Do nuclear bombs cause earthquakes? (Gods wrath? think again!) The pressure wave from an underground explosion will propagate through the ground and cause a minor earthquake. Theory suggests that a nuclear explosion could trigger fault rupture and cause a major quake at distances within a few tens of kilometers from the shot point. Nuclear bomb testing has doubled the earthquake rate. - Gary Whiteford, Professor of Geography, University of New Brunswick Abnormal meteorological phenomena, earthquakes and fluctuations of the earths axis are related in a direct cause-and-effect to testing of nuclear devices. - Shigeyoshi Matsumae, President Tokai University Yoshio Kato, Department of Aerospace Science what about nuclear explosions? Well, they indeed cause earthquakes—that is, they are earthquakes, releases of energy that are felt as shaking and recorded by seismographs around the world. But not even the largest bomb test has ever induced a natural earthquake. Like natural earthquakes, underground nuclear tests have aftershocks. We know this because they act like aftershocks: they are smaller than the main event, cluster around its location, and decrease as time passes. Also, the largest bomb tests have the same magnitude as moderate earthquakes, and their aftershocks are smaller by a full unit of magnitude (that is, they obey Båths law), just like natural aftershocks.
