Observing Seasonal Variabilities of a Permafrost Landscape With PolSAR, InSAR and Pol-InSAR

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Synthetic aperture radar (SAR) remote sensing is an established approach for observing Earth processes. The combination of different types of SAR acquisitions in polarimetric, interferometric, and polarimetric-interferometric frameworks is well studied ...

Relation between seismicity and pre-earthquake electromagnetic emissions in terms of energy, information and entropy content [PDF]

Natural Hazards and Earth System Sciences, 2012
In this paper we show, in terms of Fisher information and approximate entropy, that the two strong impulsive kHz electromagnetic (EM) bursts recorded prior to the Athens earthquake (EQ) (7 September 1999, magnitude 5.9) present compatibility with the ...
