Earthquakes were seismic radiation generated through the displacement of land. Shifts in tectonic plates relative to each other caused a huge release of energy that spread over great distances, causing quakes to spread across a great area.
However, there was a person who sought to harness this mechanism and use it as the source of their power.
Except in reverse.
Seismic radiation would diverge from the epicenter, which was generally located at the site of displacement. However, some discovered that if the diverging seismic radiation from the epicenter were to instead converge at the same epicenter, a reverse displacement would occur.
They were reversible phenomena.
This gave rise to the niche art of displacing land by generating converging seismic radiation with one's body.
