PVMBG reported that the eruption at Lewotolok continued during 28 February-5 March. Daily white-and-gray ash plumes rose as high as 900 m above the summit and drifted NW, E, and SE. The lava flow on the SE flank was 2 km long and the flow on the S flank was 600 m long; the distal end of the longer flow did not advance, though lava effusion continued, and new flows possibly overlapped the older flows. The Alert Level remained at 3 (on a scale of 1-4) and the public was warned to stay 2 km away from the vent and 3 km away from the vent on the S and SE flank. According to a news article residents were asked to bring their livestock into the villages.

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.
