A method used by seismologists wherein data from three recording stations are gathered to determine the epicenter of an earthquake

• Triangulation method

• Pythagorean theorem

• Circulation method

• Square method

What is the primary method used to locate the epicenter of an earthquake?

• Triangulation

• Seismograph

• Richter Scale
