    I had heard about the change in the magnitude but since I monitor 4 sites 2 in the US and two not, I see the same info on all the sites. I think its due to the number of monitoring stations involved. Its like the rings on the water on a lake if you throw a stone in the water…as each ring goes further and further out it activates bells… it reminds me of when I was at the OES Offices in Sacramento at the Warning Center. If there was a quake down in N CA if you watched a few seconds the waves moved out from the shock ( stone ) and as they passed each monitoring station they would set that one off with lights some quakes would start on one end of the state and would end up setting off alarms in the opposite side of the state. With out technology so fast the information comes in before it can be verified and the web sites pick it up via wireless and post it before its been reviewed by a seismologists.
    and bells… so we have the capability to get info so quick, the USGS needed to wait till they rec’d all the data and then they would decide the magnitude of that quake based on the criteria for a quake in that area, taking into consideration the time, location and depth as well as the magnitude.

    Hope this helps and remember its only my personal opinion.
