Abstract：
A large earthquake usually causes great loss of life and property so people want to find it out and even predict it. Based on the remote sensing techniques, it has been found that most of devastating earthquakes can induce significant disturbances in the atmosphere including the upper atmosphere, i.e., ionosphere, which reveals the lithosphere-atmosphere-ionosphere coupling. On the other hand, an earthquake near or under the oceans often create tsunamis, which tsunami waves can also generate atmospheric and ionospheric waves propagating across the open ocean for a long distance. In this talk, related observation based on ground-based GPS networks in order to detect and trace the seismic and tsunamigenic signatures in the ionosphere is introduced, which opens another window to seek how seismic waves and tsunami waves go and to track where the epicenters and the tsunami origins are.
