Geoelectric strike and its application in magnetotellurics

, 2014
Electrical resistivity methods in geophysical prospecting have been the most powerful tool in geothermal exploration. Determination of geoelectric strike angle in magnetotelluric (MT) measurements is a valuable contribution to an overall analysis of ...

The importance of non-uniform geoelectric fields in calculating GIC distributions

, 2013
During the ascending phase of solar cycle 24 concern in the power industry regarding space weather has increased significantly. This is driving the development of software tools to estimate GIC distributions in power networks for a given uniform ...

The geoelectric field: a link between the troposphere and solar variability

, 1998
The association of the European “Little Ice Age” (1550- 1850; Lamb, 1982) with a period of significantly reduced solar activity (Eddy, 1976) suggests a significant mechanism of climate variation remains to be ...

Regional-Scale High-Latitude Extreme Geoelectric Fields Pertaining to Geomagnetically Induced Currents

, 2015
Motivated by the needs of the high-voltage power transmission industry, we use data from the high-latitude IMAGE magnetometer array to study characteristics of extreme geoelectric fields at regional scales. We use 10-s resolution data for years 1993-2013,

A comparison of ground geoelectric activity between three regions of different level of seismicity

, 2007
In this work, we present a statistical study of geoelectric time series from three Mexican regions with recognized different levels of seismicity. This study is made by means of both the Higuchi's method and the detrended fluctuation analysis for ...

Localized Threats: How Ground Conductivity Shapes the Geoelectric Response

Space Weather
Geomagnetic storms can induce strong geoelectric fields in the ground. These fields drive geomagnetically induced currents in technological conductor systems, such as power grids.

Depth of Investigation and Vertical Resolution of Surface Geoelectric Arrays

, 2009
Depth of investigation and vertical resolution values are determined and tabulated for 30 surface geoelectric arrays that have non-zero response, i.e., a depth of investigation characteristic (DIC) function due to a buried thin horizontal sheet.
