The World Fire Alarm System monitors fires around the world using satellite data and provides notifications to subscribers. It offers three service levels - BASIC, PLUS, and PREMIUM - that vary in notification frequency and detail. BASIC subscribers receive SMS alerts every hour, while PLUS subscribers receive SMS and email alerts every 30 minutes with a map image. PREMIUM provides the most frequent and detailed notifications every 15 minutes by SMS and email with links to optimally-formatted map images. Subscribers choose their area of interest on the website and are then alerted if a fire is detected nearby.
