Abstract
This paper is focused on analysis of comprehensive experimental research data on the infragravitational range of periods (from 20 s to 10–12 min) obtained by synchronous measurements of fluctuations in deformations of the Earth’s crust and atmospheric and hydrospheric pressure variations. It is established that the identified variations in the period range of 1–4 min are rarely observed in records of a laser nanobarograph and laser instrument for measuring hydrospheric pressure variations (laser hydrophone), while they are frequently observed in records of laser strainmeters at a variation period of 3–4 min. Oscillation excitation in the period ranges of 7–13 min, especially in the period ranges of 8–12 min, is largely related to atmospheric processes in the corresponding periods.
