PVMBG reported that the eruption at Lewotolok continued during 23-29 August. Daily white steam-and-gas plumes rose as high as 500 m above the summit and drifted W and NW, though the plumes in the webcam images in the reports appeared to contain ash. White-and-gray ash plumes rose as high as 500 m and drifted on 28 August. Volcano Observatory Notices for Aviation (VONAs) described ash plumes rising 700 m and drifting W and NW at 1409 on 23 August and 1603 on 24 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.
