Fuerteventura is the oldest island in the Canary Islands dating back 20 million years to a volcanic eruption from the Canary hotspot. The majority of the island was created about 5 million years ago and since then has been eroded by wind and other weather. On the seabed off the west coast of the island rests a block of rock 22 km long and 11 km wide, which appears to have slid off the island largely intact at some point in prehistory, similar to the predicted future collapse of Cumbre Vieja. The last volcanic activity in Fuerteventura was between 4,000 and 5,000 years ago.
