摘要

本文基于中国电磁监测试验卫星全球地磁场模型 (CGGM-2) 2018—2025 年高精度地磁观测数据, 融合地震地热说的核心理论, 结合 1963—2026. 3. 12 全球 M≥4. 0 地震目录 (563956条) , 系统解析南大西洋异常区 (SAA) 地磁异常与地震柱构造 (SCT) 、壳下地震、壳内强震的耦合机制。研究表明, CGGM-2 模型揭示的 SAA 区域的双极小值地磁演化特征, 与欧洲航天局 (ESA) Swarm卫星2014—2025年的磁异常图像一致并相互验证; 二者与地震地热说阐释的地震柱构造热动力学过程高度吻合。地磁场的空间异常分布和时间非线性变化, 是深部地热活动驱动地震柱构造演化的直接地球物理响应, 地磁减弱速率可作为地热扰动强度的重要指标。结果证实: 地热活动是调控地球深部动力学、地磁场演化及壳内强震与火山活动的核心动力。SAA 区域地磁-地震耦合关系, 为地震地热说提供了高精度的地磁学实证, 也为壳内强震与火山活动的预测开拓了新的路径。

Abstract

Based on high-precision geomagnetic observations from the second-generation CSES Global Geomagnetic Model (CGGM-2) from 2018 to 2025 integrated with the core theory of Seismo-Geothermics and the global earthquake catalog of M≥4. 0 from 1963 to March 12, 2026 (563, 956 events) , this paper systematically analyzes the coupling mechanism between geomagnetic anomalies in the South Atlantic Anomaly region (SAA) and Seismic Cone Tectonics (SCT) , subcrustal earthquakes, as well as intracrustal strong earthquakes. Results show that the evolutionary characteristics of the double geomagnetic minima in SAA revealed by CGGM-2 are consistent with and verified by the magnetic anomaly maps of SAA from 2014 to 2025 observed by ESA Swarm satellites. Both of them are highly consistent with the thermokinetic processes of Seismic Cone Tectonics proposed by Seismo-Geothermics. The spatial anomalous distribution and temporal nonlinear variation of the geomagnetic field represent direct geophysical responses to the evolution of Seismic Cone Tectonics driven by deep geothermal activities. The geomagnetic weakening rate can serve as an important geophysical indicator for the intensity of deep geothermal disturbances. It is confirmed that geothermal activity is the core driving force governing Earth’s deep geodynamic processes, geomagnetic field evolution, and intracrustal strong earthquakes and volcanic activities. The geomagnetic-seismic coupling in SAA provides high-precision geomagnetic evidence for Seismo-Geothermics and opens a new pathway for the prediction of intracrustal strong earthquakes and volcanic activities.
