Answer:
Focus
Step-by-step explanation:
The focus is the point from which the earthquake originates from. The epicenter is the point above the focus. A fault line is a place where rocks have slid past each other and are not connected. They are found where two tectonic plates meet. While two of these plates sliding along their fault line can cause an earthquake, it is not always the earthquake's point of origin. And finally, a Tsunami is a large wave that is caused by the result of an earthquake.
