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.
Radon (Rn)
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.
Instruments used to predict eruptions include seismometers to detect earthquake activity, gas analyzers to monitor changes in gas emissions, thermal cameras to detect changes in temperature, and GPS sensors to measure ground deformation. These data are used by scientists to monitor volcanic activity and assess the likelihood of an eruption.

Radon gas has been linked to potential earthquake predictions as elevated levels of radon gas emitted from the ground have been detected before some earthquakes. However, its effectiveness as a reliable predictor is still under research and not widely accepted.
Signs of an imminent volcanic eruption include increased earthquake activity, swelling of the volcanic cone, increased gas emissions, and changes in the composition of gas emissions. Monitoring these signs can help predict and warn of an eruption.
Chlorine, mustard gas and tear gas.
gas what do you think
Monitoring systems such as seismometers, GPS measurements, and gas sensors can help predict the occurrence of a volcano or earthquake by detecting patterns and changes in the Earth's activity. Scientists analyze these data along with historical trends to make informed predictions about potential volcanic eruptions or seismic events. However, predicting the exact timing and magnitude of such events remains challenging due to the complexity of Earth's processes.
Propane which is C3H8
It was called 'Mustard Gas'.
