You could certainly engineer it to make it work but keep in mind you'd need many many galaxies worth of material. Something like a Dyson sphere would need a few planets worth of material so they become less probable on those grounds alone.

Earthquakes are pretty localized events. People don't realize how big Japan actually is. It's as long as the entire east coast of the US. There's no way they'd have enough earthquakes to do anything like OP described. Imagine the entire east coast of the US being shut down by earthquakes, ain't going to happen.

It is an example to demonstrate how much mass is needed to accomplish even a small scale version of what their talking about. It's an analogy.
