Drones used to research Guatemala's Volcano

Drones are helping volcanologists get closer than ever before to Guatemala’s Volcan de Fuego, near some 60,000 people who are at risk from its frequent eruptions. During a 10-day research trip, the team carried out several flights at the summits of both Volcan de Fuego and Volcan de Pacaya, which is also in Guatemala. Using lightweight modern sensors they measured temperature, humidity and thermal data within the volcanic clouds and took images of multiple eruptions in real-time. This is one of the first times drones have been used to gather data from volcanoes such as Fuego, where the lack of close access has retarded research. The drones were flown at distances of up to 8 km away and a height of over 3 km above the launch site.
