I don't know much about chemistry -Would the cause of the deaths be the increase of the radon amount or its ionization? And maybe the radon effects the temperature more than it does with human body.

The graphs were brilliant. Heat reaching the surface in reasonable time -mission impossible! I have to thank you for that! However there are other non related to heat conduction phenomena that may lead to an increase of the land surface temperature before earthquakes such as: - rising fluids that would lead to the emanation of warm gases - rising well water levels and CO2 spreading laterally and causing a ‘‘local greenhouse’’ effect - activation of positive-hole pairs during rock deformation - radon ionization of the near surface air and latent heat exchange due to variations of humidity I would be happy if you again disprove any of them

Those studies have used satellite data which are daily observations of the land surface temperature, so we are talking about above surface observations. Basically they have looked at the mean temperature based on other years and then compare the temperature of the earthquake year with the mean to seek for possible anomalies. Yes, I agree that the weather might mask a possible temperature anomaly. But I wouldn't agree that it would take months for the heat to reach the surface. If we take for instance an earthquake with a focal depth of 10 km, based on your assumption, the heat would travel up with a speed of only a couple of hundred meters per 24 hours. But if you agree with a release of heat, do you think that would be the case before or after the fault happens?

Several studies claim an increase of temperature 2-4 Celsius (3-7 Fahrenheit) few days prior to big earthquakes. The heat is supposed to come upward from gases released underground from pressure built. Also, increase of well waters and radon ionization above surface would contribute to the LST increase. In my view, if a relation between LST and earthquakes exist, that would apply just after an earthquake strikes. Isn't there a release of energy when an earthquake occurs and wouldn't this heat up the land above? Please state your opinion?

In Wikipedia page of Diurnal Temperature variation, there is a statement as following: "As solar energy strikes the earth’s surface each morning, a shallow (1–3 cm) layer of air directly above the ground is heated by conduction. Heat exchange between this shallow layer of warm air and the cooler air above is very inefficient. On a warm summer’s day, for example, air temperatures may vary by 30°F from just above the ground to waist height." First of all, do you believe it? And if you do, how comes that there is such a discrete temperature separation (a difference of up to 30°F) of these two layers (the 3 cm one and the one above it)?
