Key Facts About the Pacific Ring of Fire
- Description: The Pacific Ring of Fire is a horseshoe-shaped zone around the Pacific Ocean known for frequent earthquakes and volcanic activity.
- Geographical Extent: It stretches approximately 40,000 km around the Pacific, following the boundaries of several major tectonic plates.
- Global Significance: It accounts for around 90% of the world's earthquakes and about 75% of its active volcanoes.
- Major Plates Involved: Includes the Pacific, Nazca, Cocos, Juan de Fuca, North American, Philippine, and Indo-Australian Plates.
- Spatial Distribution: Extends along the western coasts of North and South America, through Alaska, and across East and Southeast Asia to New Zealand.
- Countries Associated: Includes Chile, Peru, Ecuador, Colombia, Mexico, the United States, Canada, Russia, Japan, the Philippines, Indonesia, Papua New Guinea, and New Zealand.
- Cause of Volcanism and Earthquakes: Tectonic plate subduction and fault movement lead to frequent earthquakes and volcanic activity.
Colombia's Geographical and Economic Context
Colombia is uniquely positioned with coastlines on both the Pacific Ocean and the Caribbean Sea, contributing to its strategic maritime significance. It is a megadiverse country, hosting close to 10% of the planet’s biodiversity, which aligns with India's environmental and ecological goals. However, Colombia also faces challenges as a major center of coca cultivation and cocaine production, impacting global drug trafficking dynamics.
