Earthquakes: Inside The Earth Don't Eat the Earth's CRUST

Earth's Crust




The Earth's outermost surface is called the crust. The crust is typically about 25 miles thick beneath continents, and about 6.5 miles thick beneath oceans. The crust is relatively light and brittle. Most earthquakes occur within the crust. The crust in this image is much smaller in the real earth!
