PVMBG reported that the eruption at Lewotolok continued during 22-28 June. An eruptive event was recorded at 2235 on 24 June by the seismic network, though the event was not visually observed. The Alert Level remained at 3 (on a scale of 1-4) and the public was warned to stay 3 km away from the summit crater, and 3.5 and 4 km away from the crater on the SE flank and E and NE flanks, respectively.

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.
