The epicenter of an earthquake is the point on the Earth's surface above the focus or hypocenter which is the point within the Earth where the rupture occurs.
As such the epicentre is the closest point to this and the seismic waves have had to travel through the smallest amount of material and so have undergone the least amount of attenuation (in this case attenuation is a reduction in amplitude of the seismic waves due to energy being lost by their movement or propagation through the Earth).
However there can be some exceptions to this and please see the related questions for more information.
Because it is the center of the earthquake. The origin.
Because that is where the quake originates.
Because it is nearest to the tectonic plates so the vibration is stronger. This is because the vibrations are closer together in the epicentre
Seismic waves.
Epicenter is used in the field of earth quakes. Epicenter means the spot where the earth quake occured or where the effects were felt the strongest
at the epicenter
2 miles southwest or southeast of Chino Hills in Southern California, was felt over a very, very large area.

the epicenter is where the waves will be felt the strongest, because they are most concentrated. How much they are felt also depends on how far under ground the seismic activity occurs
The origin of an earthquake underground is the focus, which is right under the epicenter which is the place above ground where an earthquake is felt.
at the epicenter
All living things have discernible vibrations. Try connecting to the vibrations of stone.
Yes, all noise is vibration from the sound waves. Deep noise can also be felt physically as vibrations.
Well it all depends wher the epicenter is. Wherever that is the earthquake will be the strongest but still beable to be felt in other areas.

Just parts. Earthquakes are centered at a specific place on a fault line called an epicenter but will radiate miles from the epicenter like water rippling from a rock being tossed in. From what I learned just today from reading about the Mineral, VA earthquake that was felt on the east coast, the earth's crust on that part of the country is not jagged like it is in the west. So when the quake hit, there was nothing to contain the vibrations to a small area. Instead, the quake was able to spread across 22 states. With the jagged crust on the west, probably because of the multitude of fault lines, quakes are not felt too far from the epicenter like today's east coast quake. Fortunately for us, a quake in San Francisco is not felt in Los Angeles and vice versa.
All other factors being equal, the seismic waves will be felt most strongly at or near to the epicentre of the earthquake.

A pulse can be felt where an artery crosses a bone. The main areas where the strongest pulse may be felt are the carotid artery in the neck, the brachial artery in the crook of the arm and the radial artery in the inner wrist.
