The department aims to fix all of the equipment in the six Andaman coastal provinces by the end of October, said deputy director-general Kobchai Boonyaorana.
“Out of the eight siren towers in Phang Nga, five are out of order. But all four broadcast towers are working,” he said, adding that out of 19 facilities in Phuket, 11 are out of order.
Mr Kobchai said part of the delay in the maintenance was due to the transfer period, as the National Disaster Warning Centre was moved from the former ICT Ministry to the DDPM, which is under the Interior Ministry. The transfer was completed in November 2016.
He said the budget has been allocated to the department, and it will work to repair the system and maintain the equipment on the basis of priorities.
Apart from the warning system in the six provinces, mainly focused on tsunamis, there are also disaster warning systems in other parts of the country, focusing on different kinds of disasters, said Mr Kobchai.
“We’ve got the budget already but repairs will take time, as some parts must be imported,” he said.
Suparaporn Jakmanon, acting director of the National Disaster Warning Centre, said B133 million has been allocated to take care of 3,067 disaster warning systems and related equipment.
Meanwhile, Mr Kobchai said the department will use other channels to alert the public, including television and radio, sending information to authorities at provincial, district and local levels. Line and SMS notifications will also be used, he said.
On the community level, local authorities would have to use every means to alert the public including radio, hand-held speakers, whistles and trucks equipped with loudspeakers, he said.
He said the first key to effective warning is the evaluation of the risks and the time available before the areas will be hit.
“Once an earthquake happens, we take around 10 minutes to analyse the information, and it can take up to 20-30 minutes to make sure if there is a high chance of a tsunami,” said Mr Kobchai.
Another factor is local people’s trust in the warning system. They also need regular drills, he said.
“We asked victims of recent flooding, whose damage was severe, whether they received warnings from authorities, and they said they didn’t, thinking the flooding wouldn’t come so fast,” said Mr Kobchai, adding that had contributed to doubts regarding the system.
Maitree Jongkraijug, a leader of a community-based disaster risk management team in tsunami-hit Baan Nam Khem in Phang Nga, said although the community are alert and ready to cooperate, effective collaboration is still needed between the department and local authorities.
The community recently opened a shelter tower that was built over a decade ago. Property rights issues prevented it being opened earlier.
