Due to their potential application in earthquake forecasting, seismo-electromagnetic
phenomena were intensively studied for several decades all over the world. At present …

Earthquake is one of the most hazardous natural calamity. Many algorithms have been
proposed for earthquake prediction using expert systems (ES). We aim to identify and …

Detection of subsurface hydrodynamic anomalies plays a significant role in groundwater
resource management and environmental monitoring. In this paper, based on data from the …

Gutenberg-Richter 定理给出了地震频度随震级的分布特征. 大量研究表明频度-

Abstract Xu et al.(2013) and Han et al.(2015) have reported unusual behaviors of
geomagnetic diurnal variation (GDV) in the vertical component prior to the 2011 off the …

Despite the challenges in identifying earthquake precursors in intraplate (inland)
earthquakes, various hydrological and geochemical measurements have been conducted to …

The analysis of earthquake time series in a new time domain termed natural time enables
the uncovering of hidden properties in time series of complex systems and has been …

Pre-seismic anomalies have the potential to indicate imminent strong earthquakes in the
short to medium terms. However, an improved understanding of the statistical significance …

Prediction of earthquakes and volcanic eruptions has concerned researchers for many
decades. Several precursors (eg seismic, geodetic, geochemical, geological, atmospheric …

Insights into seismic precursors have been obtained in the last decades. However, a
detailed understanding of hydrogeochemical anomalies prior to earthquakes still remains …
