We are studying the possibility of a connection between
atmospheric observation recorded by several ground and
satellites as earthquakes precursors. Our main goal is to
search for the existence and cause of physical phenomenon
related to prior earthquake activity and to gain a better
understanding of the physics of earthquake and earthquake
cycles. The recent catastrophic earthquake in Japan in
March 2011 has provided a renewed interest in the
important question of the existence of precursory signals
preceding strong earthquakes. We will demonstrate our
approach based on integration and analysis of several
atmospheric and environmental parameters that were found
associated with earthquakes. These observations include:
thermal infrared radiation, radon! ion activities; air
temperature and humidity and a concentration of electrons
in the ionosphere. We describe a possible physical link
between atmospheric observations with earthquake
precursors using the latest Lithosphere-Atmosphere-
Ionosphere Coupling model, one of several paradigms used
to explain our observations. Initial results for the
period of2003-2009 are presented from our systematic hind-
cast validation studies. We present our findings of multi-
sensor atmospheric precursory signals for two major
earthquakes in Japan, M6.7 Niigata-ken Chuetsu-oki of
July16, 2007 and the latest M9.0 great Tohoku earthquakes
of March 11,2011
