Earthquake precursors: A review of key factors influencing radon concentration.

Journal of Environmental Radioactivity, 2023
Many factors influence the accurate identification of radon anomalies triggered by earthquakes to varying degrees. Therefore, this paper primarily provides a comprehensive review of the various factors influencing radon concentrations over the past two ...

Identification of earthquake precursors in soil radon-222 data of Kutch, Gujarat, India using empirical mode decomposition based Hilbert Huang Transform.

Journal of Environmental Radioactivity, 2020
Soil radon (Rn-222) has been continuously monitored at Badargadh station (23.47°N, 70.62°E) in Kutch region of Gujarat to study the pre-seismic anomalies prior to occurrence of local earthquakes.

Episodic aseismic earthquake precursors

Nature, 1988
Shallow earthquakes are generally believed to be brittle fractures in a stressed medium with rupture velocity at a speed close to that for shear waves. We know, however, that the Earth allows failure over a wide range of timescales. Creep events occur on the San Andreas fault system, and for some earthquakes the high-speed rupture is accompanied by a ...

Earthquake Precursors Based on Rock Acoustic Emission and Deep Learning

The Scientist
China is one of the countries severely affected by earthquakes, making precise and timely identification of earthquake precursors essential for reducing casualties and property damage. A novel method is proposed that combines a rock acoustic emission (AE)

Meso- to nano-scale evidence of fluid-assisted co-seismic slip along the normal Mt. Morrone Fault, Italy: Implications for earthquake hydrogeochemical precursors

, 2021
Fluids play an important role in seismic faulting both at hypocentral depths during earthquake nucleation and at shallower crustal levels during rupture propagation.

Earthquake precursors

Bulletin of the Seismological Society of America, 1975
Abstract An analysis of existing earthquake precursor data leads to a conclusion that the precursors reported so far can be classified into three types, i.e., A1, A2 and B types. Most of type B precursors, observed in terms of anomalous tilts and strains or foreshocks, have no magnitude-dependent precursor time.
