We analyzed 1 m emissivity anomalies on the eastern flank of Idunn Mons on Venus. We looked for recently active lava flows responsible for these anomalies. We performed the emissivity modeling for five mapped lava flows. Flank lava flows might be responsible for the observed emissivity anomalies. We suggest the post-eruption stratigraphy on the eastern flank of Idunn Mons.
