The natural hazards in the northern part of the Malawi rift are evaluated. In this area all types of risks related to a rift zone are present. The seismic activity is intense and concentrates along the major NW-trending fault zones which extend into the lake. Numerous explosive volcanic eruptions occurred in the region during Pleistocene time; the Kiejo volcano, which still vents C02 from fissures, erupted in the late 1800's. The whole area is shown to experience regional tectonic tilting due to subsidence along the Livingstone fault bounding the eastern side of the lake. Furthermore, extensive accumulation of gas is present under a shallow cover of sediments over large areas in the northern part of the lake. Gas erupts in the lake along a NNW trending active fault: it consists of a mixture of C02 and CH4.
