Some geologists, though, consider the Kuma-Manych depression as the geological border between Asia and Europe. Such definition would render Elbrus entirely in Asia, making it the highest volcano of that continent (see below) and making Mount Etna (a 3350-metre active stratovolcano in Sicily, Italy) the highest volcano in Europe. Mount Teide in the Canary Islands, while active, taller than Etna and within the territory of a European country, would not be considered because geologically the Canaries belong to the African continent.
