This initiative focuses on providing rapid, verified information during events such as floods, fires, blackouts, or radiation accidents. A central component of this effort is the testing of the Automatic Safety Alert (ASA) system. Utilizing DAB+ digital broadcasting, the technology can automatically wake compatible receivers from standby mode to broadcast updates on the Radiožurnál news channel. This radio-based approach is intended to remain functional even if mobile networks, the internet, or electricity fail. In addition to radio developments, authorities are preparing to implement Cell Broadcast technology. This method allows for the simultaneous transmission of warning messages to all mobile phones within specific high-risk areas, offering a faster alternative to traditional SMS. ## Timeline ### 2026-09-26: Czechia tests new emergency warning systems via radio and mobile Czechia is testing new emergency warning systems, including ASA technology for DAB+ radios and Cell Broadcast for mobile phones, to ensure reliable alerts during disasters. 4 sources. https://clstr.news/cluster/czechia-tests-new-emergency-warning-systems-via-radio-and-mobile ### 2026-09-14: Czech Radio partners with rescue services for new emergency alert system Czech Radio is partnering with the Integrated Rescue System to launch the Automatic Safety Alert (ASA) system, which uses radio broadcasting to provide rapid emergency warnings during crises. 2 sources. https://clstr.news/cluster/czech-radio-partners-with-rescue-services-for-new-emergency-alert-system --- Cite as: Czech Republic emergency alert system development.
