The term “Ring of Fire” highlights the intense heat and light produced by the hundreds of active volcanoes lining the Pacific basin. It is not a single circular structure but a series of interconnected plate boundaries, including subduction zones and transform faults. This belt defines the geography of countries like Indonesia, the Philippines, Japan, Canada and Chile. The high activity level is due to the rapid movement of the Pacific Plate, which creates constant friction and melting as it interacts with the surrounding Eurasian, North American and Indo-Australian plates.
