**The ENIGMA network shares data from eight instruments in four regions, so gravity changes tied to earthquakes and Earth's interior can be analysed jointly rather than from a single station.**

South Korea's National Institute for Mathematical Sciences (NIMS) and the Korea Institute of Science and Technology Information (KISTI) are holding the 2026 ENIGMA International Cooperation Conference on Astrophysics and Geophysics at the Hidden Cliff Hotel & Nature on Jeju from the 8th to the 12th, biz.heraldcorp.com reported on the 11th. About 50 experts from 14 countries are attending to discuss expanding the precision gravity observation network and activating joint international research [1]. The network connects eight ultra-precise gravity instruments in Korea, China, Japan and Taiwan [1].

## ENIGMA network and superconducting gravimeters

ENIGMA is an East Asian gravity measurement network launched in 2024 under the leadership of NIMS. Its goal is to share and jointly analyse observation data from eight superconducting gravimeters installed in four regions [1]. A superconducting gravimeter measures minute changes in Earth's gravity and is used to study geophysical phenomena such as mass movement inside the Earth and earthquakes [1].

According to the report, analysing gravity data measured at several locations together allows a more accurate understanding of wide-area gravity changes and geophysical phenomena that are difficult to grasp from a single observatory [1].

The conference shares results from the YeMiGO low-gravity observatory, operated jointly by NIMS and the University of Calgary in Canada, along with the state of gravity observation in each East Asian country [1]. The main topics are earthquake observation and disaster research, development of next-generation gravity sensors, and analysis of gravity and seismic data [1]. NIMS researcher Son Jae-ju presented the YeMiGO observation experience and proposed international cooperation to improve data quality through long-term stable observation and environmental noise analysis [1].

## Data hub and mathematics

NIMS and KISTI are also strengthening the data infrastructure for joint use of the observations. Data from each country is to be managed centrally around the ENIGMA Data Hub, run by KISTI's Large-scale Data Hub Center (GSDC), and the environment in which researchers analyse the data together is to be improved [1]. The stated aim is to raise the usability of gravity data now scattered across countries and to expand joint research in geophysics and astrophysics [1].

GSDC head Jo Gyu-jin said the hub will support data use between institutions and strengthen support for joint research [1].

The event also discussed ways to spread mathematical culture among the general public by showing how gravity observation relates to mathematics. NIMS researcher Yu Myeong-san presented results of precision gravity observation and mathematical modelling, and a way to convey to the public how complex natural phenomena are understood through mathematics [1]. NIMS director Choi Yun-seong said he hopes the conference will strengthen cooperation among research institutions at home and abroad and lead to new results in geophysics and fundamental physics [1].
