Geomagnetically Induction effects related to impulsive Space Weather events at low latitudes

Geomagnetically induced currents (GICs) regularly damage the technological infrastructures in high latitude regions. Its effects have also been observed in middle and low latitudes (South Africa, China.) (Gaunt and Coetzee, 2007). In view of these dangers, we study the GICs at low latitudes in order to determine the level of induction associated to the solar events which are the cause of these induced currents.

We estimate GIC intensity by two methods. Firstly, we use measured geoelectric data to infer GIC and secondly, we calculate geoelectric field data by geomagnetic field data and infer GIC.
