Final answer:
Earthquakes usually occur along fault lines where tectonic plates meet and interact.
Step-by-step explanation:
An earthquake usually occurs along fault lines, which are fractures in the Earth's crust where tectonic plates meet and interact. The sudden release of energy along these fault lines causes the ground to shake and leads to an earthquake. The most common locations for earthquakes are plate boundaries, where the movement of tectonic plates is most active. For example, the Pacific Ring of Fire, which encircles the Pacific Ocean, is known for frequent seismic activity.
