To locate the epicenter of an earthquake, you must have SEISMOGRAMS from at least three seismic stations.
Scientists use seismographs to measure thousands of earthquakes, large and small, every year. Some seismographs can detect ground movements as small as one hundred-millionth of a centimeter. The recording produced by a seismograph is called seismogram. By studying seismograms, scientist can determine the locations and strengths of earthquakes.
Seismologists use the difference in arrival times of seismic waves at different monitoring stations to determine when an earthquake started. By analyzing this data, they can pinpoint the origin time of the earthquake. Additionally, seismologists use advanced computer algorithms and technology to help refine the accuracy of the timing.
It is important to do this because then people will know how much damage it REALLY caused, if it could've triggered tsunamis, how big it is, the epicenters' magnitude, and where it started. They would also know possible ways that it happened, if it is linked to other earthquakes, and what it could cause in the future. That is why it is important to locate the epicenter.
its directly below the epicenter
The greatest shaking near an earthquake's epicenter occurs because the seismic waves have less distance to travel, resulting in less attenuation and energy loss. This leads to stronger shaking at locations closer to the source of the earthquake.

An earthquake.
in america
Because of the tsunami that started at Alaska.... which made the earthquake in Hati
An earthquake is usually started by two or more tectonic plates grinding together and thrusting up earth and rock.:)
The earthquake started 16 miles west from Port-au-Prince.
the danger spot during an earthquake is at the epicenter wich is the place right above were the earthquake was originaly started.
Caused by natural forces!
the underwater earthquake started it.
an earthquake (magnitude of 9.0).
The earthquake in Japan started on March 11th, 2011 at 9:00 P.M. PST.
