2 days ago · The focus is point inside the earth where the earthquake started, sometimes called the hypocenter, and the point on the surface of the earth directly above the focus is called the epicenter. There are two ways by which we can measure the strength of an earthquake: magnitude and intensity.

Apr 11, 2015 · Learn the difference between focus and epicenter of an earthquake, and how they affect the waves and the surface. The focus is the point where the earthquake occurs, while the epicenter is the point on the surface directly above the focus.
Earthquakes originate at a point called the focus (plural foci). From this point, energy travels outward in different types of waves. The place on the Earth’s surface directly above the focus is called the epicenter (Figure 13.2).
The epicenter is the point on the Earth's surface directly above the focus, whereas the focus is the actual location beneath the Earth's surface where the earthquake originates. One key difference between the two is their observability.
The focus is the place inside Earth’s crust where an earthquake originates. The point on the Earth’s surface directly above the focus is the epicenter. When energy is released at the focus, seismic waves travel outward from that point in all directions.
The focus, also called a hypocenter of an earthquake, is the point of initial breaking or rupturing where the displacement of rocks occurs. The focus is always at some depth below the ground surface in the crust, and not at the surface.
