Extensions to the WARN Associator, Integrating Magnitude Estimates based on Parameters from Unbiased Displacements

General processing of the parameters based on observations from seismic data alone in the associator module will not change. P-wave detection times from a minimum of four stations will provide epicentre and origin time estimates, TauP and seismic Pd reports provide initial magnitude estimates as described in Rosenberger, 2014. Joint processing of GNSS Precise Point Positioning (PPP) and accelerometer data by means of a Kalman filter was described in Rosenberger et al., 2017.
