Impacts of the nature hazards are not limited to a specific geosphere but often impact multiple geospheres, subsequently affecting human life significantly. Natural hazards in the Earth system, such as earthquakes, tsunamis, landslides, volcanic eruptions, cyclones, and extreme weather, originate primarily in the lithosphere and troposphere, but they also affect the upper atmosphere and ionosphere. Monitoring the atmospheric and ionospheric disturbances associated with these hazards is beneficial for nowcasting their occurrences.
Solar activities, on the other hand, can induce geomagnetic storms that disturb the atmosphere through magnetosphere-ionosphere coupling. These disturbances can impact satellite operations, the precision and reliability of global navigation satellite systems, and may cause damage to power supply networks.
Therefore, there is an urgent need for instrumental arrays to monitor useful signals, novel methodologies to retrieve associated data, and numerical simulations to understand the interaction between the lithosphere (including the hydrosphere), atmosphere, and space (LAS).
In this session, we invite scientists interested in studying the interactions between the lithosphere (including the hydrosphere), atmosphere, and space. This includes, but is not limited to, natural hazards. The interaction between the multiple geospheres can be excited by numerous potential sources, ranging from lithospheric activities in the Earth’s interior to solar activities in the space beyond the Earth system. We welcome observations of parameters in one geosphere interacting with others, methodologies for detecting signals related to changes in other geospheres, and the construction of numerical models spanning multiple geospheres. The session aims to integrate scientists from distinct fields to improve and enhance our understanding of LAS interactions. Ultimately, this research aims to mitigate the loss of human life and property associated with natural hazards from both Earth and space.
