Calm down, for God's sake.

Just looking for some honest debate given the best information at our disposal. The Centennial Catalog, particularly two charts included therin, is the best data I could find to base a discussion on and you STILL haven't commented on it. It's frustrating but it may just be my fault. My patience wears thin at times and I apologize for any sourness in my disposition.

That's OK, FRiend. I try to rely on accurate data on everything I post here . And my source, as well as yours, did say it was based on USGS data. Precious little info on any of these official government websites is presented in a straight forward, easy to read and understand fashion, even when the info is intended for the public (government seems to always have their heads up their butts when it comes to communicating). However, I do now see the chart you posted on that USGS link you provided (Centennial report, page 6 on the pdf).

I also found the following which similarly supports what you said:

"We continue to be asked by many people throughout the world if earthquakes are on the increase. Although it may seem that we are having more earthquakes, earthquakes of magnitude 7.0 or greater have remained fairly constant."

In any case, I was really (initially) referring to what seems to me to be an increase in large quake activity in and around the Indonesia area over the past few decades. I kind of mixed up the two two things with that chart on activity worldwide.
