Abstract:: The relative relationship between monitoring video and seismic intensity is established. The empirical matrix is used to qualitatively analyze the seismic intensity based on the massive monitoring data. And we extract seismic damage and intensity information in video,and establish a method of strong ground motion analysis based on the change of the video primitive. The peak acceleration value of the ground motion can be calculated and packaged into software and thus the earthquake can be extracted in the quake zone of video monitoring. And this result can be used as a reference of disaster field investigation and evaluation of earthquake intensity distribution. Earthquake Administration of Zhejiang Province launched fast determination method of seismic intensity distribution based on massive video,and in 2014,it preliminary application achieved good results in the Wencheng-Taishun M_S4.2 earthquake emergency.
