Concept and implementation of “Disaster-free network”

Every year around the world, we suffer from disasters. For some countries, earthquakes are the largest threat among natural disasters. It is difficult to forecast them, and their impacts are huge. An earthquake occurred in March, 2011 in Japan, and the massive tsunami triggered by that earthquake was a stark reminder of the severe damage that is possible with such a huge earthquake. Similar damage occurs every few years worldwide. In addition, global warming results in stronger and more devastating natural disasters. Consequently, disaster management has become even more crucial for many network operators.
