Behold the 'perfect' cone

That glowing lava is on the tip of the world's most perfectly shaped, symmetrical volcanic cone, which formed after years of eruptions from what is still an active stratovolcano. Mount Mayon, on the island of Luzon in the Philippines, has erupted dozens of times in the past 400 years, with a significant eruption as recently as 2018.
