The study of tilts and strains at the Protvino geophysical station

The instrumentation at the Protvino station was substantially upgraded duri ng the period from 1997 to 1999. As a result, the amount of recorded inform ation increased by a few times, and the resolution and actual accuracy of m easurements improved. The paper presents the performance capabilities of th e instrumentation (tiltmeters, strainmeters, barograph, well water-level ga uge, and thermograph) and the digital system of geophysical data acquisitio n. Information is recorded in a form suitable for on-line control and subse quent analysis is conducted with the help of special software. Some results of processing the recorded geophysical data, in particular, background noi se and its dependence on the atmospheric conditions, are analyzed. The micr odeformations of the Earth's surface are shown to depend on synoptic phenom ena.
