According to news articles, 500 people have evacuated their homes on 6 January because of increased activity at Lewotolo. Black smoke rose from the crater and rumbling sounds were reported. On 2 January CVGHM raised the Alert Level from 2 to 3 (on a scale of 1-4).

Geologic Background. Anchoring the eastern end of an elongated peninsula that is connected to Lembata (formerly Lomblen) Island by a narrow isthmus and extends northward into the Flores Sea, Lewotolo rises to 1423 m. Lewotolo is a symmetrical stratovolcano as 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. Historical eruptions, recorded since 1660, have consisted of explosive activity from the summit crater.
