The build-up of strains and stresses along earthquake fault lines has been used to try to predict earthquakes. It's measured by such scientific equipment as creepmeters, global positioning systems, laser light, magnetometers, and strainmeters that coordinate the use of the seismometer and the seismograph. The measures warn of the presence of underground vibrations, the movement of the earth's soil and crust, the modifications to magnetic field activity, and the disruption of light beam transmissions that are part of the earthquake experience.

Electronically records movements in the earth's crust and is used to monitor and predict earthquakes.
Radon is the gas that can [or cannot!] be used to predict earthquakes. Its levels noticeably may rise in basements and wells. That's because of the air and water escape routes that may form in soil 6-24 hours before an earthquake.
The strainmeter, by which its seismometer component detects the vibrations or shock waves that its seismograph records, is the scientific instrument that's used to predict and measure earthquakes.
