Autonomous drones measure volcanic gas clouds, offering clearer eruption warning signs

To better assess the danger posed by volcanoes, researchers at the Technical University of Munich (TUM) have developed a new measurement system. Laser beams are sent through escaping gas clouds and reflected by drones. An algorithm uses the reflected signals to generate a map sho
