Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Suswa. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Suswa page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Photo Gallery

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.
