Where Is the Most Active Plate Boundary?

The most active plate boundary is in the Pacific Ocean basin. Several tectonic plates collide in this area, which is known as the Ring of Fire due to the high number of volcanoes, earthquakes, deep sea trenches and other seismic activities occurring on its rim.

The Ring of Fire borders four of the world's continents and is over 40,000 kilometers long. Despite the dangers of living in this region, millions of people call the areas along the Ring of Fire home, not least because of its rich farmland created by volcanic activity. Subduction of one plate under another creates a region of intense geological pressure that manifests itself in some of the most well-known faults and volcanoes around the globe.
