This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers. Most faults produce repeated displacements …

It was developed in 1931 by the American seismologists Harry Wood and Frank Neumann. An earthquake prediction must define 3 elements: 1) the date and time, 2) the location, and 3) the magnitude. Yes, some people say they can predict earthquakes, but here are the reasons why their statements are false: They are not based on scientific evidence, and earthquakes are part of a scientific process.
