AbstractThe Detection of Electromagnetic Emissions Transmitted from Earthquake Regions (DEMETER) microsatellite-monitored data (IAP and ISL) were employed in investigating pre- (30 days) and post- (10 days) perturbations in ionospheric parameters associated with the M6.8 Eastern Honshu (Japan) earthquake (EQ) of July 23, 2008. The results constrain...
Localized regions of low geomagnetic intensity such as the South Atlantic Anomaly allow energetic particles from the Van Allen radiation belt to precipitate into the atmosphere and have been linked to a signature in the form of red aurora-like airglow visible to the naked eye. Smoothed global geomagnetic models predict a low-intensity West Pacific ...
AbstractIntegrated geological, geophysical, geochemical, and botanical studies in the Kuraika River Valley (Kurai Ridge, Gorny Altai) have revealed sharp changes in the growth environment of blue honeysuckle (Lonicera caerulea) at the conjunction zone of the regional Kubadra and local active faults. A high-gradient magnetic field is accompanied by ...
Abstract: Geomagnetic anomalies of different nature observed in the area of Popocatepetl volcano are presented and analyzed in the current paper. The analysis reveals some anomalies considered to be of local volcanic origin: the EM background in the vicinity of the volcano was found to be significantly noisier than other reference stations; sporadi...
This paper presents a multi-objective evolutionary algorithm of bio-inspired geomagnetic navigation for Autonomous Underwater Vehicle (AUV). Inspired by the biological navigation behavior, the solution was proposed without using a priori information, simply by magnetotaxis searching. However, the existence of the geomagnetic anomalies has significa...
