Atmosphere above Japan heated up before earthquake says NASA

The atmosphere above Japan was observed by NASA to heat up rapidly several days before the Great Earthquake, probably caused by stresses in the fault releasing massive amounts of radon.
"Briefly, the primary process is the ionization of the air produced by an increased emanation of radon (and other gases) from the Earth’s crust in the vicinity of active fault. The increased radon emanation launches the chain of physical processes, which leads to changes in the conductivity of the air and a latent heat release (increasing air temperature) due to water molecules attachment (condensation) to ions."
