The majority of earthquake epicenters and volcanoes around the world are located along the boundaries of tectonic plates. These plate boundaries are zones of intense geological activity where plates collide, pull apart, or slide past each other, causing both earthquakes and volcanic eruptions. This pattern is especially evident in the "Ring of Fire," a horseshoe-shaped region around the Pacific Ocean where most of the world's earthquakes and volcanoes occur
. Earthquakes can happen along all types of plate boundaries, including convergent, divergent, and transform boundaries, but volcanoes primarily occur at constructive (divergent) and destructive (convergent) plate margins
. Thus, while earthquake epicenters are distributed along all plate boundaries, volcanoes are generally concentrated where magma can rise to the surface, such as subduction zones and mid-ocean ridges. In summary, both earthquake epicenters and volcanoes are closely associated with tectonic plate boundaries, but volcanoes are more specifically found at convergent and divergent boundaries, whereas earthquakes occur along all types of plate boundaries
