Quick thought experiment… 🤔🌍 Picture a satellite watching Earth. Suddenly a colossal tsunami begins racing across the ocean. Could it cover entire countries? In reality, the numbers don’t support it. To push that much water high enough to flood large land areas, the ocean floor would have to move hundreds of metres instantly across massive distances. No known geological process on Earth can do that. Even the powerful events behind historic tsunamis only shift the seabed by a few metres. Energy spreads, friction slows waves, and gravity pulls water back down. So while tsunamis are incredibly dangerous locally, the idea of a planet-wide ocean wall just doesn’t line up with the physics of our planet. Still fascinating to imagine though. 🌊 #water #planetearth #seafloor #tectonics #research
