Prediction Capabilities of VLF/LF Emission as the Main Precursor of Earthquake [article]

Recent satellite and ground-based observations proved that in earthquake preparation period in the seismogenic area we have VLF/LF and ULF electromagnetic emissions.  ...  According to the opinion of the authors of the present paper this phenomenon is more universal and reliable than other earthquake indicators.  ...  Although, later, at the approach of critical value of tectonic stress, the balanced state in the system will be deranged and the earthquake will occur.  ...

We have discovered a new evidence of earthquake triggering due to the Sun-Earth interaction by simple comparison of a number of earthquakes before and after the strong solar flare.  ...  The main problem of this research is a lack of physical explanation of a mechanism of earthquake triggering by strong variations of space weather conditions.  ...  The work was supported by RFBR grant No. 18-05-00962.

Data from satellite observations serve as a powerful tool in monitoring earthquake preparation areas at a global scale and in a nearly real-time manner.  ...  The development of Earth observation satellites and anomaly detection algorithms can enrich available information sources, provide advanced tools for multilevel earthquake monitoring and improve short-  ...  A variety of machine learning methods have been used in thermal anomaly detection, which show great advantages in various fields in recent years and may have a considerable potential in this field.  ...

Revisiting the predictability of the Haicheng and Tangshan earthquakes [article]

Didier Sornette, Euan Mearns, Spencer Wheatley

We analyse the compiled set of precursory data that were reported to be available in real time before the Ms 7.5 Haicheng earthquake in Feb. 1975 and the Ms 7.6-7.8 Tangshan earthquake in July 1976.  ...  We demonstrate a strong evidence for the existence of an acceleration of the number of anomalies leading up to the major Haicheng and Tangshan earthquakes.  ...  Simulations indicate that, in ~93% of cases, alarm will be raised for an earthquake within the 10 days before the actual time.  ...

We aim at giving a short review of the seismo-associated phenomena detected on ground that in recent years have been investigated as possible earthquake precursors.  ...  In the present work, we give an overview of the observations carried out on ground in order to identify earthquake precursors by distinguishing them from the large background constituted by both natural  ...  conditions in the Earth-ionosphere.  ...
