Method and system for advanced early warning and forecasting of earthquake disasters

Abstract

The invention discloses a method and a system for advanced early warning and forecasting of earthquake disasters. The method comprises the following steps of: arranging a monitoring cable and a mechanical sensor in an earthquake-zone fault to detect the earthquake-zone fault surface shearing force, wherein the mechanical sensor is connected with the monitoring cable to sense the tension of the monitoring cable; calculating the earthquake-zone fault surface shearing force based on the following formula, wherein P is the earthquake-zone fault surface shearing force, M is the tension of the monitoring cable, alpha is the strengthening angle for the tension of the monitoring cable, theta is the included angle between the earthquake-zone fault surface and the horizontal plane, phi is the weighted average of all soil-layer internal friction angles in a shattered fault zone, and C is the weighted average of all soil-layer internal cohesions in the shattered fault zone; and sending out earthquake early warning and forecasting when the earthquake-zone fault surface shearing force is larger than an early warning value. The invention can send out earthquake early warning and forecasting signals before and after the movement of the earthquake fault, thereby actually realizing advanced and real-time early warning and forecasting of earthquake disasters.

Description

technical field The invention relates to a natural disaster forecasting method and system, in particular to an earthquake disaster early warning and forecasting method and system. Background technique Earthquake is a natural phenomenon that brings huge disasters. Its most prominent features are suddenness and huge destructive power. If the time, location and intensity of future major earthquakes can be accurately predicted, the disasters caused by earthquakes can undoubtedly be greatly reduced. Since the 1960s, earthquake prediction, especially mid- and long-term prediction, has made some meaningful progress. In terms of long-term prediction, the most prominent progress is the confirmation of the large earthquake gap at the plate boundary, however, there is little progress in short-term and impending earthquake prediction. From the observation of some microscopic precursors before the earthquake, such as crustal deformation, groundwater level changes, geomagnetic and geoel...
