The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that daily white emissions at Iya rose as high as 308 m above the cater rim and drifted in multiple directions during 23-29 October.

Geological Summary. Gunung Iya is the southernmost of a group of three volcanoes comprising a small peninsula south of the city of Ende on central Flores Island. The cones to the north, Rooja and Pui, appear to be slightly older and have not shown historical activity, although Pui has a youthful profile (a reported 1671 eruption of Pui was considered to have originated from Iya volcano). Iya, whose truncated southern side drops steeply to the sea, has had numerous moderate explosive eruptions during historical time.
