PVMBG reported that the eruption at Lewotolok continued during 26 June-2 July. White steam-and-gas emissions rose as high as 400 m above the summit and drifted N, NW, and W during 26-29 July. Emissions were not visible on 30 June. A white-and-gray ash plume rose as high as 300 m above the summit and drifted W and NW during 1-2 July. Summit incandescence was visible in webcam images during the week. The Alert Level remained at 2 (on a scale of 1-4) and the public was warned to stay 2 km away from the vent and 2.5 km away from the vent on the S, SE, and W flanks.

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.
