Which country has the most active volcanoes?

Indonesia has more active volcanoes than any other country on Earth. The vast island nation is home to well over a hundred active volcanoes, and many of them erupt frequently.

The reason lies in geology. Indonesia sits along the Pacific Ring of Fire, a horseshoe-shaped zone around the Pacific Ocean where the planets tectonic plates meet and grind against one another. Along Indonesia, one plate is forced beneath another, melting rock deep underground and feeding a long chain of volcanoes that runs through islands such as Sumatra, Java, and Bali.

Some of the most powerful eruptions in recorded history have happened in Indonesia. The eruption of Mount Tambora in 1815 was so vast that it disrupted the global climate, leading to a year so cold abroad that it became known as the year without a summer. Krakatoa, which erupted catastrophically in 1883, is another Indonesian volcano whose name became known around the world.
