I have noticed whenever there is a big earthquake one place

that there will often be earthquakes the same day or next day or so all over the earth for years now. So, the research in a previous article makes complete sense to me that earthquakes on one side of the planet often can cause earthquakes somewhere else on the planet too.

To me, it all makes logical sense if I think of the world as one place as it is. When you take a hard substance (the plates) and move them in relation to each other it makes complete sense that for every action there might be an equal reaction somewhere or many somewhere elses on the planet as all the plates try to adjust to the movements somewhere else.
