A Warning Sign? Atmosphere Above Epicentre Of Deadly Japan Earthquake Heated Up 'Rapidly' In Days Before Disaster -- The Daily Mail
* Scientists hope they will one day be able to predict quakes uses air ionisation data.
The atmosphere directly above the fault zone which produced Japan's recent devastating earthquake heated up significantly in the days before the disaster, a study has shown.
Before the March 11 earthquake, the total electron content in a part of the upper atmosphere, called the ionosphere, increased dramatically over the earthquake's epicentre, reaching a maximum three days before the quake struck.
It is believed that in the days before an earthquake, the stresses on geological faults in the Earth's crust causes the release of large amounts of radon gas.

My Comment: This is a remarkable discovery that deserves further research.
