Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported continuing activity at Lewotolok during 20-26 March. White-and-gray emissions were observed daily; plumes rose as high as 1 km above the summit. Seismicity included non-harmonic tremor episodes, frequent gas emission signals, and 6-18 daily eruption events. 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 summit crater on the S and SE flank.

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.
