It is a pivotal moment for arms control as many countries seek to prevent the proliferation of nuclear weapons. Join Dr. Richards for a discussion on the use of seismological methods to detect, identify, locate, and determine the size of underground nuclear explosions, and the successes and difficulties of taking this objective technical information into a charged political arena where there are deep divides on the issues of arms control.

Richards is one of the seismologists from the Lamont-Doherty Earth Observatory responsible for developing the methods used to distinguish between earthquakes and explosions.
