Abstract
A possible influence of tropical cyclones on seismic activity in the cyclonic zone of the northwestern Pacific is considered. There is no direct and sufficiently reliable method for calculating the degree of impact of tropical cyclones on the Earth's crust. Therefore, a sort of inverse problem is solved in the investigation: a possible qualitative influence of tropical cyclones on seismic activity is estimated from its intra-annual dynamics. It is established that for territories of the cyclonic zone, the intra-annual dynamics of cyclonic and seismic activities are similar. Low monthly mean values of the cyclonic and seismic energies are attained in July-October, whereas in the continental territories under consideration (Central Asia), the seismic activity is higher in January-March. The results obtained suggest that cyclones can affect the seismic regime in the cyclonic zone of the northwestern Pacific.
