Gravity and seismic noise pulsations on the eurasian continent

Abstract

For the First time, gravity pulsations were detected during processing of stationary observations at the Geodynamic range of RAS in Bishkek (2014). Later similar pulsations were revealed in seismic stationary observations in Voronezh (Geophysical service of the Russian Federation, 2015), which coincided with gravimetric pulsations in Bishkek. The mentioned synchronicity circumstance is now analyzed for other regions of Russia where data on seismic and gravimetric observations are available. In particular, the examples of synchronous variations of the vertical component of seismic and gravitational fields at the stations of Arti (Russia, Yekaterinburg), Voronezh (Russia), M. Schultz (Russia, Primorye) and Bishkek (Kyrgyzstan) are considered. Ripples of non-tidal variations of gravity and seismic field in these points exist synchronously. The frequency characteristics are also identical. Most likely, the ripples are due to meteor showers. The greatest density of meteor showers is confined to the winter months . Pulsations have periods of oscillation in the range of 0–20 min.
