  author={Takuya Iwata and Ken Umeno},
  journal={arXiv: Geophysics},
We can observe the changes of Total Electron Content, TEC, in ionosphere by analyzing the data from GNSS satellites. There are many reports about TEC anomalies after earthquakes, i.e. large earthquakes often disturb the ionosphere. Up to now, preseismic TEC anomalies have been reported in several papers. However, they are not so clear as coseismic TEC anomalies, and their analysis methods have some problems for practical earthquake prediction. One factor making it difficult to detect TEC…

Mw dependence of the preseismic ionospheric electron enhancements

Ionospheric electron enhancement was reported to have occurred ~40 min before the 2011 Tohoku‐oki (Mw9.0) earthquake, Japan, by observing total electron content (TEC) with Global Navigation Satellite

Preseismic TEC Changes for Tohoku-Oki Earthquake : Comparisons Between Simulations and Observations

Earthquake precursors can be used for earthquake prediction to reduce the loss of resources and human lives. Pre-earthquake ionospheric signatures have been reported by many scientists. Among those,

Ionospheric disturbances detected by GPS total electron content observation after the 2011 off the Pacific coast of Tohoku Earthquake

All the details of ionospheric disturbances following the 2011 Tohoku Earthquake were first revealed by the high-resolution GPS total electron content observation in Japan. The initial ionospheric

Ionospheric electron enhancement preceding the 2011 Tohoku‐Oki earthquake

The 2011 March 11 Tohoku‐Oki earthquake (Mw9.0) caused vast damages to the country. Large events beneath dense observation networks could bring breakthroughs to seismology and geodynamics, and here I

GPS detection of ionospheric perturbations following the January 17, 1994, Northridge Earthquake

Sources such as atmospheric or buried explosions and shallow earthquakes producing strong vertical ground displacements are known to produce pressure waves that propagate at infrasonic speeds in the

Coseismic ionospheric disturbance of the large strike-slip earthquakes in North Sumatra in 2012: Mw dependence of the disturbance amplitudes

We studied ionospheric responses to the 2012 April 11 Mw8.6 North Sumatra earthquake using total electron content (TEC) measurements with the regional Global Navigation Satellite System (GNSS)

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

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)

Ionosphere plasma bubbles and density variations induced by pre‐earthquake rock currents and associated surface charges

[1] Recent ionospheric observations indicate that the total electron content (TEC) may anomalously decrease or increase up to 5–20% before the occurrence of big earthquakes. The ionospheric density

An improved coupling model for the lithosphere‐atmosphere‐ionosphere system

In our previous model for the lithosphere‐atmosphere‐ionosphere coupling, the background magnetic field was assumed to be perpendicular to the horizontal plane. In the present paper, we improve the
