of Voronezh, which simultaneously coincided with the gravimetric fluctuations in Bishkek. Later, gravity pulsations were detected at Artie, Perm and Vladivostok stations. Seismic ripples are also found in Southeast Asia. In coastal zones and in the ocean, additional pulsations occur due to atmospheric processes (typhoons, cyclones, etc.). Pulsations of non-tidal variations of gravity and seismic fields are global.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
