Correlation Between Climate Change and Tectonic Activity by Lake Rukwa, Tanzania

Tanzania – June 26th, 2013

Scientists have found a correlation between climatically induced lake level change in Lake Rukwa, seismo-tectonic activation of the regional fault network (underneath Lake Rukwa and the Kanda fault between Lakes Rukwa and Tanganyika) and the timing of the recent strong volcanic eruptions in the Rungwe Volcanic Province.

This relationĀ is explained taking into account that Lake Rukwa is very sensitive to climate change as it occupies a flat depression and its overflow outlet is 180 m above its present-day level. Its lake level rises rapidly when the climate becomes more humid. Increases in lake level mean an increase in the load in the basin and perturbation of the ambient tectonic stresses (click here for more information).

Fires Near Lakes Tanganyika, Rukwa and Malawi

Zambia and Tanzania – July 29th, 2012

Plumes of smoke from many fires can be seen burning in Tanzania (upper right), Zambia (below) and the Democratic Republic of the Congo (upper left), around lakes Tanganyika (upper left), Rukwa (center) and Malawi (lower right). In general the smoke is blowing towards the west or northwest.

DRC and Zambia – July 11th, 2012

Smoke from hundreds of fires in the Democratic Republic of the Congo (above, left) and Zambia (below), creates a haze over the two countries. Through the haze, plumes of smoke from many individual fires can be discerned. The haze is having little effect on the visibility of Lakes Tanganyika (top edge), Rukwa (tan from sediments) and Malawi (parallel to right edge).

Tanzania – July 5th, 2012

Plumes of smoke from many wildfires can be visible across Tanzania, east of Lake Tanganyika (center), south of Lake Victoria (top right) and north of Lake Rukwa (tan, bottom right). Most of the plumes of smoke are blowing northward or northwestward. They tend to be thicker and more fanned out towards the south, indicating differences in wind strength and direction.

Lakes Malawi and Rukwa in East Africa

Malawi, Mozambique, Tanzania - November 22nd, 2011

Two large African lakes can be observed here: the brownish grey Lake Rukwa (upper left corner) and the elongated, dark blue Lake Malawi (also known as Lake Nyasa).

Lake Malawi is an African Great Lake and the southernmost lake in the Great Rift Valley system of East Africa. This lake, the third largest in Africa and the eighth largest lake in the world, is located between Malawi, Mozambique, and Tanzania. It is the second deepest lake in Africa.

Lake Rukwa is an alkaline lake in southwestern Tanzania, lying midway between Lake Tanganyika and Lake Nyasa at an elevation of about 800 metres, in a parallel branch of the rift system. The lake has seen large fluctuations in its size over the years, due to varying inflow of streams. Currently it is about 180 km long and averages about 32 km wide, making it about 5760 square kilometres in size.
