The forecasting of local GIC effects has largely relied on the dB/dt as a proxy and, to date, little attention been paid directly geoelectric field or GICs themselves. We approach this problem with machine learning tools, specifically recurrent neural networks LSTMs by taking solar wind observations input and training models predict two different kinds output: first, components Ex Ey; second, i...

Geoelectric is the most popular geophysical method for groundwater exploration. This based on measuring electric current injected into earth and potential generated at surface. research was carried out Mount Tunak, island of Lombok, using Wenner electrode configuration. The data then processed Res2div software. survey conducted two lines obtained parameters, namely injection measured surface th...

Microtremor measurements and the horizontal-to-vertical spectral ratio (HVSR) technique, generally used for site effect studies as well as to determine the thickness of soft sedimentary layers, can effectively be applied to map the thickness of glaciers. In this work the radio-echo sounding, geoelectric and active seismic methods, widely employed to image the earth interior, are applied to veri...

The method of spherical elementary current systems provides an accurate modelling of the horizontal component of the geomagnetic variation field. The interpolated magnetic field is used as input to calculate the horizontal geoelectric field. We use planar layered (1-D) models of the Earth’s conductivity, and assume that the electric field is related to the local magnetic field by the plane wave...
