Summary: | The ionospheric manifestations of geohazards of earthquakes and tsunamis are well documented based on the radio sounding of the medium.In particular, Global Navigation Satellite Systems (GNSS) based ionospheric monitoring provided more insights towards understanding the dynamic coupling between the lithosphere-atmosphere-ionosphere (LAI) during earthquakes and tsunamis. The present paper will brief the concept of LAI coupling and discuss that how the ionospheric signals produced by earthquakes can be inverted to infer the seismic source characteristics of large earthquakes to envisage the propagation time of tsunami waves. The paper concludes by demonstrating that ionosphere based monitoring of earthquakes and tsunamis may facilitate further advancement of existing tsunami warning systems. |
