Deadly forest fires ignited in central Portugal on June 17, 2017, amid dry, hot conditions.
Burning continued overnight and into the next day, visible in this image captured at 12:10 p.m. local time (11:10 Universal Time) on June 18, 2017, with the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Smoke billowed toward the north, and is also visible to the east in Spain. The red outlines are areas where the satellite detected heat signatures indicative of active burning.
The fires burned in the mountainous areas of Pedrógão Grande, a municipality located about 160 kilometers (100 miles) northeast of Lisbon. The country’s forested landscape is prone to burning and has seen a number of large-scale fires when conditions are warm and dry. The ignition of this fire was initially attributed to lightning.
