The Indian Ocean Tsunami warning system detects potential tsunamis through a network of seismographic and ocean monitoring stations across the Indian Ocean. When an earthquake occurs, data is transmitted to warning centers in Hawaii and Japan to analyze and issue watches or warnings. National warning agencies are meant to communicate these to other countries, though coordination could be improved. At the local level, organizations work to educate communities on tsunami safety and how to respond to warnings.
