Erta Ale


13.601°N, 40.666°E; summit elev. 585 m

All times are local (unless otherwise noted)

The November expedition . . . was organized by Haroun Tazieff in connection with a film about his volcanological work, produced by Gaumont Television. Climbers who descended into the active crater were Luigi Cantamessa (Géo-découverte), Gilbert Pareau (Association of Alpine Guides of Chamonix) Marc Vigny (SVG), Pierre Villemin (cameraman), Alain Curvelier (sound engineer), and Andre Schussele (medical doctor).

Geological Summary. The Erta Ale basaltic shield volcano in Ethiopia has a 50-km-wide edifice that rises more than 600 m from below sea level in the Danakil depression. The volcano includes a 0.7 x 1.6 km summit crater hosting steep-sided pit craters. Another larger 1.8 x 3.1 km wide depression elongated parallel to the trend of the Erta Ale range is located SE of the summit and is bounded by curvilinear fault scarps on the SE side. Basaltic lava flows from these fissures have poured into the caldera and locally overflowed its rim. The summit caldera usually also holds at least one long-term lava lake that has been active since at least 1967, and possibly since 1906. Recent fissure eruptions have occurred on the N flank.
