Development and analysis of hybrid adaptive neuro-fuzzy inference systems for the recognition of weak signals preceding earthquakes
Prior to an earthquake, there is energy storage in the seismogenic area, the release of which results in a number of micro-cracks, which in effect produce a weak electric signal. Initially, there is a rapid rise in the number of propagating cracks, which creates a transient electric field. The …

Investigations of the b-value and its variations on possible earthquake prediction in the North-South China Seismic Belt
… studied extensively by researchers as a possible earthquake precursor. In this thesis, two different approaches to compute the b-value for the purpose of earthquake prediction are investigated and discussed. A new methodology, the b-value ratio method, inspired by a 1988 paper by Morgan et al., is …

Seismic precursor identification method integrating acoustic emission physical models and multi-source data
Earthquakes are among the most devastating natural hazards worldwide. Accurate earthquake prediction can significantly reduce disaster losses, yet seismic precursor identification remains one of the most challenging scientific problems of our time. Earthquakes result from macroscopic rock fracture …
