Abstract

This paper addresses a specific mechanism of atmospheric effects exerted on the crust in ocean offshore areas. If the central region of an atmospheric cyclone or anticyclone lies on the coastline, large horizontal pressure gradients can arise near the Earth's surface: on land, the surface experiences to a full extent the effect of atmospheric pressure disturbances, whereas the latter are largely screened by the water layer in the offshore zone (if it is sufficiently deep). This can result in high stresses contributing to an increase in seismic activity. The stresses and strains are calculated. Resulting estimates agree (at least qualitatively) with experimental data on specific strain patterns in the offshore zone.
