A set of over 42 Holocene lava flows emanates from the volcano, and covers a surface area of about , with individual lava flows extending up to east and west from between its two neighbours. The lava flows at larger distances are older than the ones close to the vent. These flows are blocky, have lobe structures and reach thicknesses of ; the total thickness of this pile of lava flows is about . Pyroclastic flow deposits are also found, but they might originate from Ampato rather than Sabancaya.
