This section examines earthquakes as the result of sudden movement within Earth’s crust. It explains how earthquakes occur, how they are related to plate tectonics, and how their location and magnitude are measured. The section also considers the effects and hazards associated with earthquakes and why their impacts can vary considerably from one event to another.
