What is a tsunami siren?
Quick Answer
A tsunami siren is an outdoor alarm used to warn people in coastal areas of an incoming tsunami. It is usually part of a broader emergency alert system that includes broadcasts, texts, and evacuation routes.
The Full Story
Tsunami sirens are designed to be heard over long distances, especially in low-lying coastal communities. They are often activated by emergency authorities after an earthquake or when a tsunami is detected by monitoring systems. Sirens are only one part of the warning chain; public education and fast evacuation are just as important. Many countries with tsunami risk, including Japan, the United States, Chile, and Indonesia, use layered alert systems. The goal is to move people inland or to higher ground before the first waves arrive.
