Abstract

Abstract—Deviations of the vertical crustal velocities measured by a broadband seismic station from the Earth’s tidal velocities predicted by theory are calculated. The deviations are compared with weather data at station site. It is shown that during the intervals of simultaneous occurrences of low atmospheric pressure and rainfalls, strain anomalies reaching half of the diurnal variations of tidal velocities arise. The anomalies appear a few hours after the time of the minimum pressure and heavy rains and last a few days.
