On the east central Pacific Rise of 15:15:43 on this the 10/30, USGS 
indicates the quake was Ms .5.7

Using WinSDR and Winquake; I calculated the P as 5.2 seconds on a AS-1 

The Mb calculated out as 4.1 The magnitude correction I had chosen was 
-1.8. Is my next step to chose a positive number less than one.
