There has been enormous progress in the field of electromagnetic phenomena associated
with earthquakes (EQs) and EQ prediction during the last three decades, and it is recently …

The purpose of this paper is to discuss the lithosphere–atmosphere–ionosphere coupling
(LAIC) effects with the use of multiparameter precursor observations for two successive …

In order to explore the abnormal disturbance of the space electric field caused by
earthquakes using the electric field data of the ULF and VLF frequency bands of the electric …

To explore the correlation between earthquakes and spatial ultra-low frequency electric field
disturbances and to study the phenomenon of seismic ionospheric disturbances, this study …

The study presents seismogenic ULF (ultra-low-frequency) wave effects, as observed at our
own new magnetic observatory at Asahi (geographic coordinates: 35.770° N, 140.695° E) in …

Single-stationed geomagnetic vertical intensity polarization (GVIP) anomalies have
demonstrated good predictions of the occurrence of large earthquakes in Japan …

Recent studies reported that the diurnal variation of the geomagnetic field exhibited
anomalous characteristics several months before earthquakes (EQs). However, the …

Extracting weak seismic-magnetic signals from strong electromagnetic backgrounds has
always been an important part of seismic-electromagnetic research. Based on the data of …

The observation of geomagnetic anomalies appearing prior to earthquakes (EQs) is
theorized to be generated by underground seismic processes. However, these pre EQ …

Observations of earthquake precursors via geomagnetic anomalies from ultra-low frequency
(ULF) could provide an expectation for short-term earthquake prediction. However, there are …
