The S-P time method is perhaps the simplest method seismologists use to find an earthquake's epicenter. +++ No it's not. That finds its Focus. The Epicentre is the point of maximum movement on the land surface above the slip itself.
No. There is no way of predicting earthquakes and it is unlikely that a method to do so will be developed in the near future.
Short term predictions of earthquake behaviour or even earthquake predictions in general have not occured yet. Many even question if earthquakes will ever be able to be predicted. Even the earthquakes that have supposedly been predicted correctly have controversy behind the method
There are 2 ways.Richter scale. This is an objective method, and is a scale of 1-10, each 0.1 increase in size is a 10 fold increase in power. (it is only possible, even with a mega-thrust quake to reach 9 on the Richter scale). This is the most accurate and commonly used scaleMercalli Scale. This is a subjective scale, and the reading is based on the damage done by the earthquake. It is a scale of roman numerals between 1-14.

The maximum intensity is at the epicenter. It is how the scientists calculate the epicenter.
magnitude
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.

It takes three seismographs to locate an earthquake. Scientists use a method called triangulation to determine exactly where the earthquake occurred. If a circle is drawn on a map around three different seismographs where the radius of each is the distance from that station to the earthquake, the intersection of those three circles is the epicenter.

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
