Magnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location. Intensity is determined from effects on people, human structures, and the natural environment.
mechanical vibrations such as waves observed on the surface of water have been looked upon as an oddity since time immemorial, since the way that the waves are actually formed has been a mystery to most people. today, however, from work done by past researchers, there is a vast practical knowledge accumulated concerning mechanical vibrations, also known as wave phenomena
