Where does earthquakes and volcanic eruption occur in?

Earthquakes and volcanic eruptions primarily occur along tectonic plate boundaries, where the Earth's plates interact. Most seismic activity is found at convergent boundaries (where plates collide), divergent boundaries (where plates move apart), and transform boundaries (where plates slide past each other). Additionally, volcanic eruptions often occur in subduction zones and along mid-ocean ridges, where magma rises to the surface. Regions like the Pacific Ring of Fire are particularly active due to these geological processes.
