BackgroundLate-stage activity of the Kyejo (Kieyo) trachytic stratovolcano, NW of Lake Malawi (Lake Nyassa), consisted of the formation of numerous maars and cinder cones. Kyejo stratovolcano, rising to 2175 m, is elongated in a NW-SE direction and has been active since the mid-Pleistocene. Maars, some of which contain lakes, surround the Kyejo area, and young basaltic cinder cones and lava flows cover an extensive area south of Kyejo. The latest eruption around 1800 AD took place from two parasitic tephritic cones, Sarabwe and Fiteko, that were constructed along a NW-trending fissure. The eruption produced lava flows that traveled 8 km and overran several villages.
