The government asked Mandalika circuit developers to conduct seismic surveys before construction
The Republic of Indonesia Meteorology and Geophysics Agency reminded about the vulnerability of the earthquake in the Lombok region, especially the central part. The 2021 MotoGP performance plan in the Mandalika Special Economic Zone must be able to anticipate disaster risk early on. Thus, it is important to conduct an Earthquake Vulnerability Microzonation survey to measure the extent of its vulnerability to earthquakes.
Microzonation is one technique to divide a large zone into small zones with the criteria of each zone. Included in seismic zoning. While surveys are needed to map out the real potential of earthquakes that have the potential to occur based on the history of events and the existence of active faults.
According to the Head of Mataram Geophysics Station, Agus Riyanto, this survey is very important as part of disaster mitigation in the Mandalika Special Economic Zone.
At coordination meeting on Mandalika disaster mitigation preparation attended by Meteorology and Geophysics Agency and West Nusa Tenggara regional government on 4th of April, Agus Riyanto expressed the need for a Microzonation survey to be conducted. There is even a commitment from the management of the Indonesia Tourism Development Corporation (ITDC), I Wayan Karioka, to finalize the support of broadband seismic shelter land in the region. Also present at the West Nusa Tenggara Regional Secretary meeting, Rosiady H. Sayuti.
’’In the meeting, we (the Meteorology and Geophysics Agency) submitted a proposal to conduct a microzonation survey at Mandalika,’ he said. But so far there has been no follow-up. He also sent hearing letter to the Governor of West Nusa Tenggara, but there was no response.
“We don’t want the involvement of the Meteorology, Climatology and Geophysics Agency to be carried out in the final stages of construction, because mitigation programs may be too late to do,” he said. Especially in the recent seismic record, active local faults under Mount Rinjani, could have triggered a 5.4 magnitude earthquake.
Agus hopes that the ITDC, West Nusa Tenggara Provincial Government and Central Lombok Regency Government will seriously examine these mitigation efforts. Natural disasters, according to him, cannot be eliminated, but the impact can be minimized through mitigation process. Moreover, the success of MotoGP will be an indicator of the economic progress of West Nusa Tenggara and Indonesia in general, which is capable of hosting world events.
