Germany will test a nationwide alarm system to warn of an impending emergency on September 14, authorities announced on Friday.
The German Interior Ministry and the Federal Office of Civil Protection and Disaster Assistance (BBK) said that German citizens will be warned at 11 am (0900 GMT) via various channels.
"We are relying on using a mix of warning methods," said ministry official Juliane Seifert.
The warning messages will be disseminated to radio and television channels as well as to mobile phones via warning apps like Nina.
Sirens and information boards in cities will broadcast the messages on public transit platforms and in trains.
BBK President Ralph Tiesler said, "It's going to be loud."
During the most recent test last December, nine out of 10 people in Germany received a warning by one means or another.
Efforts to improve communication with citizens in case of an emergency were stepped up in Germany after the deady flash floods that hit the west of the country in summer 2021.
