**Step-by-Step Solution:** 1. **Definition of Epicenter**: The epicenter of an earthquake is defined as the point on the Earth's surface that is directly above the focus (or hypocenter) of the earthquake. The focus is the actual location within the Earth where the earthquake originates. 2. **Seismic Waves**: When an earthquake occurs, it generates seismic waves that travel outward in all directions from the focus. These waves are what cause the shaking and damage associated with an earthquake. 3. **Distance from the Focus**: The epicenter is the closest point on the surface to the focus of the earthquake. Since seismic waves lose energy as they travel through the Earth, the areas closest to the focus (including the epicenter) experience the strongest shaking and impact. ...
