Method not used to predict earthquakes is astrology. Earthquakes are typically predicted using scientific methods such as seismology, GPS monitoring, and studying patterns of seismic activity. Astronomical events do not have a proven correlation with predicting earthquakes.
seismometers and seismographs
Scientists have attempted to predict earthquakes by monitoring the build-up of stress along fault lines, changes in groundwater levels, animal behavior, and variations in electromagnetic fields. However, predicting earthquakes with high accuracy remains a significant challenge due to the complexity of geophysical processes involved. Current focus is on improving early warning systems rather than precise prediction.

Scientists have used various methods to predict earthquakes, including monitoring seismic activity, studying fault lines, analyzing electromagnetic signals, and tracking groundwater levels. Despite these efforts, accurately predicting when and where an earthquake will occur remains a significant challenge due to the complex and unpredictable nature of the Earth's crust.
Computer Model
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.
Seismographs show vibrations, for earthquakes. Much tech is used to predict weather and find dangerous storms.
