Eruptive History

There is data available for 4 confirmed Holocene eruptive periods.

1910 Oct 26 - 1910 Dec 22 Confirmed Eruption VEI: 2

Episode 1 | Eruption Ash Cone
1910 Oct 26 - 1910 Dec 22 Evidence from Observations: Reported
 Small ash eruption from Ash Cone. Guest and Leedal (1953) mention activity on 13 and 26 October 1910, but Richard and Neumann van Padang (1957), who cite this report, lists 26 October as the start of the eruption.

An aerial view across the summit plateau of Kilimanjaro looks west towards Meru stratovolcano in the distance. The nested craters in the center are the youngest features of the volcano. They cut a summit ash cone that has grown within a 2.4 x 3.6 caldera, whose rim is seen at the left.

Meru volcano, Africa's fourth highest mountain, rises to the west of its more prominent neighbor, Kilimanjaro. Seen here from the slopes of Kilimanjaro, 4565-m-high Meru is cut by a 5-km-wide breached caldera on the east side that formed about 7800 years ago when the summit of the volcano collapsed. The resulting massive debris avalanche and lahar traveled as far as the western flank of Kilimanjaro volcano. The historically active Ash Cone forms a prominent symmetrical cone inside the breached caldera.

The northern wall of the horseshoe-shaped caldera cutting the summit of Meru volcano rises vertically up to 900 m above the caldera floor. The 5-km-wide caldera is breached to the east and was formed as a result of a massive volcanic landslide about 7800 years ago.

Meru volcano (upper right), Africa's fourth highest mountain, is seen from the ice-covered summit plateau of neighboring Kilimanjaro volcano. The volcano is cut by a 5-km-wide breached caldera on the E side that formed about 7,800 years ago when the summit collapsed. A massive debris avalanche and lahar traveled to the east as far as the western flank of Kilimanjaro.
