Imagine drilling 7km under the sea just to grab a piece of the fault that caused the 2011 Japan mega-earthquake and tsunami. That’s exactly what a team of 60 scientists did, pulling up deep-sea cores that could reveal how these monster quakes get triggered. They even installed a high-tech observatory to watch the fault in real time. This could totally change how we predict and prepare for tsunamis worldwide. Wild, right? #Science #earthquake #tsunami
