PVMBG reported that the eruption at Lewotolok continued during 14-20 June. White-and-gray ash plumes rose as high as 400 m above the summit and drifted W and NW during 15 and 17-18 June; white steam-and-gas emissions were visible on the other days. Strombolian explosions at the summit crater were visible in webcam images at 2242 on 14 June, 2137 on 17 June, and 2213 on 18 June. 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 in all directions.

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.
