Time–space Distribution Characteristics of the Circum-Pacific Seismic Belt Based on Multifractal Analysis

A complete scientific system of earthquake prediction has yet to be developed, and most studies on the time–space sequence of seismic activity analysis are based on existing seismic models. By applying fractal theory with the two aspects of magnitude and intensity, a new dimension is added. In this study, we applied multifractal theory to analyse data of the Circum-Pacific seismic belt, which contains multifractal spectrums such as the relation, relation, and relation. The results suggest that earthquakes in the area which we studied contain multifractal features. The study also shows that the time–space propagation characteristics of the earthquakes are affected by the internal geological structures of the region and the adjacent area.
