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

Suswa is a broad low shield volcano that is cut by the southernmost caldera of the Kenya rift. The 8 x 12 km caldera is filled by a broad lava cone. An unusual 5-km-wide ring graben, seen here from the west, cuts the lava cone. The ring graben isolates a tilted island block (left). Ol Doinyo Nyukie ("The Red Mountain") forms the summit of Suswa volcano (right). 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.

The central caldera of Suswa, the southernmost caldera of the Kenya rift, contains a 5-km-wide caldera. Construction of an early shield volcano was followed by eruption of voluminous pyroclastic flows and lava flows that accompanied formation of the caldera. The latest eruptions have originated from vents that have issued still-unvegetated lava flows that may be only a century or so old. N is to the top in this NASA Landsat image.

Suswa is the southernmost volcano of the Central Kenya Peralkaline Province (CKPP). The shield volcano has nested summit calderas that are visible in the center of this December 2019 Planet Labs satellite image mosaic (N at the top), with widths of 12 km for the largest caldera and 5.5 km for the inner caldera. More recent lava flows appear darker in this image.
