The geomagnetic fields in the atmosphere can be affected by phenomena in the Earth, so that changes of geomagnetic intensity might be used as an indicator of earthquake occurrences. Variations of geomagnetic data have been analyzed in association with the Tohoku Earthquake on March 11th 2011. The Geomagnetic data have been derived from Memambetsu (MMB), Kakioka (KAK) and Kanoya (KNY) Observatories, which are INTERMAGNET observatories. The analysis was performed by calculating the power spectral density ...

The previous research used geomagnetic method on 36 sample located in Mataram with radius 5x5
kms2, have resulted isogram map that clearly indicated extreme magnetic dipole of 70.383,4nT
(03535 '05, 34 " LS ll6`§07?22,8"BT at Karang Kemong) and -26_395,5m" (0ti*'37't5,2" LS
l l 6° 05 'l L6 "BT at Asrama Haji, Jalan Lingkar Selatan). This value has been corrected with IGRF of
45.000nT1 This paper will report the results of advance research to identify the sources of the extreme
geomagnetic ...

The geomagnetic field is a kind of natural potential field in the Earth. A three-year research program for exploration of this field has been conducted in the Lombok Island-Indonesia, where extreme geomagnetic anomalies with two very strong dipolar structures exist. The research aims to construct a system to collect and concentrate geomagnetic fields, in order to possibly use the concentrated fields for geomagnetic power plants or to integrate the system with a field pick-up unit ...

Badai geomagnet merupakan salah satu fenomena alam terpenting dalam sistem cuaca antariksa yang keberadaannya bersifat acak dan dapat menyebabkan gangguan pada sistem komunikasi HF, navigasi, operasional satelit dan jaringan listrik. Oleh karena itu, pembangunan dan pengembangan software pendeteksi badai geomagnet secara otomatis dengan menggunakan karakteristik Sudden Commencement (SC) sebagai indikator masukannya sangatlah diperlukan. Hal ini dikarenakan jika pendeteksian dilakukan secara manual, pengamat harus melakukan monitoring data selama 24 jam sehingga terasa sangat tidak efisien. Dengan ...
