Trading with the island nation of Indonesia
Every month, technology developed by Scottish firm HSL triggers a siren which sounds across the tropical island of Sumbawa in Indonesia.
The monthly alarm is a test of a system in place to provide vital early warning to workers and residents of extreme weather events including tsunamis and cyclones. Gold miner Newmont Mining Corporation monitors weather information for signs of problems looming. If necessary a command is activated through HSL's mobile communications technology to sound sirens in 10 locations around the mine.
