Iranian Volunteers Build Their Own Missile Alert System as War Continues

Crowdsourced Mahsa Alert App Provides Warning Map Amid Internet Blackout\n\nIranian volunteers have built their own missile alert system because the country lacks an official one, creating a crowdsourced warning map called Mahsa Alert.\n\n### The System\n\n- Crowdsourced website and app called Mahsa Alert\n- Provides citizens with missile and air raid warnings\n- Operating despite government internet blackout\n- Volunteers manually verify and report incoming threats\n- Named after Mahsa Amini, symbol of Iranian protest movement\n\n### How It Works\n\nVolunteers across Iran use the app to report sightings and sounds of incoming missiles, drones, and aircraft. The system aggregates reports in real-time to create a warning map that helps citizens seek shelter.\n\n### The Need\n\nIran doesn't have a national missile alert system like Israel's Iron Dome notifications or Western emergency broadcast systems. As the war with the US and Israel intensifies, civilians have been left without official warning infrastructure.\n\nSource: WIRED, Matt Burgess and Lily Hay Newman
