September 14th is another nationwide warning day. At 11 a.m., various warning devices from the MoWas modular warning system sound the alarm on a test basis. This includes mobile phones, sirens, loudspeaker trucks, digital information boards, Deutsche Bahn information systems, social media, radio and television.
This is used to test the technical processes for emergencies. The Federal Office for Civil Protection and Disaster Assistance (BBK) tests which warning devices work every year and optimizes them if necessary. The warning day is also intended to raise people’s awareness of the different warning devices. The all-clear was given at around 11:45 a.m.
A cell broadcast alert every 36 hours
The test alarm reaches smartphones and mobile phones not only via a warning app such as NINA, Biwapp, KatWarn or Warnwetter from the German weather service, but also via the cell broadcast service Cell Broadcast (SMS-CB) – the German authorities call it DE-Alert.
This warning method was first tested in September 2022 by the BBK and Telekom, since February 2023 Telefónica and Vodafone have also been involved. According to BBK, the last warning day reached more than 90 percent of 833,000 respondents via various channels. A warning is now sent via Cell Broadcast on average every 36 hours.
This year too, the BBK has created a survey in which all German citizens can take part. It will be activated after 11:45 a.m. on September 14th and will provide information about how the warning day went. In addition, the BBK provides a wide range of information material – including school material for children about Cell Broadcast.
