Local Atmosphere Heated Rapidly Before Japan Quake 202

eldavojohn writes "A new paper presented at NASA's Goddard Space Flight Center in Maryland shows the rapid heating of the atmosphere directly above the fault days before the devastating earthquake hit. This is theorized to be the Lithosphere-Atmosphere-Ionosphere Coupling mechanism that occurs when large amounts of radon are released due to massive stress in the fault right before the quake. This can be detected with satellites analyzing infrared waves: 'The radioactivity from this gas ionizes the air on a large scale and this has a number of knock on effects. Since water molecules are attracted to ions in the air, ionization triggers the large scale condensation of water. But the process of condensation also releases heat and it is this that causes infrared emissions.' This is a shift from the Haiti earthquake where DEMETER was used to monitor ultra low frequencies. The presence of radon could also possibly explain erratic wildlife behavior prior to an earthquake."
