Geomagnetically Induced Currents in the Irish Power Network during Geomagnetic Storms
, 2016 Geomagnetically induced currents (GICs) are a well-known terrestrial space weather hazard. They occur in power transmission networks and are known to have adverse effects in both high and mid-latitude countries.

Strong geomagnetic disturbances and induced currents on Earth surface [PDF]
, 2008 Long-term variations in strong geomagnetic storms are analyzed and linked to electric fields induced on Earth. In fact, geomagnetic disturbances generate electric fields that drive currents in the Earth which may have significant effects on electrical ...

Combined three-dimensional electric and seismic tomography study on the Aknes rockslide in western Norway [PDF]
, 2010 We present a combined 3-D geoelectric and seismic tomography study conducted on the large Aknes rockslide in western Norway. Movements on the slope are strongly influenced by water infiltration, such that the hydrogeological regime is considered as a ...

Space Weather, Volume 23, Issue 11, November 2025.Abstract Geomagnetically induced currents (GICs) are naturally occurring electrical currents that flow through the Earth and long conductive infrastructure, such as power lines, during geomagnetic storms. GICs in the electric power grid can cause damage to electric power transformers, system failures, and wide‐scale blackouts.

Relationship between Interplanetary Conditions and Changes in the Geomagnetic Field to Understand the Causes of Geomagnetically Induced Currents [PDF]
, 2018 Geomagnetically Induced Currents (GICs) are electrical currents induced in ground-level conductive networks, like power lines and pipelines, which can cause costly damage to infrastructure.

Space Weather, Volume 23, Issue 11, November 2025.Abstract Geomagnetic storms can induce geomagnetically induced currents (GIC) in power systems, posing threats to grid security. In this study, a GIC calculation model for the 500 kV power grid in Guangxi, China, is developed based on one‐dimensional (1D) and various three‐dimensional (3D) magnetotelluric (MT) impedance data.

Geophysical assessment of subsurface conditions at proposed building sites: implications for foundation failure and building collapse [PDF]
, 2018 Building collapse has been a recurrent environmental hazard in Nigeria in the last two decades. This is a corollary of inadequate foundation investigation prior to construction, poor government policies, and general lack of awareness on the importance of
