Impact of France Nuclear Tests on typhoons and Earthquakes in November 1990
Abstract
The paper investigates the relationship between the development of typhoons and strong earthquakes after the France nuclear tests (NT) in November 1990. It is shown that after the NT acoustic impact on the tropical disturbance of the Pacific Ocean cloud structures self-organized into a system of three interacting category 5 typhoons. The dependence of the earthquakes M> 4.6 and the intensity of these typhoons as well as Typhoon Mike which passed earlier through the Philippine Islands are considered. Areas were found where the impact of typhoons led to earthquakes M> 5.4 of small lithospheric plates

Introduction
Three mechanisms of interaction between tropical cyclones (TC) and strong earthquakes are usually considered. The first one is that vertical displacements of the Earth's surface in the zones of action of a cyclone and anticyclone can cause a stress release in seismically active regions, as shown by the example of Kamchatka in [1].
The second one is associated with oscillations of long waves excited by TC in the coastal zone. This mechanism has been studied using special seismic sensors at ~ 2800 US stations for more than 10 years [2].
The third one is associated with the lithospheric mechanism of the transfer of the moment of forces from the rarefaction area under the TC when it is located near the edge of the large lithospheric plate adjacent to the small one. This mechanism was considered in the analysis of small lithospheric plate earthquakes with magnitude M> 4.5 without foreshocks of [3].
Conclusion
1. Almost all lithospheric earthquakes in the regions adjacent to the Philippine Plate can be explained in terms of the impact of tropical cyclones in November 90.
2. France Nuclear Tests acoustic impact on tropical disturbance areas led to their self-organization to the intensity of super typhoons in November 90.
3. Preliminary analysis showed that the TC impact on the Pacific Plate in November 90 was transferred to the area of MidAmerican Trench and Peru-Chile Trench. A detailed analysis of these events will be presented.
