PVMBG reported that the eruption at Lewotolok continued during 3-9 July. White-and-gray ash plumes rose as high as 300 m above the summit and drifted W and NW during 3-4 July. Daily white steam-and-gas emissions rose as high as 400 m above the summit and drifted NW and W on the other days during the week. Summit incandescence was visible in webcam images during the week; incandescent material being ejected above the summit was visible in a 6 July image. 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.
