Journal ArticleDOI
Ground-based GPS imaging of ionospheric post-seismic signal
Philippe Lognonné,J. Artru,Raphaël F. Garcia,F. Crespon,Vesna Ducic,Eric Jeansou,Giovani Occhipinti,Jérôme Helbert,Guilhelm Moreaux,Pierre-Emmanuel Godet +9 more
TL;DR: In this article, a continuous global positioning system (GPS) ionospheric tomography above Europe, Japan and California will be performed with the Service and Products of ionosphere Electronic Content and Tropospheric Refractive index over Europe (SPECTRE) experiment.
Journal ArticleDOI
Three-dimensional ionospheric tomography of post-seismic perturbations produced by the Denali earthquake from GPS data
TL;DR: In this article, a tomographic reconstruction of electron density perturbations in the acoustic frequency band is presented, with a timing consistent with an infrasonic wave generated by the path of seismic surface waves.
Journal ArticleDOI
Response of the ionosphere to the seismic trigerred acoustic waves: Electron density and electromagnetic fluctuations
E. Alam Kherani,Philippe Lognonné,Nishant Kamath,F. Crespon,Raphaël F. Garcia,Raphaël F. Garcia +5 more
TL;DR: In this article, the excitation of low-frequency (0001-10 Hz) electromagnetic and density fluctuations in the ionosphere during the passage of seismic triggered acoustic waves (AWs) was studied.
Journal ArticleDOI
Tsunami detection in the ionosphere
J. Artru,Philippe Lognonné,Giovanni Occhipinti,F. Crespon,Raphaël F. Garcia,Eric Jeansou,Makoto Murakami +6 more
TL;DR: In this article, the authors presented some recent results regarding the detection of tsunami waves through perturbations induced in the ionosphere, which can be used to measure the sea surface variation in the case of large tsunamis.
Journal ArticleDOI
Seismic waves in the ionosphere
Philippe Lognonné,Raphaël F. Garcia,F. Crespon,Giovanni Occhipinti,A. Kherani,Juliette Artru-Lambin +5 more
TL;DR: In this article, the authors proposed a method for remote detection of the seismic signals from space, which is based on the detection of very low ground displacements: even at the most noisy frequency, 0.15Hz, associated with a global seismic noise generated by the oceanic waves, the amplitude of the ground displacement noise is in the range of 0.1-10 micrometers and good signal to noise seismic waves have amplitudes of a hundred to a thousand times higher.
