Bonn (dpa) - Since the beginning of the corona pandemic, the number of users of the "Nina" warning app has risen sharply.
The Federal Office for Civil Protection and Disaster Aid (BBK) announced on Monday that around 7.6 million people are using the app.
In March there were still around 6.1 million.
The office warns of dangers via the app.
These can be, for example, fires, the occurrence of radioactive radiation, but also power outages or natural hazards such as earthquakes or floods.
The latest developments on the corona pandemic are also announced via Nina.
The app will also be part of the warning day on September 10th.
For the first time since reunification, the warning technology will be tested nationwide on this day.
For this purpose, the sirens should howl at 11 a.m. and, in addition to the app, radio stations should also transmit the test warning.
"On the warning day we consciously go to the limits of the warning systems," said Christoph Unger, President of the Federal Office.
In this way, the office also wants to make the warning events better known.
In future, the warning day will take place every second Thursday in September.
