Imagine a landslide so massive it triggered a 650-foot mega-tsunami in a remote Greenland fjord—and the aftershocks made the whole Earth vibrate for nine days! Satellites and seismometers only pieced it together after the fact. Turns out, climate change is making these icy landscapes way more unstable. The craziest part? The wave got trapped, bouncing back and forth like a giant bathtub slosh, and scientists could literally see and feel it from space. Wild climate era preview, right? #Science #Greenland #MegaTsunami
