Abstract

The establishment of a unified earthquake catalog is a basic requirement for attaining a detailed seismological analysis and an improved seismic hazard assessment. Accordingly, the current research paper aims to present a reliable instrumental unified earthquake catalog for the northern part of Algeria. This unified catalog is compiled using regional empirical relationships derived from converting different magnitude scales to an advanced physical-based moment magnitude scale suggested in the recent literature and denoted by M_wg. The regression methodology used in this study is called the New General Orthogonal Regression approach (N.GOR), which was selected since it is the most trustworthy procedure for scaling the magnitudes to M_wg. To highlight the significance of using the N.GOR, the obtained outcomes of the scaling relations were compared with those issued from the conventional general orthogonal regression (GOR) method, which is deemed to be the most dependable methodology used worldwide for magnitude conversion problems. The unified earthquake catalog was assembled from 1954 to 2022. Reliably converting the original magnitudes into homogenized moment magnitude leads to a complete and consistent unified earthquake catalog. Indeed, the unified moment magnitude catalog presented in this paper could provide reliable data for studying earthquakes distribution and the assessment of seismic hazards in the north of Algeria.

使用稳健回归方法基于高级矩震级尺度的阿尔及利亚北部统一地震目录

摘要

建立统一的地震目录是进行详细地震分析和完善地震危险性评估的基本要求。因此，当前的研究论文旨在为阿尔及利亚北部提供可靠的仪器统一地震目录。这个统一的目录是使用区域经验关系来编制的，这些关系是将不同的震级尺度转换为最近文献中建议的先进的基于物理的矩震级尺度，并用M _wg表示。本研究中使用的回归方法称为新一般正交回归方法 (N.GOR)，选择该方法是因为它是将幅度缩放到M _wg的最值得信赖的程序。为了强调使用 N.GOR 的重要性，将获得的标度关系结果与传统的广义正交回归 (GOR) 方法得出的结果进行了比较，后者被认为是全球范围内用于幅度转换问题的最可靠的方法。统一地震目录是从1954年到2022年编制的。将原始震级可靠地转换为均匀矩震级可以得到完整一致的统一地震目录。事实上，本文提出的统一矩震级目录可以为研究阿尔及利亚北部地震分布和地震危险性评估提供可靠的数据。
