Visualizing Air Raid Sirens in Ukraine by @mourner

As Ukraine continues to heroically resist Russia’s invasion, Ukrainians have to face new realities of war. One of them, a constant presence in our daily lives, is Air Raid Sirens — a loud sound indicating the threat of imminent attack from the air and a call to take shelter immediately. In the digital age, instead of loudspeakers, most people rely on mobile apps like Air Alert, which allows you to choose a region and get emergency alerts for it. It also has a Telegram channel which doubles the alerts.
