Sugeno fuzzy inference algorithm and its application in epicentral intensity prediction

•We propose the epicentral intensity prediction model.•We do statistical analysis aimed at the historical data.•We obtain the estimations of parameters for our proposed model.•We do comparison with Du’s fitting model.

In this paper, the epicentral intensity prediction model based on Sugeno fuzzy inference system has been proposed where the earthquake magnitude and the depth of hypocenter are input and the epicentral intensity is output. The parameters of the proposed model are estimated by statistical analysis based on the historical data for Sichuan earthquake in the last decades. Finally, by comparison with the existing fitting model, the proposed model has better efficiency and higher accuracy.
