The Implementation Of Shanghai Earthquake Emergency Integrated Database And Platform

Shanghai, is China’s economic center and was listed as the national key region ofearthquake monitoring and Prevention. Shanghai earthquake emergency rescue workis of great significance. The earthquake has the characteristics of sudden, forecastinguncertainty and destructive. The earthquake emergency is a comprehensive process ofan interdisciplinary collaboration, multi service, and multi sector. Earthquakeemergency rescue is paid attention to by the countries suffering from natural disasters.Like the United States, Australia, Japan, India and other countries. They haveestablished rich information, highly integrated platform for the emergency disposal, inorder to improve the earthquake response speed and the accuracy of the dynamicevaluation and auxiliary decision-making.During the "tenth five-year plan", a set of earthquake emergency commandsystem have been established. The system run for several years, in the "Wenchuan","Yushu","Ya’an" earthquakes, showing the abuse of "isolated type" system: A singledata source makes information output not abundant enough. Standardized assessmentmodel localization is not high so that the regional earthquake disaster assessmentresult is inaccurate. Other disadvantages like slow response, lack of macro disastermonitoring and so on. So it is needed to integrate multi-source heterogeneous data ofShanghai earthquake and establish Shanghai comprehensive earthquake emergencydatabase. That is the foundation of Shanghai emergency disposal integrated platform,which with characteristics of information sharing, localization, rapid response, macro disaster real-time tracking as well as unified dispatching rescue site.Paper adopts the integration of heterogeneous data integration and the earthquakeemergency disposal to platform design research methods. The effective integration ofseismological data is the basis of emergency disposal system of comprehensiveservice. Through the analysis of the characteristics classification, function andheterogeneity of seismic data, they can be divided into two categories: real timeobservation data and static background, historical data, and then be integratedrespectively. For large quantities, observations of time-sensitive data, with the methodof homogeneous data migration and based on the middleware for heterogeneous dataintegration, real-time observation of the core database is established. For multiplesources, a wide variety of static background, historical data, the integrated method isbased on data warehouse after analyzed some researchers’ work about historicalobservation data integration in the field of earthquake monitoring and prediction.According to the demand characteristics of earthquake emergency data whenearthquake happens, join for data exchange between a data pool, and build Shanghaiearthquake comprehensive database in the end.By comparing the national earthquake emergency command system and Fujianearthquake rapid assessment system， analyzed the requirements of ShanghaiEarthquakes integration platform. The Shanghai earthquake emergency disposal ofintegration platform is based on the Shanghai earthquake comprehensive database.Several of comprehensive business information can be displayed. According to thepopulation-building relational data, created disaster evaluation model accord withthe actual situation of Shanghai area to improve disaster assessment accuracy. In theplatform, emergency products generate speed increased to10seconds. Using ofhigh-definition cameras and wireless network technology, macro disaster monitoring,rescue site and command center convenient resource scheduling are effectivelyestablished.The proposed method of multi-source heterogeneous data integration ofearthquake science and applied in the emergency disposal of the Shanghai earthquake,is the first case in earthquake industry of China. At present, the paper successfully applied in municipal science and technology commission of Shanghai earthquakeemergency disposal integration platform construction project. It has been applied toShanghai Earthquake Administration business department, and for all levels ofgovernment service. Mainly used in seismic information display and emergency drills.In several peripheral earthquake emergency rescues it achieved good results.Operation shows that the platform can effectively improve the computing speed andaccuracy of earthquake emergency disposal, has a good effect in practical application.
