Popis:
The central caldera of Suswa, the southernmost caldera of the Kenya rift, contains an unusual 5-km-wide circular graben that isolates a tilted island block of caldera-floor lava flows. Construction of an early shield volcano was followed by eruption of voluminous pumice flows and lava flows that accompanied formation of the caldera. The latest eruptions of Suswa have originated from parasitic vents that have issued still-unvegetated lava flows that may be only a century or so old. North is to the top in this NASA Landsat image.
