Scientists are using thunderquakes to see what’s hidden underground…
When lightning strikes, it heats up the air around it, creating a shockwave that you hear as thunder. When that energy hits the ground, some of it turns into seismic ripples in the dirt and rock…
These ripples penetrate the surface, so to listen to them, scientists used buried internet cables. By recording lots of thunderquake ripples, they can X-ray the earth!
And they’re trying to use this idea to see below the surface of other planets. To see more, subscribe!
