Seismic Activity and Seismic Cone Tectonics on the West Coast of the United States
Abstract: In the west coast of the United States, there are frequent strong earthquakes and volcanic activities in the crust, high accuracy of the earthquake catalogue, so it is the best choice to study prediction of strong earthquakes and volcanoes, and there are two different types of seismic cone tectonics, volcanic type and intracrustal strong seismicity type, so it becomes the epitome of global earthquake prediction research, rarer. In this paper, according to the data of ANSS earthquake catalogue in the United States, using the Seismo-Geothermic Theory and its methods, the images were processed such as the planar distribution images and the three-dimensional images of the general earthquakes, subcrustal earthquakes, intracrustal strong earthquakes and volcanic eruption and the sequence diagrams of subcrustal earthquakes in the study area, as well as theory explanation of their relations with the San Andreas Fault. According to this idea, the volcanic origin and precursory information of U01 mini seismic cone tectonic were firstly studied, then the causes of intracrustal strong seismicity of U02 mini seismic cone tectonic and their migration rules were studied. The precursory information of M7.1 earthquake on July 6, 2019, was analyzed and summarized in U02 mini seismic cone tectonic, and a basic method for handling similar events in the future was given. In this paper, it thinks strong earthquake and volcanic disaster are from deep mantle heat energy, rather than the result of the independence movement of surface structure. Therefore, it finds the most natural energy of causes of seismicity and volcanic activity and opens a new direction for the prediction research of earthquakes and volcanoes.
