Earthquakes

…

…When data is stored about seismic zones we find only four types of zones exist, according to plate tectonics. The first occurs under the ocean along the narrow ridges beneath the sea. The second type of zone affected by earthquakes, is from volcanoes when they erupt lava. The third type is associated with collision of oceanic, and continental plates. The final seismic zone is measured from the boundaries of continental plates alongside mountains (Spall, Henry 3).
