Blue zone

At the present time, Blue Zones appear to be the most friendly towards human life in the entire world and home to GDI. Blue zones are areas where Tiberium is kept strictly confined by resonator fields to particular areas, so that civilians can be kept away from these toxic zones, and do not risk Tiberium infection, as in the Red Zones. The Blue Zones cover approximately 20 percent of Earth. At the start of the Third Tiberium War, Nod launched an preemptive strike on nearly all of the Blue Zones.

Also, the Blue Zones fell under heavy attack from the invading Scrin forces, which amplified the destruction left in the wake of Nod's passing. The GDI drove all enemies back and afterward the attacks cause Tiberium to spread out of control.

Recent intel suggest some Blue Zones have been so contaminated by Tiberium that they have converted into Red Zones. Database operatives will continue to study this information.
