WebEarthquake - Earthquake magnitude Britannica Earthquake magnitude is a measure of the “size,” or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs. (The types and nature of these waves are described in the section Seismic waves.) Webepicentre, point on the surface of the Earth that is directly above the underground point (called the focus) where fault rupture commences, producing an earthquake. The effects of the earthquake may not be most severe in the vicinity of the epicentre. The epicentre can be located by computing arcs from each of three or more seismic observatories, with the …
