Radon as Earthquake Precursor [PDF]
Earthquake predictions are based mainly on the observation of precursory phenomena. However, the physical mechanism of earthquakes and precursors is at present poorly understood, because the factors and conditions governing them are so complicated. Methods of prediction based merely on precursory phenomena are therefore purely empirical and involve ...

Earthquake precursors: Banished forever? [PDF]
“When a rupture starts, how can it know where will it stop?” [Gregory Podyapolsky, 1973]Podyapolsky, a brilliant theorist, made this comment many years ago, upon perceiving that the earthquake prediction bandwagon in the Soviet Union was gaining speed. Twenty years later, we can observe just how far the bandwagon has gone.

Radon concentration anomaly characteristics in the North–South seismic belt before strong earthquake [PDF]
Seismic underground fluids play an important role in earthquake prediction studies and tracking. Nearly 30 years of radon concentration monitoring data at 42 observation sites in the North–South seismic belt (22°-35° N, 100°-110° E) were collected from ...

FUSION OF MULTI PRECURSORS EARTHQUAKE PARAMETERS TO ESTIMATE THE DATE, MAGNITUDE AND AFFECTED AREA OF THE FORTHCOMING POWERFUL EARTHQUAKES [PDF]
Since not any individual precursor can be used as an accurate stand alone means for the earthquake prediction, it is necessary to integrate different kinds of precursors. The precursors selected for analysis in this study include electron and ion density,

Discussion on common problems in data tracking and analysis of geomagnetics
The tracking and analysis of precursor network observation data is comprehensively carried out at precursor stations and regional centers. The event records generated by the tracking and analysis of earthquake precursor data demonstrate the dynamic ...
