PVMBG reported that the eruption at Lewotolok continued during 1-7 November. White-and-gray ash plumes rose 100-400 m above the summit and drifted W and NW on 1 November. White steam-and-gas plumes rose 50-400 m and drifted W, NW, and E on the other days during the week. Webcam images captured at 1853 on 1 November and 0350 on 3 November showed incandescent material being ejected above the summit. Incandescence at the summit was visible in a webcam image at 2128 on 4 November. The Alert Level remained at 2 (on a scale of 1-4) and the public was warned to stay at least 2 km away from the summit crater.

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.
