Impact Assessment of the Effects of Strong Earthquake-Induced Hazards on the Socioeconomic Development Level of Earthquake-Stricken Areas after the 2008 Wenchuan Earthquake

A strong earthquake-induced hazard has obvious long-term and spatial heterogeneity, which will result in continuous social economic losses. Measuring the socioeconomic development level of disaster area is great significance for reconstruction after an earthquake. First, kernel density estimation (KDE) used to analyze effects 10 extremely earthquake-stricken areas Wenchuan earthquake this paper. Second, gravity centers from 2006 2016 are calculated, temporal variation characteristics study analyzed. Finally, relationship between hazards discussed. The results indicate that effect landslide show oscillatory attenuation trend with time 2008 significant differentiation characteristics. move direction “moving northeast first moving southwest later” time, movement closely related industrial structure areas.
