Preseismic Atmospheric Radon Anomaly Associated with 2018 Northern Osaka Earthquake

Caption

Image showing the exhalation of radon (222Rn) gas from underground. The concentration of radon in the atmosphere is measured at radioisotope (RI) facilities. Radon exhalates to the ground surface through microcracks (fissures) in the rock that occur before and after earthquakes.
