I did some research: It seems Hawaii boasts they hve the largest network of siren Alarms in the world. That cannot be true, even if you consider sirens per area. Hawaii has about one siren per 70(!!) square kilometer. Austria has about one siren per 10 square kilometer. European countries have extensive networks of warning sirens. Other examples are Switzerland with a siren per 9.8 sqkm (8200 total) and the Netherlands with one siren per 10.9 sqkm (3800 in total). I really don’t know which numbers would suggest that Hawaii has the largest system of Sirens in the world. If anything, the number of sirens seems excessively small. Also, for any Americans wondering: Air raid sirens in European countries trigger for natural disaster and other dangers to citizens too (like large fires)
