The scenario for EU MODEX Switzerland 2026 is a major earthquake causing very severe damage in the cantons of Geneva, Vaud and Fribourg. At the request of the cantonal authorities and the National Emergency Operations Centre, the Federal Council requests international assistance through the EU Civil Protection Mechanism (UCPM). The European Union mobilises response teams and resources from several countries. The aim of the exercise is to test the interoperability and cooperation of the various response modules in a host country.
