We present a procedure for rapid determination of an earthquake moment magnitude, Mwp, at regional distances from the P‐wave first arrivals based on Tsuboi et al. (1995, 1999) and Kanjo et al. (2006). We apply an automated window‐length selection and use a variable P‐wave velocity instead of a constant value to make a better estimation for Mwp magnitude. This procedure is applied to 46 earthquakes with magnitude (Mw) greater than 4.8, which have been recorded and analyzed for Global Centroid Moment Tensor (Global CMT; the Global Centroid Moment Tensor Project...
