WebGeophysics. Earthquake energy is dispersed in waves from the hypocentre, causing ground movement omnidirectionally but typically modelled horizontally (in two directions) and vertically.PGA records the acceleration (rate of change of speed) of these movements, while peak ground velocity is the greatest speed (rate of movement) reached by the ground, … WebApr 12, 2024 · GeoNet combines magnitudes into a summary magnitude, M, which consists of a weighted average of the individual magnitudes and attempts to be a best possible compromise between all magnitudes for a range of earthquake sizes.Summary magnitude for GeoNet is then defined as: M = (2 * MLv + (0.4 * number_of stations(Mw(mB)) - 1) * …
