More of Africa scarred by fires than thought
04 February 2019
Wildfires can cause devastation and are also to blame for more than a quarter of greenhouse gases being released into the atmosphere. Satellites play a key role in mapping landscape scarred by fire – but the Copernicus Sentinel-2 mission has revealed that there are more fires than previously thought.
From the vantage of space, satellites can be used to detect fires and monitor how they spread and, in the first instance, this can often help relief efforts. However, satellites are also important for mapping the scars that fires leave in their wake, particularly in remote regions.
It is currently estimated that fires contribute 25–35% of total annual greenhouse gas emissions to the atmosphere so more precise information gained from satellite-based scar-burn maps could help to better understand how they add to the greenhouse effect.

When Mount Agung in Indonesia erupted in 2017, the search was on to find out why it had stirred. Thanks to information on ground deformation from the Copernicus Sentinel-1 mission, scientists now have more insight into the volcano's hidden secrets that caused it to reawaken.
