PVMBG reported that the eruption at Lewotolok continued during 16-22 August. On most days white steam-and-gas plumes rose as high as 500 m above the summit and drifted W and NW. White-and-gray ash plumes rose 100-300 m and drifted W and NW on 16 August. Incandescence at the summit was visible in a webcam image from 19 August. Possible ash plumes were visible in webcam images on most days, especially in an image from 1735 on 20 August. 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.
