As can be seen in the image taken by Deimos-1 yesterday, July 2nd 2012, at 12.11 local time, the two fire events have significantly affected forested areas of the Province de Valencia and are easily identifiable from space. The fire event that broke out last Friday (June 29th) in the town of Andilla is still partially active and some smoke plumes are visible in the image obtained on Monday morning (Figure 2). Fire burned extensive areas of the regional districts of Los Serranos, Campo de Turia and Alto Palancia. Using another Deimos-1 image acquired a few days before the event started (Figure 1), Elecnor Deimos Imaging has generated a fire map concluding that about 17,333 hectares were burned as of Monday morning (Figure 3, 4 and 5). On the other hand, Deimos-1 image partially shows the fire event that broke out last Thursday (June 28th) in the village of Cortes de Pallás, which rapidly spread in the forested landscape and burned thousands of hectares in the regional districts of Hoya de Buñol, Valle de Cofrentes, Canal de Navarrés and Ribera Alta. As for the Andilla fire event, and using the partially available information (Figure 6), Elecnor Deimos Imaging estimates that about 19,177 hectares were burned as of Monday morning in the surroundings of the villages of Dos Aguas, Millares and Catadau. The west sector of the fire scar will be further characterised shortly with new acquisition of Deimos-1 images.

In the coming days Elecnor Deimos Imaging will continue monitoring the two fire events with the aim of assessing the status of the affected areas and estimating the total amount of hectares affected by the fire. Once again the capacity of the Deimos-1 Earth Observation System when dealing natural disasters and crisis has been demonstrated.
The Deimos-1 Earth Observation system, comprising the satellite and its whole ground segment, is fully owned by Elecnor Deimos, the technology division of Elecnor. Elecnor Deimos Imaging, the Remote Sensing branch of Elecnor Deimos, operates and manages all the assets of the mission in order to generate and market high-resolution images and derived products characterising Earth’s surface. Their use covers various applications, such as agriculture, environment monitoring, climate change, security, deforestation and water resources control, and the support to relief activities during natural disasters.
The imaging instrument on-board the Deimos-1 satellite produces images of the Earth surface in three different spectral bands with a detail of 22 metres, and a large swath that covers up to 620 km. The satellite circles the Earth 15 times per day, and is capable of acquiring an image of any area of the world every three days.
