Kulon Progo International Airport in Yogyakarta is designed to be resistant to earthquakes measuring up to 8.8 on the Richter magnitude scale as it was constructed in an earthquake-prone area, said Transportation Minister Budi Karya Sumadi in Jakarta on Friday.
The minister also said the airport was equipped with tsunami mitigation facilities.
“Don’t worry about [earthquakes] and tsunamis. Java does not experience earthquakes as strong as 8.8 on the Richter scale. We have also prepared the tsunami mitigation,” said Budi during a discussion at the Meteorology, Climatology and Geophysics Agency (BMKG) headquarters.
State-owned airport operator PT Angkasa Pura cooperated with the Bandung Institute of Technology (ITB) and the BMKG to design the airport in the earthquake- and tsunami-prone area, he said.
The minister added the Transportation Ministry had also involved engineers from the Indonesian Institute of Science (LIPI), the Agency for the Assessment and Application of Technology (BPPT) and the BMKG to draft the engineering design of Kolun Progo Airport, whose groundbreaking ceremony was held in January 2017.
For the tsunami mitigation, the BPPT had prepared six scenarios, with the chosen scenario consisting of three layers – sand mound, green belt (mangrove and pine trees) and a trench located 200 meters from the coastline, he added.
The tsunami mitigation facility needs 1.7 million cubic meters of sand and 50 hectares of green belt for the tsunami mitigation.
Under the scenario, only 1.1 percent of a tsunami's impact would affect the airport. (bbn)
