.. _global_mlr: ### MLr ### The MLr plugin is designed to use the MLv station amplitudes and provides a GNS/Geonet local magnitude (Jristau this study: - REF-). The magnitude uses a station correction term and the hypocentral distance Hard coded range are 0-20 degrees maximum distance, and 800 km max depth. Description =========== Amplitude --------- The MLr amplitude calculation is that of the Mlv amplitude computation Station Magnitude ----------------- The MLr plugin calculates the individual station local magnitude using the following formula: .. math:: //based on sed MLh magnitude: mag = \log10(waamp1) + A \times hypdistkm + B mag = log10(waampl)-log10(waamplRef) log10(waamplRef)= 0.2869 - 1.272*1e-3*(hypdistkm) -(1.493 * log10 (hypdistkm)) + (StationCorrection) // A(station) Station correction - given by module.trunk.NZ.WEL.MLR.params, A ; // Sation Correction is set to be distance dependent; // Option nomag disable the station magnitude. waampl is the amplitude produced by the MLr plugin. Hypdistkm is the distance from the sensor to the hypocenter in kilometers. Overall Event Magnitude ----------------------- The GNS/Geonet Mlr local magnitude is using the default Sc3 behaviour for the automatic network magnitudes. Hard coded range are 0-20 degrees maximum distance, and 800 km max depth.
