This article examines retrospective public-supplied precursor reports statistically, and confirms published hypotheses that some alleged precursors within 100km and within a day prior to the large 199...
A neuro-fuzzy approach to the reliable recognition of electric earthquake precursors
A neuro-fuzzy approach the reliable recognition electric earthquake precursors
2009/12/14
Electric Earthquake Precursor (EEP) recognition is essentially a problem of weak signal detection. An EEP signal, according to the theory of propagating cracks, is usually a very weak electric potenti...
Experience of short term earthquake precursors with VLF–VHF electromagnetic emissions
short term earthquake precursors VLF–VHF electromagnetic emissions

Electromagnetic anomalies (EMA) covering a wide range of frequencies from ULF, VLF up to VHF have been observed before recent destructive earthquakes in continental Greece. We show that the features o...

Short-term variations in sets of geophysical and biological parameters that were monitored at the Garm research site for a long time are considered in relation to an earthquake of magnitude M = 5.3. D...

In this case, it is possible that the pre-seismic processes could have produced irregularities in the troposphere, such as ducts, reflecting layers and scattering zones, so that some local troposphere...
