Coralie Neubüser received the EMSEV award for an outstanding presentation at the (virtual) IAGA-IASPEI Joint Scientific Assembly 2021. She presented, on behalf of the Limadou collaboration, the ‘Combination of ground and satellite observations of the August 5, 2018 Bayan Earthquake’ in the session “Lithosphere-Atmosphere-Ionosphere Coupling: Seismo Ionospheric and Electromagnetic”.
The session discussed the "unexplored" characteristics of co- and pre-seismic ionospheric and electromagnetic anomalies and their origin within the framework of lithosphere- atmosphere-ionosphere coupling. This included a brainstorming discussion towards the advancement of new insights in realizing the pre-seismic imprints in the near space environment. Observations from ground as well as from space and their validation through model simulations adopting both empirical and physical approaches may assist in understanding the physical mechanisms responsible for these anomalies.

Abstract of the contribution:
Earthquake monitoring plays a key role in human life protection especially in highly populated areas of the earth. First indications have been found in NOAA satellite data, that particle fluxes of trapped electrons in the Van Allen belts can be correlated to seismic activity on the ground. A recent study on the August 5, 2018 Bayan Earthquake (EQ) shows and explained via an analytical model the coupling among the lithosphere, the atmosphere, the ionosphere and the magnetosphere, through the generation of an acoustic gravity wave (AGW) able to mechanically perturb the ionospheric plasma density which in turn generates electromagnetic waves propagating through the magnetosphere. In this contribution, we will investigate the magnetosphere-ionosphere system from the particle point of view during the same EQ event. We will use the measurements of low-energy electron flux measurements of the HEPD and HEPP instruments on-board CSES-01 satellite to search for particle bursts which can be related to the EQ event.
