Recent research has introduced some evidences referring to a possible connection between the variation in geomagnetic field measurements and seismic activities. Thus, the present study focuses on a certain seismic activity that occurred at the northern part of Honshu Island, Japan to find out its impact on the diurnal geomagnetic variations recorded at this region. The study of variability of daily geomagnetic variations amplitude at the northern part of Honshu Island; which is characterized by high seismic activities has introduced motivating results. Data analysis and processing indicate the presence of an unusual change in the diurnal variations amplitude in association with earthquake activity occurred on 24 March 2008 at the studied area. A remarkable anomalous behavior in the diurnal variations amplitude of the East-West horizontal geomagnetic component (D-component) was detecte.. View More»
