Here's What Earthquakes Look Like From Inside the Earth | National Geographic

[Music] The question came up of whether you could hear earthquakes, and I said, “I don't think so, but we could take the data and speed it up and listen to the whole planet ring after an [Music] earthquake.”

The seismo show is an ongoing project in which we use earthquakes and the waves that they emit to teach people about the planet.

All right, now we're going to go to the T Hoku earthquake. So, in the show, we have a magnitude s, you know, and that energy dies out in about a day. Whereas a magnitude 9 or higher, the Earth is ringing for about 3 months.

With every passage of a seismic wave through the Earth, we get a little more information about the structure of the [Music] inside. We're always playing with time, so we always say this is seven years of earthquakes.

You're going to hear it in a minute. That means just the list of earthquakes, where they were, and how big they were, and how deep they were.

We want to give people a sense of how small we are, how short our lifetimes are, and hopefully they walk out of that planetarium with a very altered sense of their lives and our roles on [Music] Earth.
