I was studying EQs in 2013 and pulled some of the USGS datasets for graphing also. Wasn't looking at depth, though. Didn't keep the data set, just the graphs resulting from the analysis. At the time I was trying to determine if there was a trend of EQs increasing in quantity and/or magnitude.
Question: Do you believe the declared EQ depth, or can it be explained away as an artifact of the way the data gets interpreted? For me that is an open question.
