I think that although (estimated) magnitude is helpful, Japan's system also calculates the (estimated) intensity from the earthquake for your local area. Not always correct (but this tends to be rare), but usually within +/-1 of the Shindo scale (which is their local intensity scaling). Seems that ShakeAlert doesn't compute (yet, hopefully) the estimated intensity in your area.
