The exercise is testing the use of social networks in a simulated earthquake and various aftershocks and is part of the European "Soteria" project that was held in Barreiro.

In the exercise, the officers on the ground were called to intervene in various emergency situations including helping victims buried under the rubble of a collapsed factory, spilt inflammable products and the search and rescue of three victims and a road accident where the car had fallen into the Tagus.
