The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that there was an increase in activity and potential hazards at Iya, based on visual and instrumental monitoring data during 16-22 October. The Alert Level was raised to 2 (on a scale of 1-4) at 0800 on 17 October, and the public was warned to stay 2 km away from the active crater area.
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.
