The Ring of Fire is the geographical area known for its significant volcanic activity. This zone encircles the edges of the Pacific Ocean, characterized by frequent earthquakes and numerous active volcanoes. Countries that lie along the Ring of Fire include Japan, Indonesia, the Philippines, and parts of North and South America. The movement of tectonic plates in this region results in the geological phenomena that make it one of the most seismically active areas in the world, influencing the ecology and human activities.
