PVMBG reported that the eruption at Lewotolok continued during 27 September-4 October. White emissions rose as high as 350 m above the summit and drifted E, SE, W, and NW on most days. White-and-gray plumes rose as high 500 m and drifted NW, W, and E during 29-30 September and 1-2 October. The Alert Level remained at 3 (on a scale of 1-4) and the public was warned to stay 3 km away from the summit crater and 4 km away from the crater on the SE flank.

Geological Summary. The Lewotolok (or Lewotolo) stratovolcano occupies the eastern end of an elongated peninsula extending north into the Flores Sea, connected to Lembata (formerly Lomblen) Island by a narrow isthmus. It is symmetrical when viewed from the north and east. A small cone with a 130-m-wide crater constructed at the SE side of a larger crater forms the volcano's high point. Many lava flows have reached the coastline. Eruptions recorded since 1660 have consisted of explosive activity from the summit crater.
