Video technology and science converge on an active volcano in Vanuatu, where explorer Sam Cossman operated camera-mounted drones to capture high-definition images of the spectacular yet dangerous Marum Crater of Ambrym. Cossman and his team piloted the drones over the 7.5-mile-wide (12-kilometer) caldera while confronting toxic gases and boiling lava. Although two drones succumbed to the harsh environment, the team was able to bring back video and photos that will help scientists learn more about the volcano and the life around it.
Ambrym is a large basaltic volcano with a 12-km-wide caldera, and one of the most active volcanoes of the New Hebrides volcanic arc. The caldera is the result of a huge plinian explosion, which took place around 50 AD. Its explosive force is rated 6, the second highest in the Smithsonian Institution’s Volcanic Explosivity Index ranks of the largest volcanic explosions in recent geological history.
