Abstract: The article explores the boundaries and fault systems of the Caroline Plate utilizing magnetic anomaly data. The research is aimed at comprehensively understanding the tectonic dynamics and geological features of this region, particularly the mutual movements between the Pacific Plate, the Philippine Sea Plate, and the Caroline Plate itself. The study focuses on employing geophysical methods with geological constraints to study plate boundaries by processing geomagnetic anomalies, including the reduction-to-pole technique fit for low-latitude regions. Key findings of the article include the identification of fault zones within the Caroline Plate and their characteristics, such as the sinistral strike-slip movement and associated tectonic features like the Sorol Trough and Ayu Trough, which signify a counterclockwise plate rotation. The research also discusses the coupling between magmatic activity and plate structures, as faults influence the flow of magma and the formation of large igneous provinces. The exploration into the Eauripik Rise further reveals insights into the magmatic sources and age correlations with plate-spreading events. However, uncertainties remain regarding the southward migration of magma associated with the Eauripik Rise. Finally, the study’s conclusions emphasize the role of fault zones as channels for magma migration and the Caroline Plate’s dynamic geological history.
