ENIGMA: East-Asian Network Initiative for Gravity Measurement Alliance

We announce the establishment of ENIGMA (East-Asian Network Initiative for Gravity Measurement Alliance), a high-precision observational network of superconducting gravimeters spanning South Korea, Japan, Taiwan, and mainland China. By strategically deploying a parallel observation belt along the major seismogenic zones—including the Japan Trench, Ryukyu Trench, and Nankai Trough—ENIGMA aims to monitor subtle micro-gravity fluctuations associated with the circum-Pacific "Ring of Fire." This spatial configuration enables the systematic analysis of seismic events across diverse magnitudes, focal mechanisms, and depths.

Central to this initiative is the development of a dedicated data hub designed to standardize data formats, facilitate seamless sharing, and provide high-performance computing resources for collaborative research. Beyond traditional geophysics, the network’s exceptional sensitivity offers a novel frontier for fundamental physics, such as searching for dark matter candidates within the Earth’s interior. This presentation outlines the scientific roadmap and various high-impact use cases enabled by the integration of GWR Instruments’ superconducting gravimeters and the ENIGMA data infrastructure.
