Hi,
Without using machines (complicated machines to be exact) which get the information using echo (like a sonar of a fishing ship getting location of ships) it is impossible to do it.
The machine itself runs based on a set of physics and mathematics formula.
The interesting fact is that each country has its own department to take care the matter of earthquake. In U.S., it is the United States Geological Survey.
However, more information about this as well as to get the latest information about incoming earthquake, you can always check the links that I post below this. :)
Hope this helps
Kind regard,
Ryonn

USGS is continually predicting earthquakes. For example, the Hayward Fault I live near is predicted to have a 6.9 Richter earthquake in the next 20 years. But that's not very useful information save to ensure my house is earthquake hardened and to have an earthquake response plan.
There are quacks who claim they can predict ensuing earthquakes with but a few minutes or hours of warning time. But, if you check their predictions, they are so ambiguous you can show their predictions were true for just about any quake anywhere and any time. In other words, they are not real predictions at all; just carefully worded assertions that could means just about anything.
The USGS predictions are based primarily on regression analysis. This is a statistical technique that examines data and draws out trend lines from those data. The data in this case are past earthquakes, both major and minor.
These data are collected by remote seismic readers, which send the shaking data back to USGS sponsored shops where the data are analyzed and trend lines are developed. There are a lot of seismically active areas in California; so lots of data are collected daily.

With every day pass, our country is getting into more and more trouble. The inflation, unemployment and falling value of dollar are the main concern for our Government but authorities are just sleeping, they don’t want to face the fact. Media is also involve in it, they are force to stop showing the real economic situation to the people. I start getting more concern about my future as well as my family after watching the response of our Government for the people that affected by hurricane Katrina.
According to recent studies made by World Bank, the coming crisis will be far worse than initially predicted. So if you're already preparing for the crisis (or haven't started yet) make sure you watch this video at http://www.familysurvival.tv and discover the 4 BIG issues you'll have to deal with when the crisis hits, and how to solve them fast (before the disaster strikes your town!) without spending $1,000s on overrated items and useless survival books.

particular. Jens is actual. The Richter scale is predicated on the recorded floor action on a particular form of seismometer and the gap far flung from the earthquake. that's an previous scale that's perhaps not used anymore, in spite of the undeniable fact that that's instructive in helping human beings see how intensity of an earthquake can exchange over distance. Given 2 of the three products of tips (amplitude, distance, significance), you will discover the third by installation a line however the two products of tips you do understand on the nomograph that Jens provided the hyperlink to. Make a mark at significance 5, yet another mark at 200km, connect them in a line and notice the place that line is going in the process the amplitude line and there is your amplitude.

I don't think so.
