[M-IS12] Planetary Volcanology

Sun. May 24, 2026 9:00 AM - 10:30 AM 103 (International Conference Hall, Makuhari Messe)

Chairperson:Noguchi Rina(Faculty of Science, Niigata University), Morota Tomokatsu(Department of Earth and Planetary Science, The University of Tokyo), Geshi Nobuo(Earth and Planetary Science, Faculty of Science, Kyushu University)

Volcanoes exist on solid planetary surfaces across the solar system. They inform us about volcanism itself, tectonic/internal activity, the surface environment in which they were formed, and their subsequent evolution. Recent high-resolution remote sensing data on extraterrestrial bodies allows us to analyze outcrop scales. Now, we are poised to share the research targets that extend beyond general volcanology and planetary science. Because some geomorphological and geological environments on other planets are similar to those on Earth, research on volcanic geomorphology and geology on Earth provides suitable terrestrial analogs for understanding planetary volcanology. This session discusses the formation history and mechanism of volcanoes across the solar system.
