Map showing stations with picks used to locate the earthquake. Stations with picks that have a zero weight in the solution are shown as small grey circles. Those with a higher weight are shown as larger circles. The quake is shown by the largest circle.

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) * Mw(mB)) / (2 + (0.4 *
number_of_stations(Mw(mB)) - 1))
Where MLv is local magnitude calculated on the vertical component and Mw(mB) is a Mw
estimation
based of mB by Bormann and Saul (2008).
