The Kakioka Magnetic Observatory conducts precise observation of global geomagnetic phenomena at Kakioka, Memambetsu, Kanoya and Chichijima. Services include daily reporting and ad-hoc provision of information on significant phenomena such as magnetic storms for use in warnings for radio communication. Research is also conducted to develop geomagnetic observation techniques, clarify related phenomena and support volcanic activity evaluation based on electromagnetic observation. Observation results are promptly provided in technical reports and elsewhere for reference by various organizations. Data from Kakioka are used to maintain Japan's standard magnetometers, and verification services are provided for magnetic monitoring instruments such as compasses on ships and aircraft.
Magnetic observation is carried out at Kakioka, Memambetsu, Kanoya and Chichijima as geomagnetic reference stations in central, northern, western and southern Japan, respectively, to cover the whole country. All observation data are collected at Kakioka for efficient processing and storage. Kakioka, Memambetsu and Kanoya are designated among approximately 120 Intermagnet observatories worldwide, providing magnetic observation data in quasi-real time. Observation systems on test fields for volcanomagnetic signal detection are also operated at Mt. Meakandake, Mt. Kusatsu-Shirane and Izu-Oshima, with data serving as supplementary information for volcanic activity assessment.
