On April 2, 2004, the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite passed over Western Australia and snapped this image scattered fires (marked in red). The majority of the fires are small and located away from dense vegetation (which appears deep brownish-green). This pattern, as well as the season, suggests that these are agricultural fires being set for land management purposes. The smoky fires in the south, however, may be a different type of fire, perhaps wildfires or prescribed burns.
