All times are local (unless otherwise noted)


PVMBG reported that Lewotolok continued to erupt during 7-13 February. White emissions rose 5-100 m above the summit during 7 February, and 50-100 m above the summit during 10 and 13 February. A seismograph recorded explosive eruptive events at 1754 on 8 February, and 1657 on 9 February; white to gray ash plumes rose approximately 300-500 m above the summit and drifted E and SE. 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.
