Background:

Rungwe volcano, the largest in the Karonga basin NW of Lake Malawi (Lake Nyasa), is cut by a 4-km-wide caldera that is breached to the WSW. Hummocky terrain from a debris-avalanche deposit produced by collapse of the summit and western flank extends at least 20 km SW of the volcano. The trachytic caldera is largely filled by a series of youthful-looking uneroded and sparsely vegetated pumice cones, lava domes, and explosion craters. The latter are also found on the southern and northern flanks. A large area of basaltic cones and lava flows are found on the NW flank of the volcano, and youthful-looking lava flows extend to the SW from vents inside the caldera. Rungwe produced explosive and effusive eruptions during the Holocene; the largest explosive eruption took place about 4000 years ago and the most recent about about 1200 years ago.
