[Abstract]:After the earthquake occurs, before the destructive seismic wave arrives, monitoring the seismic wave signal through the station, estimating the seismic parameter, and issuing the earthquake warning information in time are the effective means to reduce the earthquake loss and reduce the casualties. In this paper, the main attenuation laws of ground motion intensity (intensity) at home and abroad are summarized, and the estimation module of ground motion intensity (intensity) based on ground motion attenuation model is established. This paper designs the structure of earthquake warning information publishing system and database structure, studies the realization technology of pseudo-multithreading, temporal GIS, map offset correction and so on, realizes the multi-platform and quasi-real-time information release function of earthquake warning information publishing system. The main contents of this paper can be summarized as follows: (1) on the basis of summarizing the main attenuation laws of ground motion intensity (intensity) at home and abroad, a seismic intensity (intensity) estimation module based on ground motion attenuation model is established. The earthquake source-bedrock-site surface seismic intensity (intensity) estimation is realized. After the input of three elements of earthquake, combined with V data layer, fault data and so on, the module can quickly get the estimated earthquake intensity (intensity) in the early warning service area. (2) according to the requirement of the earthquake warning demonstration system, the structure of the system and the database structure are designed, and the function modules of the system and the interface between them are determined. Based on the Java language, the PC platform, mobile platform and website platform of the earthquake warning information publishing system are implemented, which can estimate the time of the earthquake occurrence, the location of the epicenter, the magnitude of the earthquake, and the destructive seismic wave in time. The earthquake warning information such as earthquake intensity (intensity) is sent to the earthquake warning service. (3) some key technologies are studied in the implementation of earthquake warning information release system. According to the characteristics of single thread of browser, pseudo-multithreading technology is studied, and the monitoring of early warning information on browser is realized at the same time. The propagation process of seismic wave is simulated. According to the function of earthquake warning and reproducing, the temporal GIS technology is studied, and based on the ArcGIS platform, the recurrence of earthquake process or early warning process is realized. Aiming at the coordinate migration of Baidu map, this paper studies the correction technology of electronic coordinate migration map, and realizes the correct display of seismic information on Baidu map.
