The government is readying 100 buses to carry passengers from Bali to the nearest airports in case Denpasar's I Gusti Ngurah Rai International Airport is closed in the event of a Mount Agung eruption.

The Transportation Ministry estimates that at least 5,000 air passengers scheduled to depart from Bali could be affected in the event of an airport closure.

The ministry said officials have been prepared to take passengers overland to East Java's Blimbingsari Airport in Banyuwangi and Juanda International Airport in Surabaya, as well as to Lombok International Airport in West Nusa Tenggara (NTB).

The three airports are among the 10 airports being prepared to receive passengers and flights diverted from Bali.

"Of the 5,000 estimated air passengers that could be affected, 70 percent are believed to be [non-residents] while the remaining 30 percent are residents of Bali," Transportation Minister Budi Karya Sumadi said in a statement on Tuesday, suggesting that Balinese residents would not need to be transported to alternative airports.

The seven other airports being prepared are: Soekarno-Hatta International Airport in Greater Jakarta, which has only recently been added to the list; Adi Sumarmo International Airport in Surakarta, Central Java; Komodo Airport in Labuan Bajo, NTB; Hassanudin International Airport in Makassar, South Sulawesi; Sepinggan International Airport in Balikpapan, East Kalimantan; Sam Ratulangi Airport in Manado, North Sulawesi; and Pattimura Airport in Ambon, Maluku.

As of Tuesday, more than 80,000 people living near Mt. Agung have been evacuated as rising magma and increased tremors have fueled fears of an imminent eruption. (bbs)
