where do earthquakes mostly occur
Earthquakes occur most frequently around the edges of tectonic plates, especially where two plates are either colliding or sliding past one another. The most active earthquake zones in the world are in areas around the edges of the Pacific oceanic plate, such as California, Indonesia, Japan and New Zealand.
Earthquakes occur most often along the edges of oceanic and continental plates. Oceanic plates are the large pieces of the Earth's crust that are located beneath the oceans. Continental plates hold the Earth's large land masses.
