Wai Sano is a low, elliptical caldera, 3.5 x 2.5 km wide, at the western end of Flores Island. Wai Sano contains a large caldera lake whose surface is 260 m below the 903 m high point on the southern caldera rim. The SE caldera wall truncated the slopes of 1632-m-high Gunung Cerak. Two solfataras are located at the SE shore of the lake. No historical eruptions are known from Wai Sano, which was mapped as Holocene in age (Ratman and Yasin, 1978).
The Global Volcanism Program is not aware of any Holocene eruptions from Wai Sano. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Wai Sano page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
