Countries by Number of Active Volcanoes

About This Dataset

Countries ranked by the number of volcanoes classified as active within their territory according to the Smithsonian Institution Global Volcanism Program. Indonesia sits atop the volcanic activity rankings with 139 active volcanoes — a consequence of its position at the intersection of three major tectonic plates on the Pacific Ring of Fire, making it the most volcanically active country on Earth and one of the most geologically hazardous.

✨ AI Insight

Indonesia's dominance in the number of active volcanoes, with 139, is attributed to its strategic location along the Pacific Ring of Fire, where tectonic plates converge. Japan, with 111 active volcanoes, also experiences significant volcanic activity, reflecting its own tectonic complexities. The United States, with 65 active volcanoes, shows a notable gap from the top two countries, indicating a less volcanically active landscape despite its vast size. Countries like Chile (36) and Iceland (33) further illustrate how volcanic activity is often concentrated in specific geological hotspots. This trend suggests that tectonic activity plays a crucial role in determining volcanic presence, with certain regions being more prone to eruptions than others.
