Kaba volcano is located in SW Sumatra, Indonesia. An extinct volcano (Hitam) is located closeby. Kaba Volcano is located at Rejanglebong Regency, Bengkulu, Sumatra. There are 8 craters show historical explosive activity.

The summit area of Kaba volcano contains three high peaks – Bukit Kaba, Bukit Itam (1893 m) and Bukit Malintang (1713 m) with three craters among them called Kaba west-old crater, Kaba middle-new crater and kaba vogelsang crater.

Eruption products include basaltic-andesit lava, pyroclastic flow and pyroclastic fall deposits.

2009 Unrest
Seismic activity has increased at Kaba volcano, Sumatra, Indonesia. On 19th October 2009, 127 shallow volcanic earthquakes were recorded. Continuous tremor occurred on 19th October between 06:40-09:00 hr, and 20th October between 03:00 to 09:00 hr. Visual observations showed thin white emissions rising 50 m above the crater. Ground deformation has been measured across the volcano. Water temperature measurements of the craters on 15th October was 72 deg C, with a degree of acidity (pH) 3.2. Solfatara temperatures range from 106 to 107 deg C. A one kilometre exclusion zone has been placed around the crater. On 20th October 2009 the volcano was raised to alert level 2.

2000 Eruption
On 26-27 August 2000, five small ash emissions, accompanied by earthquakes, occurred at Kaba volcano. The increase in activity occurred after a magnitude 7.8 tectonic earthquake near Bengkulu, Sumatra.

1940 Eruptions
Increased eruptions occurred at Kaba volcano in January-March, June, July, and October 1940.

Kaba, a twin volcano with Mount Hitam, has an elongated summit crater complex dominated by three large historically active craters trending ENE from the summit to the upper NE flank. The SW-most crater of 1952-m-high Gunung Kaba, Kawah Lama, is the largest. Most historical eruptions have affected only the summit region of the volcano. They mostly originated from the central summit craters, although the upper-NE flank crater Kawah Vogelsang also produced explosions during the 19th and 20th centuries.
