Meru (Tanzania)

Status Unknown Eruption 1910 4565m
Stratovolcano (Rift zone / Continental crust (> 25 km))

Meru

Seen from the west, Meru has a conical profile but it contains a 5-km-wide breached caldera on the E side that formed about 7800 years ago when the summit collapsed. Associated massive debris avalanches and lahars traveled as far as the W flank of Kilimanjaro volcano. Parasitic cones and lava domes are located on all sides; a maar field is present on the lower N flank. The historically active Ash Cone forms a prominent symmetrical cone inside the breached caldera. A second vent between it and the caldera headwall has fed lava flows that cover much of the caldera floor.

Meru volcano (upper right), Africa's fourth highest mountain, is seen from the ice-covered summit plateau of neighboring Kilimanjaro volcano. The 4565-m-high Meru stratovolcano 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. A massive debris avalanche and lahar traveled to the east as far as the western flank of Kilimanjaro volcano.
