12 November-18 November 2008

Night-time satellite imagery from 8 November of the eruption that began on 3 November near Dalaffilla and Alu volcanoes revealed a multi-lobed lava-flow field with a primary channelized flow that traveled NE. The source appears to be a one or more NW-SE-trending eruptive fissures NW of Dalaffilla. The flow field on the 8 November image was an estimated 9.3 km long and 3 km wide, with an area of about 15 square kilometers. Thermal anomalies detected by satellites were present during 12-16 November.

5 November-11 November 2008

An eruption of a volcano NW of Erta Ale in Ethiopia's Afar region began on 3 November. Satellite imagery showed a large sulfur dioxide cloud that drifted E over the Arabian Peninsula. According to news articles, observers reported ground shaking, hearing loud noises and explosions from a distance, and seeing smoke. Widespread lava flows were also noted. Extensive thermal anomalies near Dalafilla and Alu volcanoes were detected, consistent with lava effusion, although the source of the lava flows was not known. Thermal anomalies continued to be detected during 3-11 November.

Dalaffilla, also referred to as Gabuli, is a small, but steep-sided conical stratovolcano that rises 300 m above surrounding lava fields SE of Alu volcano. This morphology, unusual for the Erta Ale Range volcanoes, results from the extrusion of viscous, silicic lava flows with primary slopes up to about 35 degrees. These silicic flows extend primarily to the east; on the west they are blocked by walls of a horst structure along the crest of the Erta Ale range. Other basaltic lava flows from regional fissures surround the 613-m-high volcano. Fumarolic activity occurs in the 100-m-wide summit crater and has weathered surrounding lava flows. The first historical eruption of Dalaffilla took place in 2008, when lava flows from W and NW flank vents traveled to the NE.
