Satellite images of Greece’s deadliest wildfires in over a decade show the huge devastation wreaked by the disaster as firefighters continue to battle the flames.

At least 77 people were killed when multiple wildfires swept across Greece’s Attica region. The death toll is expected to rise as rescue crews search for survivors.

An image captured by NASA on July 24 shows the areas surrounding Athens which are still actively burning.

Two huge fires in Greece have flanked Athens, wreaking havoc in two separate areas outside the capital city. On July 24, our eye in the sky spotted the worst fires to hit Greece in at least a decade.🔴 = Actively burning areas Take a look: https://t.co/APi9G2AHl8pic.twitter.com/QQO1jQAhcg — NASA (@NASA) July 24, 2018

Each hot spot, outlined in red, is an area where the thermal detectors recognized temperatures higher than background. The accompanying plumes of smoke, seen in the image, are indicative of fire, NASA said.

The EU’s Earth Observation Programme, known as Copernicus, also snapped some incredible images of the wildfires from space.

Images taken by the Sentinel satellite and shared by German imaging expert Pierre Markuse shows the extent of the Kineta wildfire. Dense smoke clouds can be seen billowing over the charred landscape.

This wildfire really has strong SWIR emissions, look how bright it appears in this SWIR image. It also produces quite dense smoke clouds. #wildfire#Κινέτα#Kinetapic.twitter.com/nm2YgqeFqg — Pierre Markuse (@Pierre_Markuse) July 23, 2018

Meanwhile, aerospace engineer Jorge Garcia examined the spread of nitrogen dioxide from the wildfires – a gas which is toxic if inhaled and which expedites the burning of combustible materials.
