Reference Material:
So faults are breaks in the earth crust, we can identify them because of the discontinuity in the structure within the earth crust across fault. And earthquake occur on these faults, so vary processes by which these faults moves to a large extent is due to earthquakes. So we have a fault plane and the earthquake is so focus on this fault plane and the earthquake starts at the particular point on the fault plane and we call that the focus of the earthquake. The rock prorogate out from that point on the rupture plain to cover the entire fault plane. The rupture is in that particular earthquake. We talked about the epicenter of the earthquake a lot. The epicenter is just the surface projection of the focus of the earthquake. So if you wanted to looking at map view where the earthquake was located we would be able to look that into the earth. We would see the focus down some depth in the earth or the epicenter just a point vertically above that focus at the surface of the earth. So this is the focus between the faults and the earthquakes.
Sample Answer:
Faults are breaks in the earth crust, constructing a fault plane. An earthquake starts at a particular point on the fault plane, called the focus of the earthquake. The rocks propagate out from the focus, creating the rupture that is in that particular earthquake. The epicenter is a point vertically above the focus on the earth’s surface. So, this is the relationship between the faults and the earthquakes.
