Complementary Nature of Surface and Atmospheric Parameters Associated with Haiti Earthquake of 12 January 2010
TL;DR: In this paper, the authors describe surface (surface air temperature) and atmospheric parameters (relative humidity, surface latent heat flux) over the epicenter (18°27´25´´ N 72°31´59´´ W) of Haiti earthquake.
A statistical study on the correlation between lower ionospheric perturbations as seen by subionospheric VLF/LF propagation and earthquakes
Masashi Hayakawa,Y. Kasahara,T. Nakamura,Yasuhide Hobara,Alexander Rozhnoi,Maria Solovieva,O. A. Molchanov +6 more
TL;DR: In this article, an extensive period of data over seven years from January 2001 to December 2007 and a combination of different propagation paths in and around Japan are used to examine the statistical correlation between the VLF/LF propagation anomaly (average nighttime amplitude, dispersion and nighttime fluctuation) and earthquakes with magnitude greater than 6.0.

Radon-222: A Potential Short-Term Earthquake Precursor
Ermioni Petraki,Dimitrios Nikolopoulos,Dionisios Panagiotaras,Demetrios Cantzos,Panayiotis H. Yannakopoulos,Constantinos Nomicos,J. Stonham +6 more
TL;DR: In this paper, a series of papers were searched to collect relevant data, such as the epicentral distance, the extent, time and duration of the radon disturbance and to analyze the precursory value of each observable.

On the seismogenic increase of the ratio of the ULF geomagnetic field components
TL;DR: In this article, the authors investigated the reliability of the ULF magnetic polarization ratio changes as an earthquakes' precursor, and found that the suggested association between the geomagnetic field polarization ratio increases and the earthquake preparation process seems to be rather doubtful.

Estimation of the size of earthquake preparation zones
TL;DR: In this article, an approximate solution of the problem for a soft elastic inclusion in an elastic half-space is presented. But the authors assume that the moduli of the inclusion differ slightly from those of the surrounding medium (by no more than 30%).
