The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that white-and-gray emissions at Iya rose as high as 300 m above the crater rim and drifted NE, N, W, and SW during 13-14 November. White plumes rose 100-300 m above the crater rim and drifted in multiple directions during the rest of the week. The Alert Level remained at 3 (on a scale of 1-4) and the public was warned to stay 3 km away from the active crater area in all directions and 5 km away to the south.

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.
