Abstract
AbstractEarthquake is one of the most serious natural disasters, which has caused huge casualties and economic losses to human society every year. It is very necessary and urgent to construct a platform to prevent and mitigate earthquake disaster. Compared with the traditional seismic data management methods that always only use a single isolated information technology, seismic spatial information grid(SSIG), which is a thematic spatial information grid with applications of geo-informatics in earthquake disaster management, has integrated many kinds of spatial information technology. In this paper, SSIG has been introduced into earthquake disaster management. It describes the construction, data acquisition, storage and application of SSIG. The proposed system was exemplified in Yushu earthquake in Qinghai province of China. The case applications show that the SSIG can effectively manage and analyze massive seismic data. As the system has run very stably, it can be recommended to a national level of China.Keywordsspatial information gridearthquakedisaster and risk managementgeo-informaticsseismic thematic grid
