Nothing Escapes The Global Ear: Nuclear Tests, Volcanoes, Earthquakes or Meteors

The CTBTO has the only global network tracking radioactivity and sound waves

From earthquakes in Nepal to volcanic eruptions in Chile, from meteors crashing to Earth to the songs of migrating whales in the Indian Ocean, The Global Ear hears all.

This universal system of looking, listening and sniffing the Earth is the work of an international organization, the Comprehensive Nuclear-Test-Ban Treaty Organization or CTBTO.
