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.

CVGHM reported that on 1 January, a phreatic eruption from Dempo resulted in a strong sulfur odor and "ash rain" that was noted as far as about 10 km from the summit.
MVO reported that during 26 December-2 January activity from Soufrière Hills lava dome was characterized by significantly increased lava extrusion, ash emissions, and pyroclastic flows. Lava extrusion on the top, N, W, and SW sides of the dome continued. Large incandescent blocks, deposited by rockfalls and pyroclastic flows, were visible on multiple occasions at night.
The Smithsonian's Global Volcanism Program seeks better understanding of all volcanoes through documenting their eruptions — small as well as large — during the past 10,000 years.
