The Ring of Fire is a horseshoe-shaped zone in the Pacific Ocean basin known for its high volcanic and seismic activity. It is home to about 75% of the world's active and dormant volcanoes, including famous ones like Mount St. Helens and Krakatoa. This area is also prone to earthquakes due to tectonic plate movements. The Ring of Fire stretches approximately 25,000 miles and includes countries such as Japan, Indonesia, and parts of the United States like California and Alaska. The intense geological activity in this region is primarily caused by the interactions of several tectonic plates, including the Pacific Plate and the North American Plate.
