The majority of earthquake epicenters and volcanoes are both predominantly located along tectonic plate boundaries. These areas are zones of intense geological activity where Earth's plates interact, causing both seismic activity (earthquakes) and volcanic eruptions. A prime example is the Pacific Ring of Fire, where over 80% of large earthquakes and many active volcanoes occur due to subduction processes at plate boundaries. This overlap occurs because tectonic plate movements create the conditions for both earthquakes and volcanic activity. Earthquakes mainly happen where plates grind, collide, or pull apart, while volcanoes form primarily at convergent boundaries (where subduction occurs) and divergent boundaries (where plates separate), allowing magma to reach the surface. Thus, the locations of the majority of earthquake epicenters and volcanoes closely correspond, both clustering along Earth's tectonic plate edges rather than being randomly scattered across the globe.
