The Korea Herald article:
"An interim tsunami warning system is operating in the Indian Ocean basin. The Inter-governmental Oceanographic Commission of the United Nations Educational, Scientific and Cultural Organization has overseen the installation or upgrading of tide gauges, deep ocean pressure sensors and seismic equipment across the region. This equipment is already transmitting information about climate, tide changes and other scientific data at hourly intervals.
"IOC teams have also been sent to several Indian Ocean countries to assess their needs with a view to helping them set up national plans for dealing with such disasters, including public education programs, communications and other vital infrastructure such as evacuation routes, emergency accommodation and medical facilities."
