Mechanism of the lithosphere earthquake precursor anomalous phenomena
|
Abstract:
It is still an unsolved question how the electromagnetic anomalies observed on the electromagnetic satellite move from the Lithosphere to the ionosphere or the aerosphere.In this paper I collect lots of anomalous mechanism about the lithosphere earthquake and want to acquire the corresponding understanding from the source of the electromagnetic anomalous phenomena-lithosphere earthquake.It includes: bulging of the Earth's surface,changing of the well water levels,ground-hugging fog,low frequency electromagnetic emission,earthquake lights from ridges and the tops,magnetic field anomalies up to 0.5% of the Earth's dipole field,temperature anomalies by several degrees as seen in the satellite images,changes in the plasma density of the ionosphere,and the strange animal behavior and so on.Now several hypotheses were introduced to try to interpret the diverse anomalies,including thermal anomalies on the Earth surface with the Atmosphere-lithosphere coupling,gas-fluid "bubble",upward migration,crack propagation and the motion of charged edge dislocation,Positive-hole-pairs(PHPs) motion and so on.Earthquake precursor anomalous phenomena's process and the mechanism studied and the explanation are discussed in the paper.Although there are some defects in these hypotheses,it would give us a powerful help to correctly realize the electromagnetic anomalous phenomena with the development of study on the mechanism of the Lithosphere Earthquake precursory anomalous phenomena step by step.
