Seismic stabilizer
A seismic stabilizer was an orbital component of a weather control system, responsible for calming seismic activity relative to impacting the weather.

Caldos had a seismic stabilizer in orbit. In 2370, the Caldos colony experienced infrequent tremors, which Lt. Commander Data was able to connect to a  fluctuation in the weather control system. ()
