PVMBG reported that the eruption at Lewotolok continued during 4-10 October. White-and-gray ash plumes rose 250 m above the summit and drifted N and NW on 4 October. The next day a Volcano Observatory Notices for Aviation (VONA) was issued for a gray ash plume that rose as high as 700 m and drifted W. Ash plumes rose 200-500 m and drifted N, NW, and W on 8 and 10 October. On the other days during the week white steam-and-gas plumes were visible rising as high as 500 m and drifting N, NW, and W. At 2024 on 9 October a webcam image captured incandescent material being ejected above the summit. 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.
