Embodiment

[0103] Such as figure 1 Shown, a kind of seismic intensity rapid correction and mapping method of the present invention comprises the following steps:

[0104] S1: Obtain the three elements of post-earthquake earthquake, multi-source disaster data, discrete intensity point data and fault zone information, and obtain aftershock information along with the development of aftershocks;

[0105] S2: Generate a preliminary assessment seismic intensity circle according to the three earthquake elements, and generate a preliminary assessment seismic intensity thematic map according to the mapping template according to the preliminary assessment seismic intensity circle;

[0106] S3: Fuse the multi-source disaster data as the basis for the correction of the preliminary assessment seismic intensity circle to generate a preliminary revised seismic intensity circle, and generate a preliminary revised seismic intensity circle according to the preliminary revised seismic intensity circle acco...

Abstract

The invention discloses a seismic intensity rapid correction and drawing method. The method comprises the following steps: generating an initially evaluated seismic intensity thematic map; generatinga primarily corrected seismic intensity thematic map; obtaining the range of the meizoseismal region and the long-axis trend of the intensity circle; establishing an envelope line; obtaining a highestintensity circle; obtaining a seismic intensity dynamic correction result; generating a dynamically corrected seismic intensity thematic map; and generating a final seismic intensity thematic map. According to the invention, automatic generation of the seismic intensity thematic map is realized; multi-source disaster data is fully applied; preliminary correction is performed on the intensity circle through a data fusion technology; the influence of aftershocks and the like on the intensity circle is fully considered, and meanwhile, the intensity circle is further dynamically corrected throughthe self-adaptive technology; the automation degree is very high, manpower and material resources can be greatly reduced while the reliability of the intensity circle is improved, and the efficiencyis very high; and the earthquake intensity thematic map can be rapidly generated after an earthquake happens.

Description

technical field [0001] The invention relates to seismic digitization technology, in particular to a method and system for rapid correction of seismic intensity and mapping. Background technique [0002] Seismic intensity refers to the intensity of the ground vibration caused by an earthquake and its impact, and it is a description of the severity of the disaster in the earthquake-stricken area. The seismic intensity map refers to the spatial distribution of the intensity after an earthquake event. It is used to intuitively reflect the degree of disaster in different areas of the disaster area and the extent of damage caused by the earthquake. It is the most intuitive way for government departments to understand the scale and scope of earthquake damage immediately after the earthquake. . It can provide a scientific basis for earthquake disaster relief work such as assessing earthquake disaster losses, determining earthquake emergency rescue plans, deploying rescue forces, dr...
