Calm down, for God's sake. What are you getting so worked up for?
I’m always a bit amused by those who appeal to statistical error, claiming the reduced numbers of >7.0 earthquakes in prior decades/centuries were due partly to the recent numerical increase in seismometers.
It is academia at its most ignorant failure to identify their statistics with the things being measured.
If we accepted that logic, then people in remote regions just didn’t have the resources to perceive >7.0 earthquakes, or perhaps forgot about them. Such an absurd notion disproves their assertions prima facie.
Perhaps in very remote regions where nobody ventured within a 1000 miles or traversed the vicinity, and neither were there geologists to have looked at geologic records, some might have been missed,...but even then that is based upon conjecture as well.
