Cover Story: Drones help to measure and monitor geyser geothermal fields. Some geothermal fields contain hundreds of thermal point-like vents, which are only visible on thermal infrared imagery. A new study shows that it is possible for such geysers to suddenly explode, posing a threat to tourists and changing the environment. View this paper
