This area is called the "Pacific Ring of Fire" because it is a horseshoe- shaped zone around the Pacific Ocean that is characterized by a high concentration of active volcanoes and frequent earthquakes. The name "Ring of Fire" stems from the prominent volcanic activity along this belt, which contains about 75-80% of the world's active volcanoes and experiences around 90% of the world's earthquakes. The region marks the boundaries where multiple tectonic plates meet and subduct under each other, leading to volcanic eruptions and seismic events. The term also reflects the historical association between volcanoes and fire, with volcanic molten rock and eruptions giving a fiery impression around the Pacific Ocean rim.
