Abstract:Based on the earth geo-resistivity observation data in Shaanxi Province from 2011 to 2018, we analyzed the main factors that affect these observations, including the failure of the observation system, the interference of the natural environment, and the interference of the site environment. In this paper, we calculated the interference amplitude of the observed data, and obtained the time scale of the interference. We then analyzed the form of each type of interference and the morphological characteristics of the observation data curve. Based on this, we proposed methods and made recommendations for interference suppression, and analyzed the physical mechanism of observed data change under the influence of interference factors. In addition, we clarified the basic workflow of data application in earthquake prediction, declared the importance of identifying all types of interference factors accurately, sought ways to solve interference problems, and explored new methods to process interference data.
