Abstract

A multifractal methodology was utilized to analyze a set of seismic sequences distributed along the Pacific Ring of Fire, sourced from the National Earthquake Information Center (NEIC) catalog. The analysis employed the Multifractal Detrended Moving Average (MFDMA) analysis method to characterize the presence of intrinsic multifractality using different multifractal indicators. The findings of this study can be summarized as follows: our statistical tests confidently assert that only the Kuriles, Peru, and Solomon Islands zones demonstrate an absence of intrinsic multifractality; tests were also applied using the exponent , but they were inconclusive. We believe these results contribute to an enhanced understanding of the multifractal characteristics of seismic activity and their implications for earthquake dynamics.
分析沿太平洋火环分布的地震序列的内在多分形性质
利用多分形方法分析了一组沿太平洋火环分布的地震序列,这些序列来自国家地震信息中心(NEIC)的目录。分析采用了多分形去趋势移动平均(MFDMA)分析方法,利用不同的多分形指标来描述内在多分形的存在。这项研究的结果可归纳如下:我们的统计检验有把握地断定,只有千岛群岛、秘鲁和所罗门群岛区不存在内在多分形;我们还使用指数Ⅴ进行了检验,但没有得出结论。我们相信这些结果有助于加深对地震活动多分形特征及其对地震动力学影响的理解。

期刊介绍: General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
