With hundreds of seismic, infrasound, hydroacoustic and radionuclide-detecting stations operating continuously around the world, CTBTO scientists - and, increasingly, researchers outside the organization - are realizing the potential of all the data collected. CTBTO data have been used to understand major natural events such as the 2013 Chelyabinsk meteor and the 2011 Japanese earthquake, tsunami and eventual nuclear disaster. And in the future, it may contribute to improved volcano monitoring and understanding of atmospheric processes.
