Earthquake magnitude vs acceleration
WebThe most direct description of an earthquake motion in time domain is provided by accelerograms that are recorded by instruments called Strong Motion Accelerographs. The accelerograph records three orthogonal components of ground acceleration at a certain location. The peak ground acceleration, duration, and frequency content of earthquake
