Abstract

The invention discloses a method and a system for determining an earthquake sensitive range. The method comprises the following steps: dividing a target area into a plurality of space grids; segmenting the topographic data of the target area by using space grid data to obtain a plurality of pieces of topographic partition data; based on a digital elevation model, carrying out statistics on an average elevation value of each piece of terrain partition data; determining an initial earthquake sensitive range; and correcting the initial seismic sensitive range through the average elevation value. According to the method, the scientificity and the accuracy of determining the earthquake sensitive range can be improved.

Description

technical field [0001] The invention relates to the field of earthquake disaster determination, in particular to a method and system for determining an earthquake sensing range. Background technique [0002] As we all know, earthquake disaster is a kind of extremely destructive natural disaster, often causing a lot of property loss and casualties. After the earthquake, quickly assessing the disaster situation in the shortest time and obtaining the disaster assessment results are an important basis for the government's decision-making and deployment of earthquake relief, and it is the primary task of earthquake emergency work. The traditional method of determining the sensing range of earthquakes is to use the classical attenuation formula, which does not consider the influence of terrain in different regions, and the determination results have great uncertainty. In recent years, with the development of information technology, some scholars have proposed methods for determin...
