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.
