In April 2007, the Piton de la Fournaise volcano in eastern Reunion, a French overseas department, was erupting for more than a week.

The eruption resulted in the collapse of the volcano's summit, with magma at times being spewed as high as 200 metres into the air. Besides ash and lava, the volcano also released sulfur dioxide (SO2).
The GOME-2 instrument on Metop-A tracked the emission of SO2 from this volcano from 3 to 10 April, 2007. The image from 7 April shows the larger SO2 plume, transported by the wind to the north-east of the volcano (the greatest SO2 concentrations appear in red). Volcanic SO2 derived from GOME-2 is monitored regularly, in the framework of the Ozone SAF project, at the DLR Institute for Remote Sensing Technology (IMF) and the German Remote Sensing Data Center (DFD).
