A seismic regulator was a device used to control seismic activity in a planet's crust, generally to prevent earthquakes.

Risa is equipped with seismic regulators to stop any earthquakes from occurring. In 2373, Pascal Fullerton cited the regulators as being an example of the illusion that was Risa. (DS9: "Let He Who Is Without Sin...")

Seismic regulators were being installed in a subterranean cavern under the city of San Francisco on Earth in late 2368 when a work crew discovered the severed head of Data, which had been buried there for five centuries. (TNG: "Time's Arrow")
