Fires continued to burn around eastern Africa’s Lake Malawi (Lake Nyasa) on October 13, 2009. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this true-color image the same day. The fires were likely set for purposes of agriculture, a common occurrence at this time of year.
Red dots indicate hotspots associated with actively burning fires, which burn all around Lake Malawi. Beige-gray smoke plumes occupy a roughly east-west band through Zimbabwe and Mozambique, south of the lake. Although the smoke almost certainly results from the regional fires, only a few source points for smoke plumes appear in this image.
In Manitoba, Canada, north of Lake Winnipeg, several massive fires were burning on July 23, 2007. Thick plumes of smoke spread east from the forest fires. In previous days, smoke from fires degraded the air quality enough that people in communities near Southern Indian Lake (hidden by smoke to the west of Gauer Lake) had to evacuate.
