Nothing is going on that has not gone on just this way for millions of years.
The Earth's magnetic field fluctuates (and this has been directly tracked sine the 1400s, and there is archaeological evidence going back thousands more years, and seafloor stripes going back 200 million years).
The magnetic field is definitely in decline - this has been knwon for hundreds of years.
It is probably heading into another reversal (this happens every few hundred thousand years).
Again - nothing new.
Some small earthquakes are definitely related to fracking, but Sendai was natural, Aceh was natural, Concepsion was natural...all the big ones were natural...
Nothing here to spend any time worrying about or arguing.
