Global Volcanism Program | Image GVP-11154
The dark lava flows at the right side of this Landsat image are from vents at the western end of the Chyulu Hills volcanic field. This 100-km-long, NW-SE-trending volcanic field is located 150 km E of the Kenya Rift. Two of the several hundred small cones and flows, Shaitani and Chaimu, erupted during the mid-19th century. Many of the cones are aligned along dominantly NW-trending older faults and younger NNE-trending fissures.
