Abstract: Taking the website of China Earthquake Networks Center as an example, this paper collects traffic statistics for one year. In terms of website traffic trends, user source channels, access paths, and visitor conditions, we systematically analyze user accessing behaviors. The conclusions have been applied to its next stage website revision. The mode, which takes the accurate analysis of user behavior based on big data as decision basis for the website revision and upgrading continuously, provides new ideas of operation and maintenance for other seismic industry websites.
