Abstract

Abstract:

A magnitude 6.5 earthquake struck Ludian County, Zhaotong City, Yunnan Province at 16:30 on 3 August 2014, which caused severe damages on residential life and assets. In order to conduct a rapid earthquake impact assessment, we collected data on seismic intensity, topography, land use/land cover, population, residential area distribution, and buildings of the earthquake area and high-resolution remote sensing images. Spatial analysis in GIS and a quantitative evaluation model were employed for the assessment, which focused on the following aspects of the disaster area including natural environmental conditions of the severe impact area, impact on the affected population, buildings, roads and traffic, and other sensitive exposure units, and risk of secondary geological hazards along the Niulan River; and restoring from slope cropland to forest and preventing soil erosion. Based on the assessment results, this article provides the some suggestions for the earthquake relief effort, geological hazard prevention, and post-disaster reconstruction and ecological recovery of the Ludian seismic area.

Key words: Ludian Earthquake, disaster impact, countermeasure and suggestion, Zhaotong of Yunnan
