Abstract
The distinctive annual periodicity in the week earthquake activity in the Garm region and its possible origin were described in the author’s previous papers. In this paper, an attempt is made to relate the annual earthquake periodicity to such a phenomenon as hydroseismicity. Within the framework of the study, seasonal variations in seismicity, snow height, and the water level of the Surkhob River are compared. As a result, good coincidence of the form of spring changes in snow height and seismicity has been revealed. It is important that according to averaged data, seismicity follows changes in snow height with some lag. However, a few cases in certain years have been found when the number of earthquakes began decreasing simultaneously or even a little before snow melt. It was also discovered that annual changes in the river water level and seismicity occur in opposite phase. Possible approaches to interpreting the results are discussed.
