Looking at the above summary, it is plainly obvious that overall, earthquake activity was on a gradual decline in the decades prior to 1990 but then unexpectedly, in the year 1991, some kind of 'tipping point' was reached and the number and intensity of subsequent earthquakes in all magnitude ranges began a steady and statistically significant increase.
Amalgamating all the data from the 3 magnitude ranges still shows a consistent and undeniable trend of increasing earthquake activity as is obvious in the overall increase of 38%.
So, can we conclude that the 'feelings' and 'impressions' that many ATS members have regarding significant increases in earthquake activity is justified ?
From the above analysis, it appears that we can conclude that there is indeed strong justification for such a belief.
PREDICTION
Based on the observed trends, it is more than likely that earthquake activity will continue to increase over time and that based on the above clearly observed trends, the greater proportion of future major earthquake events will be seen to occur primarily within the 6.0 to 6.9 magnitude range. However, it would also appear that we will be seeing increasing numbers of events also occurring within the 7.0 to 7.9 and 8.0 and higher magnitude ranges, compared to what were observed to have happened in past decades.
A magnitude 7.1 earthquake has struck the Solomon Islands, according to the United States Geological Survey.
The quake struck at 9.40pm and was situated 211km southeast of the Solomon Islands capital Honiara at a depth of 52km
No tsunami warning has been issued.

Anyone find it weird that it seems these big earthquakes always hit on a weekend?

I also notice that your ONLY explanation for the significant 800+ increase in magnitude 6.0 events post 1990 is by falling back on the 'we have more monitoring stations available now' ... so no other explanation should be considered as far as YOU are concerned ?

I was not aware that I had stated that there was no increase at any time, nor offered any explanation for why there is an increase in the numbers. Indeed if you looked at one of my links I agreed that there had apparently been an increase even though the USGS says not. There appears to have been a change with 6.0-6.9 going up and 7.0-7.9 going down. What I stated, and I stand by that still, is that the statistical basis on which you arrived at the 40% figure was wrong.
My apologies for derailing this thread. I will not post on this matter again.

OK, have you accounted for the change from Richter to MMS?
