Bridges from space to ground for deeper insight into geophysical extreme events
Convener: Gianfranco Cianchini | Co-conveners: Georgios Balasis, Xuemin Zhang, Angelo De Santis, Dimitar Ouzounov
Extreme geophysical events, such as volcanic eruptions, earthquakes, typhoons, hurricanes, and strong magnetic storms, may produce intense effects on the ground, in the atmosphere, and in the ionosphere before, during, and after their occurrence. The present orbiting satellite missions of Swarm and CSES, primarily dedicated to studying the electromagnetic fields and the plasma of the ionosphere, are an essential opportunity to build bridges between different domains and integrate other data from the ground to improve our capability to follow the preparation, occurrence, and evolution of these extreme events. The joint observational approach includes analyzing the anomalies in different geophysical fields, including satellite, GPS, and in-situ observations. A recent example was the big 2022 Hunga Tonga eruption when the effects of this event on the atmosphere and ionosphere were found worldwide. Other significant effects are expected during the preparation and the occurrence of large-magnitude earthquakes. Coordinated studies of extreme geophysical events can provide new insights into Earth’s geosphere coupling channels. This session welcomes studies of extreme events from space and ground and attempts to integrate, model, and interpret the effects detected in separate geolayers.
