Lewotolo (or Ile Api Lewotolok) volcano on the eastern end of a peninsula of Lembata (formerly Lomblen) Island forms a perfect symmetrical cone. The stratovolcano has 2 craters of 900x800 m and 250x200 m in diameter.
Many lava flows have reached the coastline. Historical eruptions, recorded since 1660, have consisted of explosive activity from the summit crater.

Introduction:

Lewotolo's lavas are remarkable because they contain the rare mineral zirconolite (CaZrTi2O7).
