Between 1900 to 1918, the yearly average number of major quakes was 12. Since 2000, this number has risen to 243 / year.
I mean, of course we know more precisely where seismic fault lines are situated, better understand how strains and pressure are released and we have placed more seismographs around the world … But all of this cannot explain this nearly 2,000% increase in major quakes since 1900!
