People living in the shadow of deadly volcanoes have been given a source of hope with a drone that warns of impending eruptions.
British researchers have built a device that samples the cocktail of gases emitted when they are volatile.
The drone, designed to survey remote sites many of which have not been explored, has been tested over Manam volcano off the northeast coast of Papua New Guinea. Manam has erupted several times in recent decades, forcing people to flee.
A study published yesterday in the journal Science Advances explained that the drone had two fixed wings with a 2m span and could reach an altitude of about 2,300m, staying aloft for about 40 minutes, carrying small gas sensors, spectrometers and cameras.
