Equatorial regions are prone to disruptive space weather, new study finds
Washington DC (SPX) Aug 18, 2015
Extreme space weather has long been seen as a threat to electrical grids in high-latitude regions of the northern and southern hemispheres. A new study finds that smaller space weather effects are amplified near the Earth's equator, putting power grids at risk in regions long considered safe from bad space weather. Massive space weather events have crashed power grids across North America and Europe, but the new report warns that smaller events strike - often with little warning - in equatorial re ... read more
