A spectacular video from the National Geographic: explorer Sam Cossman operated camera-mounted drones to capture high-definition images of the Marum (also spelled Maroum) crater in Ambrym, Vanuatu. Vanuatu is a Pacific island nation located in the South Pacific Ocean.
Cossman and his team piloted the drones over the 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.
Here another wonderful video was taken at the Marum volcano in 2014: the GoPro production crew travels to the Marum Crater on Ambrym Island in Vanuatu to join adventurer photographers Geoff Mackley and Bradley Ambrose, the first people to set foot at the edge of a boiling lava lake.
Ambrym is a volcanic island in Malampa Province in the archipelago of Vanuatu. It is actually a large basaltic volcano which has a massive, 1900-year-old, 12 kilometers (7.5 mi) × 8 kilometers (5.0 mi) caldera. The caldera is the site of two active volcanic cones, Benbow and Marum. Often, both Marum and Benbow (as well as other craters) contain small lava lakes, which occasionally erupt lava flows onto the caldera floor, or even exit the caldera through erosion gaps.
