Indonesia tsunami: New warning system 'to be built next year'
Indonesia says it will build a new warning system capable of detecting tsunamis caused by undersea landslides, days after giant waves triggered by a volcano killed at least 429 people.
Installation of the new structure of buoys would start next year, a government agency told the BBC.
It is thought that activity by the Anak Krakatau volcano set off undersea landslides, causing Saturday's tsunami.
The new mechanism would work by detecting the size of waves, Iyan Turyana, a spokesman for the Agency for the Assessment and Application of Technology, told the BBC's Indonesian service.
The existing technology failed to predict the tsunami that devastated coastal towns around the Sunda Strait, between the islands of Sumatra and Java.
The system has been set up to monitor earthquakes, but not undersea landslides and volcanic eruptions, which can also generate deadly waves.
