Multi Sensor Approach of Validating Atmospheric Signals Associated with Major Earthquakes
International audience The recent catastrophic earthquake in Haiti (January 2010) has provided and renewed interest in the important question of the existence of precursory signals related to strong earthquakes. Latest studies (VESTO workshop in Japan 2009) have shown that there were precursory atmo...
