Silicate volcanism has fundamentally shaped the surfaces and interiors of terrestrial bodies, including Mars, the Moon, Venus, and Io. From extensive ancient volcanic eruptions to geologically recent activity, volcanic processes play a key role in interior thermal evolution, crustal production, atmospheric replenishment, and regulation of habitable environments. Recent observations of diverse eruption styles on Mars, potentially ongoing activity on Venus, and anomalously young volcanism on the Moon, have challenged established timelines of volcanic and thermal evolution. Many questions still remain regarding the mechanisms of volcanic processes across different planetary environments, eruption styles, and atmospheric interactions, making a review and discussion of these processes across multiple planetary bodies timely. This session invites contributions that advance our understanding of planetary volcanism, including through numerical modeling, remote sensing analyses, in situ observations, and terrestrial analog studies. Contributions focusing on individual bodies and/or cross-body comparisons are welcome.
