## Caption

A tsunami on a truly global, continent-overwhelming scale would not happen from earthquakes, storms, or volcanic eruptions alone. Events like that would require an extraordinary, external force — such as a large planetary body colliding with Earth.

Here’s the science behind it:
	•	Earthquakes displace sections of the seafloor, but even the largest ones only move limited areas. The ocean simply can’t be pushed hard enough, over a wide enough region, to create a planet-spanning wave.
	•	Underwater landslides and volcanoes can cause dangerous regional tsunamis, but their energy dissipates rapidly as waves spread.
	•	Storm surges are driven by wind and pressure, not deep-water displacement, so they lack the vertical force needed for mega-tsunamis.

To generate a wave capable of flooding multiple continents at once, you’d need:
	•	Instant, massive ocean displacement
	•	Energy far beyond Earth’s internal processes
	•	A trigger large enough to affect the entire planet at the same moment

A planetary or large asteroid impact fits those requirements. The kinetic energy released would displace vast volumes of ocean water simultaneously, sending shockwaves through the planet and producing tsunamis on a scale far beyond anything Earth’s geology can create on its own.

In short:
🌍 Earth can make tsunamis — but only space can make one like that.
