Alex Assenmacher used a DJI Phantom 3 drone to create this stunning aerial view of Tenerife, the largest of the Canary Islands. Most of the video was shot around Mt. Teide, the great stratovolcano rising up from the Atlantic floor which created the island. With a peak elevation of 3.7k meters (12.2k ft.) it's the highest mountain on Spanish territory. Measured from the floor of the ocean, it's the highest volcano in the world outside of Hawaii. Its last eruption occurred in 1909.
