Extremely Severe Space Weather and Geomagnetically Induced Currents in Regions with Locally Heterogeneous Ground Resistivity

Edited by: S. Fujita, R. Kataoka, I. Fujii, and A. Pulkkinen and S. Watari

The geomagnetically induced current (GIC) in the middle and low-latitude countries has been assumed to cause no serious damages on infrastructures on the ground. However, nobody has estimated how large the GIC would be in these countries during extremely severe geomagnetic storms like the Carrington storm in September 1859. Furthermore, the locally heterogeneous ground resistivity, which may unexpectedly boost local GIC intensity, has not been treated in the previous GIC studies.

Therefore, it is an important problem for scientists studying magnetic field variations in space and on the surface of the Earth to evaluate the extreme GIC in these countries.
