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.

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.

Scientists are able to predict large earthquakes to a certain extent. With the use of certain statistical methods, many earthquakes are able to be predicted.
Radon gas may or may not be used to predict an earthquake. Scientists in Chile and Italy sometimes find increased levels of radon gas in wells 6-24 hours before an earthquake. The increase is due to tiny escape routes that form during the crustal [or lithospheric or tectonic] plate activities that lead to earthquakes. Specifically, an example of a successful prediction based on radon gas levels is the warning by Gran Sasso laboratory researcher Giampaolo Giuliani of the April 7, 2009 in the region of Abruzzo.
Electronically records movements in the earth's crust and is used to monitor and predict earthquakes.
It is important for scientists to develop ways to predict earthquakes. By it they can measure when the next one would be.
Scientists have no power to control earthquakes, nor to specifically predict them, but a logical area that the earthquakes would take place is along the plates of the earths crust. (Their shifting leads to earthquakes)
