Earthquakes often occur and result in civilian casualties and huge Damages. However, it is still a challenge to know the detail and nature of earthquakes as well as predict earthquakes up to now due to lack of dense near-field observations and traditional techniques limitations. Nowadays, the atmospheric parameters and ionospheric total electron content (TEC) can be obtained from global navigation satellite system (GNSS) and other remote sensing data, which can be used to investigate the seismo-atmospheric disturbances and may provide insights on the earthquake. In this talk, seismo-atmospheric disturbances from GNSS and other remote sensing data are presented and reviewed, including observations, theory, methods, recent results and characteristics. The ionospheric perturbations are generated close to the epicenter as acoustic-gravity waves and the atmosphere/ionosphere acoustic and gravity waves by surface Rayleigh waves and tsunamis respectively. These waves are induced by solid-earth/ocean and atmosphere coupling at the ground or ocean interface with the atmosphere propagating upward until the ionosphere create strong perturbation in plasma density and plasma velocity.
