Tsunami early warning must start at community level

Multi-hazard approach

Communities must also design their own warning messages.

"We don't want to see panic, we don't want to see people taking the wrong action. So getting the words right, getting the message right and getting it delivered are key components," said Al Panico, head of the tsunami unit at the IFRC.

In order to maintain the tsunami early warning system, at the community, national and international level, it is vital to extend it to other hazards like cyclones and storm surges.

"Any warning system you don't notice is a dormant system, and treasuries don't like anything that they cannot justify," said Peter Koltermann, head of the Tsunami Coordination Unit for the United Nations' Intergovernmental Oceanographic Commission (IOC), which began coordinating the Indian Ocean system in 2005.

The best approach to saving lives, however, is better urban and coastal planning to move people away from high risk areas. But experts agree this is the hardest thing to accomplish when communities and livelihoods are established.

"That is by far the best approach," said Panico. But "it's the individual who decides where to live."
