[Couplages Terre–ionosphère, orages magnétiques, précurseurs sismiques et sylphes : résultats et prospects du système [SQUID]2 au laboratoire souterrain de Rustrel-Pays dʼApt]
Grâce à sa sensibilité et son environnement très bas bruit, les couplages Terre–ionosphère sont observables par le magnétomètre [SQUID]2 (Superconducting QUantum Interference Device with Shielding QUalified for Ionosphere Detection). Notamment :
- – un mode de résonance de la mésopause excitable par les ondes P ou par champ électrique comme dans lʼheure précédant le séisme de Sichuan en mai 2008 ;
- – les modes S et T de respiration du globe pendant des périodes de calme magnétique et sismique ;
- – lʼintégrale mondiale du signal des orages magnétiques y compris les contributions polaires ;
- – des signaux associés aux sylphes.
High sensitivity combined with an ultra-low-noise environment [SQUID]2 magnetometer (Superconducting QUantum Interference Device with Shielding QUalified for Ionosphere Detection) allows the observation of Earth–ionosphere couplings. Namely:
- – identification of a mesopause resonance mode excitable by P waves or by electric field as during the hour before the Sichuan earthquake (May 2008);
- – S and T breathing modes of the Earth during quiet magnetic and seismic periods;
- – worldwide signal integral of magnetic storms including polar contributions;
- – signals in time correlation with sprites (Transient Luminous Events).
