The forested lava flow (left foreground) was erupted on the caldera floor of Fentale volcano in 1820. This view looks from the NE. The walls of the 3 x 4 km summit caldera are up to 500 m high. During the 1820 eruption, basaltic lava flows were also extruded onto the Main Ethiopian Rift from a 4-km-long fissure on the south flank.
