Dinamika tektonik Pulau Jawa menyebabkan terjadinya kegempaan yang tinggi dan terbentuknya pola struktur. Besar dan arah kuat medan geomagnet selalu berubah akibat pengaruh variasi sekular. Penelitian ini bertujuan meninjau secara kualitatif ada tidaknya penyimpangan pola pergerakan sudut deklinasi sebelum dan sesudah terjadinya gempa bumi signifikan. Data deklinasi yang digunakan bersumber dar…
With the awareness that the Earth has a magnetic field, its mathematical description, discovery of remanent magnetisation in rocks and discovery of the periodic reversals of the geomagnetic field polarity, geomagnetism within geophysics became an interesting field of study. This is primarily due to advances in measurement technology and improved understanding of the magnetic field and its fluct…
The main magnetic field of the Earth is a complex physical phenomenon. This book presents in detail the foundations of geomagnetism, developed from first principles. The book starts with an overview of the phenomena of interest in geomagnetism, and then goes on to deal with the phenomena in detail, building the necessary techniques in a thorough and consistent manner. Students and researchers w…
