How an Earthquake epicenter and magnitude is determined:
To determine magnitude of an earthquake there are many ways one could evaluate: from the cost of repairs resulting from damage, from the length of rupture of the earthquake fault, from the amount of ground shaking, etc. But determining the strength of an earthquake using these kinds of "estimators" is full of potential problems and subjectivity.
A well-known scale used to compare the strengths of earthquakes involves using the records (the seismograms) of an earthquake's shock waves. The scale, known as the Richter Magnitude Scale created by Dr. C. F. Richter. The Richter magnitude determination is based on measurements made on seisograms. Two measurements are needed: the S-P time interval and the Maximum Amplitude of the Seismic waves.

The career preparation in order to be a GEOPHYSICIST
In High School
Take plenty of math and science classes as possible, along with a computer science class. If your high school offers earth science or any other earth focused sciences take them.
You need a background in science, emphasis in math, physics, and geology. Students who major in physics have an easier time in graduate school then someone with a geology major.
Strong academic course work is important, students interested in geophysics can also benefit from obtaining first-hand experience in the field itself.If you have access to local field trips conducted by academic or government organizations, they would expose you to the sorts of things geophysicists are interested in. Student internships or summer programs with a geophysical consulting company, an academic geophysics department, or the U.S. Geological Survey would be an invaluable experience.
