Keywords: horizontal torsion pendulum, coherence, seismic events, influence matrices
Аnnotation: Synchronous recordings of the readings of two torsion pendulums located at a distance of about 3000 km from each other are considered: in the village Mosrentgen (New Moscow) and Novosibirsk. The duration of joint rec-ords is 350 days, from 19.08.2022 to 04.08.2023. The hypothesis is considered that the excitation of oscillations of torsional pendulums precedes strong seismic events, including those whose epicenters are located far from the location of measurements. The presence of two synchronous measurement points makes it possible to get rid of the influence of intense local interference by assessing the coherence spectrum in a sliding time window. The se-quence of times of occurrence of maximum coherences in time windows of 1 hour length is analyzed together with the sequence of seismic events with a magnitude of at least 5 using a parametric model of interacting point processes (influence matrix method). The influence matrix method allows you to give a quantitative measure of the influence of two random time sequences on each other. The assessment of the correlation function between the daily values of the logarithms of seismic energy emissions exceeding a given threshold and the daily average maximum values of the elements of the influence matrix has a strong asymmetry, which gives grounds for quantitative confirmation of the hypothesis that the excitation of torsion pendulums precedes strong earth-quakes with an average delay time of about 20 days.
