Photo Gallery

The impressive 5 x 8 km summit caldera of Silali volcano is seen in an aerial view from the SE. Formation of the 300-m-deep caldera is related to the incremental eruption of basaltic and trachytic lava flows about 63,000 years ago. N-S-trending rift valley faults cutting across the volcano can be seen at the lower left. Some of the youthful parasitic cones on the caldera floor and flanks of Silali, the largest volcano of the northern Gregory Rift, may be little more than a few hundred years old.
