PS1.6 | Planetary tectonics, volcanism, and seismicity
Planetary tectonics, volcanism, and seismicity
Convener: Iris van ZelstECSECS | Co-conveners: Barbara De Toffoli, Alexander Stott
To truly understand the surface features and inner workings of a planet, its tectonic, volcanic, and seismic processes need to be thoroughly studied. To do so, many different methods exist including numerical and analogue modelling studies, lab experiments on rock rheology and environmental conditions, detailed geological mapping, and theoretical geophysical studies of a planet’s available data, such as topography and gravity. To further complement these studies, missions are an invaluable addition to gather data on the various planetary bodies of interest.

Indeed, from a mission perspective, we are set to learn a lot about planetary tectonics, volcanism, and seismicity in the coming decades as BepiColombo reaches Mercury to study its geology and tectonics, the VERITAS and EnVision missions will study the current tectonic and volcanic activity of Venus, and Dragonfly promises a wealth of seismological observations of Titan. As the recent InSight mission showed, these missions have the power to transform our understanding of a planetary system. Looking even more towards the future, it is also expected that seismology will return to the (farside of the) Moon with the selection of the Farside Seismic Suite on a commercial lander in the next few years and the Lunar Geophysical Network remains an encouraged mission concept for a future NASA New Frontiers call.

Here, we aim to bring together contributions that use a range of different methods (modelling, mapping, missions, etc.) to study the tectonics, volcanism, and seismicity of planetary bodies such that different communities may learn from each other in their quest to more thoroughly understand the workings of rocky and icy planets, moons, asteroids, and comets.
