Want this question answered?
No, the greatest intensity of an earthquake is not always found at the epicenter. The intensity of an earthquake can vary at different locations depending on the distance from the epicenter, the depth of the earthquake, and the local geological conditions. In some cases, the intensity may be greater at locations further away from the epicenter due to the way seismic waves propagate.
No, though they can narrow it down to two possible locations.

it is directly above the focus
The energy released by an earthquake is measured using a seismometer. The amplitude of the seismic waves recorded by a seismometer are in-turn plugged into an equation that gives a value on the magnitude scale.

The simplified answer is that it works much in the same way you would determine the source of a sound (which is also in waves). Multiple measurements of the intensity are taken from different locations are used to triangulate an earthquake.

No. Without a 3rd peice of data from another station, there will always be 2 different possible locations of the epicenter. You must have 3 seismographs to collect the data.
The epicenter refers to the point on the earth's surface above the focus of an earthquake. Geologists determine the epicenter with the use of 3 seismographs. This method is called triangulation.
You would need at least three different seismometer locations to triangulate an earthquake's location.
Then you would end up with 2 possible locations for the epicenter. You need a 3rd station to confirm the actual location.

They first collect several seismogram tracings of the same earthquake from different locations. Then the seismograms are placed on a time distance graph. The seismogram tracing of the first p wave is lined up with the p wave time distance curve. The difference from each station from the earth quake can be found by reading the horizontal axis. After finding out the distance, a seismologist can locate an earthquake's epicenter.
The seismograph was not invented until the later part of the nineteenth century. So the magnitude and exact locations of the earthquake(s) that occurred on the New Madrid Fault (or Reelfoot Rift ) in 1811 and 1812 are not known. Evidence from "sand blows" indicate the epicenter of one of the larger ones that occurred on February 7 of 1812, was near the town of New Madrid, Mo.

The first step in this method is to collect several seismograms of the same earthquake from different locations. Then, the seismograms are placed on a time-distance graph. The seismogram tracing of the first P wave is lined up with the P-wave time-distance curve, and the tracing of the first S wave is lined up with the S-wave curve.The distance of each station from the earthquake can be found by reading the horizontal axis. After finding out the distances, a seismologist can locate an earthquake's epicenter.-New Boyz
