A New Culprit?

The earthquake that hit Nepal is hardly news anymore. The 7.8 magnitude quake on April 25 caused enormous damage and even killed 19 on Mount Everest. If that wasn’t enough, the 6.3 magnitude aftershock the following day just rubs salt on the wound. Does anyone recall how earthquakes happen? The earth underground is made up of tectonic plates, which are like chunks of rock pressed and held together. When rocks slip past each other violently, break, or somehow make a jerky movement, the earth aboveground feels the tremors of those plates suddenly setting into a new place.

Seems like everything underground is out of our control, doesn’t it? The most we do to the earth is drill it and no one seems to think those can cause an earthquake. Maybe not drilling, but Dr. Vivek Kumar Srivastava claims that global warming can cause an earthquake and undoubtedly has caused the one in Nepal. But how does heat in the atmosphere affect the earth beneath us? Well, it’s a chain reaction in this case. With the global temperature rising, ice and permafrost in the Arctic melts and raises sea levels. And perhaps a few centimeters of extra water wouldn’t be too bad, but sea levels have been on the rise for a while and are projected to rise by another 1 or 2 meters by 2100. Of course, coastal cities will be hit hardest, but this also means that there will be an extra 1 or 2 meters of water weight sitting all over the globe, adding much extra weight on the earth’s crust. Higher pressure on the earth’s crust causes the greater stress between the tectonic plates beneath us and therefore jerks much more violently into place.

The connection seems plausible, and of course no one is pointing fingers. But will we be in the near future? It’s been repeated over and over again that humans are the greatest cause of global warming and that we would come to regret our inaction gravely in the future. But could this be that future? Collapsing food chains, heat waves, rising seas, we’re observing and hearing about them all. But some people in the world might be paying for the fury of global warming right now. I’m aware that, I’m using the word “might”. Are we still going to take that chance?
