|
|
|
The seismic station closest to the earthquake
|
|
|
The place where the greatest damage occurs
|
|
|
The point on the surface directly above the focus
|
Detailed explanation-1: -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.
Detailed explanation-2: -The spot underground where the rock first breaks is called the focus, or hypocenter of the earthquake. The place right above the focus (at the ground surface) is called the epicenter of the earthquake. Cutaway view of the reverse fault. The earthquake starts at the focus, with slip continuing along the fault.
Detailed explanation-3: -Epicenter is the point on the surface of the earth vertically above the place of origin (hypocentre) of an eartquake. It is at the epicenter that the worst effects of the earthquake are felt.
Detailed explanation-4: -Hypocenter or the focus is the point where an earthquake or an underground explosion originates. Epicenter is the point that is directly above the focus on the surface of the earth. During earthquakes, most of the time it is the epicenter that encounters greatest damage.
Detailed explanation-5: -2) Epicenter is the point on the surface nearest to the focus of an earthquake.
