First ionospheric images of the seismic fault slip on the example of the Tohoku-oki earthquake

Astafyeva, Elvira Lognonné, Philippe Rolland, Lucie

[1] 1Hz GPS measurements from the Japanese GPS network GEONET allowed to retrieve information on the seismic fault of the great M9.0 Tohoku-oki earthquake from the ionosphere total electron content (TEC) measurements. The first arrival of the TEC perturbation was registered 464 seconds after the earthquake 140 km on the east from the epicenter....

The Ionospheric view of the 2011 Tohoku-Oki earthquake seismic source: the first 60 seconds of the rupture

Bagiya, Mala Thomas, Dhanya Astafyeva, Elvira

Using the specific satellite line of sight geometry and station location with respect to the source, thomas et al. [Scientific Reports, https://doi.org/10.1038/s41598-018-30476-9] developed a method to infer the detection altitude of co-seismic ionospheric perturbations observed in Global Positioning System (GPS)-Total Electron Content (TEC)...
