PVMBG reported that the eruption at Lewotolok continued during 29 May-4 June. White steam-and-gas plumes rose 100-700 m above the summit and drifted W, NW, and SE during 29 and 31 May, 1-2 June, and 4 June. On 30 May and 3 June white-and-gray ash plumes rose as high as 500 m and drifted W and NW. According to a news article, the lava flow had not advanced by 1 June and remained about 1.3 km long. The Alert Level remained at 3 (on a scale of 1-4) and visitors and residents of Lamawolo, Lamatokan, and Jontona were warned to stay 2 km away from the vent and 3 km away from the vent on the S and SE 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.
