All of the Tsunami Detection Buoys in Indonesia are Damaged

Penelitian - Indonesia's National Disaster Management Agency (BNPB) said no longer had tsunami buoys to detect tsunamis since 2012. Sutopo Purwonugroho, BNPB Head of Information and Public Relations Center, complained about disaster mitigation which was constrained by budget problems.

"Since 2012 no one has been operating, even though it is needed for early warning. It can be asked to BMKG, why 2012 has not been held until now, maybe it's about funding," Purwonugroho told a press conference on handling of the earthquake in Dongala and tsunami in Palu, Central Sulawesi, Indonesia.

"The disaster funding continues to decline every year. The threat of disasters increases, the incidence of disasters increases, the BNPB's budget actually decreases. This affects the mitigation efforts. The installation of early warning tools is limited by a continuously reduced budget," said Sutopo.

In December 2017, Sutopo also stated the same thing that Indonesia had a total of 22 buoys scattered in the ocean which were totally damaged. Buoys are systems that place in the sea to detect tides and tsunamis. Buoys are one of the fastest early detection technology options for tsunamis in Indonesia.

"Yes, no more and no longer support data to BMKG," said Rahmat Triyono, BMKG Head of Earthquake and Tsunami Center.

Triyono said the buoy entered the Indonesian Tsunami Early Warning System designed since the 2004 Aceh tsunami. Buoys are installed at several points on the high seas, from the Indian Ocean to Sumatra, South Java and so on.

"In the open ocean, no one is watching. In fact, everything is lost. Lost by fishermen, some are taken, anchored, dragged using ships. Even those found in the ports taken by fishermen. Because there was a GPS, it was monitored and when it was grounded it was cannibalized, dismantled," said Triyono.

"As far as I know from 2007-2009 it has started to be installed on the high seas. But the system no longer supports the data to us at BMKG. What is clear is that 2011 has been installed and data should be entered into BMKG to support modeling," Triyono said.

Rahmat said the agency responsible for procuring buoys was the BPPT Technology Assessment and Application Agency, and not BMKG. He said BMKG could still carry out early warning functions without buoys, because their system was based on tsunami modeling.

"We have around 18 thousand tsunami modeling. But if there is data from the incoming buoy, the scenario will be more accurate," said Triyono.
