PVMBG reported that the eruption at Lewotolok continued during 17-23 January. White gas-and-steam plumes rose 300 m above the summit and drifted NE, E, and SE during 17-20 January; emissions were not visible on the other days. Incandescent material was occasionally ejected above the vent, sometimes as high as 400 m. 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.
