Earthquake magnitudes are determined by measuring the amplitudes of seismic waves. The amplitude is the height of the wave relative to the baseline (Figure 12.13). Wave amplitude depends on the amount of energy carried by the wave. The amplitudes of seismic waves reflect the amount of energy released by earthquakes.Magnitude scales, like the moment magnitude, measure the size of the earthquake at its source. An earthquake has one magnitude. The magnitude does not depend on where the measurement is made. Often, several slightly different magnitudes are reported for an earthquake. This happens because the relation between the seismic measurements and …Biography. 2010-2013,Kyoto University. 2013-2016, Earthquake Research Institute, The University of Tokyo. 2016~now, China University of [email protected] of Earthquakes using large scale data and GSGL computer graphics - Compare · alexaheidgerken/EarthQuake-SimulatorBroadband (0-5 Hz) fully deterministic three-dimensional ground motion simulations of a magnitude 7.0 Hayward Fault earthquake: comparison with empirical ground motion models and 3D path and site effects from source normalized intensities, Seismo.
