Climate causes the earth to move. An international team of researchers discovered that more rainfall in India made the Indian tectonic plate speed up by factor of 20 percent.

“The significance of this finding lies in recognizing for the first time that long-term climate changes have the potential to act as a force and influence the motion of tectonic plates,” Giampiero Iaffaldano, researcher at Australian National University, told Cosmos.

The scientists studied monsoon records in India for the past 10 million years and linked it to the motion of the tectonic plates, reports the Sydney Morning Herald. Of course, the seismic shifts didn’t happen overnight, it took millions of years to change the direction of plates. Still, tectonic plates move very slowly…about the speed at which your fingernails grow, explained Iaffaldano.

The study was published in the journal Earth and Planetary Science Letters.

All this study showed was that plate movement occurs on a feedback mechanism: It’s not all one-sided after all. In India, more rain made the plates move faster. But remember, the change happened slowly - at about one centimeter per year.

You might be thinking you already knew this, but this finding is counter-intuitive. First of all, we knew that plate movement can create new mountains and affect ocean basins. But now, researchers are finding out that it can work the other way too. Climate change can cause seismic shifts - and possibly make some regions more likely to have large earthquakes than others.
