The role of technology in the Chile aid effort: Children use a humanitarian calling station to contact their family
Children in the Chilean town of Duao contact relatives in the wake of the earthquake and tsunami. TSF has two strands of operations: one that helps set up communications for the aid agencies that go in to help in emergency situations, and the other to help the victims directly by setting up humanitarian calling stations like those in the photo, where people can call loved ones and family members to tell them they are safe.
When a natural disaster strikes, one of the essential services that fail is the communications network.
Telecoms Sans Frontieres (TSF) is a key part of the operation to re-establish links between people and help aid agencies co-ordinate their efforts. Currently, its work in Chile is providing crucial support to those affected by the 8.8-magnitude earthquake that struck the country on 27 February 2010.
