Borawli stratovolcano rises above the eastern shore of Lake Afrera, also known as Lake Giulietti. The upper part of the ~800-m-high conical edifice consists of trachytic lava flows overlying older basaltic flows. Young pantelleritic obsidian domes south of the volcano are the probable source of rounded pumice fragments found around Lake Afrera.

The Global Volcanism Program is not aware of any Holocene eruptions from Borawli. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Borawli 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.

Borawli stratovolcano, located across Lake Giulietti (also known as Lake Afrera) from the Erta Ale Range, rises above the eastern shore of the lake. The upper part of the conical 812-m-high volcano, seen here from the NW, consists of trachytic lava flows overlying basaltic flows. Young obsidian domes south of the volcano are the likely source of rounded pumice fragments found around the lake. Evaporation of water from Lake Giulietti has produced salt crystals that float on the lake surface, forming the while lines at the bottom of the photo.

The Tat Ali volcanic massif extends across the right-hand side of this NASA Landsat image, east of Lake Afrera (center). This basaltic-to-pantelleritic shield volcano displays an elongated central depression partially filled by recent basaltic lava flows. The dark-colored flows at the upper right were erupted from fissures at the northern end of the Tat Ali complex. Borawli volcano lies at the right-center, between Tat Ali and Lake Afrera (also known as Lake Giulietti), and the lava flows at the upper left are from the flanks of the Hayli Dubbi complex.

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.
