Earthquake-proofing Nepal's at-risk airport

Up to 20,000 passengers transit through Nepal's sole international airport daily

KATHMANDU, 2 April 2013 (IRIN) - If an earthquake the magnitude of Haiti’s 2010 quake were to strike Nepal’s capital area, the country’s only international airport would be crippled, with no backup plan for receiving essential relief. But now, in response to long-standing predictions of such a catastrophe, the government has endorsed an earthquake preparedness plan for Tribhuvan International Airport (TIA); the plan is set to become public in one month. 

Based on its most recent estimate, made in 2010, the National Society for Earthquake Technology-Nepal, said that if a 7.0-magnitude earthquake hit Kathmandu, it would kill an estimated 100,000 people, severely injure another 200,000, and displace 1.5 million. The disaster would damage 60 percent of homes beyond repair and wipe out almost all roads, leaving the airport as the last lifeline to transport relief supplies. 

The airport disaster response plan - prepared by the Civil Aviation Authority of Nepal (CAAN) and the TIA Civil Aviation Office, with support from the US Army Corps of Engineers (USACE), US Federal Aviation Administration and Canada’s University of British Columbia - was endorsed by the country’s National Aviation Security Committee in February. 

All governmental and nongovernmental groups will be legally bound to follow the plan’s directives following the high-level endorsement, TIA operations director Deo Chandra Lal Karn told IRIN. 

Emergency airport plan
The plan defines the responsibilities of the country’s civil aviation authority, airport officials and government agencies, including the Ministry of Home Affairs, Department of Immigration, Nepal Oil Corporation, police and army. It also covers communication, law enforcement, fire and rescue, medical care, and determining how relief will be delivered under severe duress. 

It indicates the UN’s World Food Program (WFP) will take the lead in coordinating logistics with the government, such as finding space at the airport to run two separate emergency operations - known as humanitarian staging grounds - for an estimated 1,000 aid workers. CAAN will take overall lead. 

The plan lays out the airport’s emergency response for the first 72 hours after a disaster, including recovery of critical facilities - including runways and air traffic control - as well as flight operations, land use, and short-term storage of relief deliveries. It covers the transit of domestic and foreign humanitarian assistance for 30 days. Assuming the state oil company will be hit, it also creates a backup oil depot to bunker fuel at the airport. 

Flashback to Haiti 
Nepal’s airport has been under close scrutiny since Haiti’s earthquake crippled its only international airport, preventing aid delivery for three days. The airport was only re-opened after the US military flew in communications and air-traffic management equipment and provided aluminium matting to boost the tarmac. 

Until then, planes loaded with food, water, medicine and rescue crews struggled to enter limited Haitian air space, with flights circling for hours before landing or being diverted. 

“All the aid airplanes that flew in Haiti were bottlenecked, and big airplanes were blocked or could not land easily,” said USACE project manager Patrick Fitzgerald.

Like Haiti, Nepal has only one international airport. 

A 2011 investigation found that TIA was at high risk of incurring damage, particularly its 3,000m runway. TIA’s Karn said a major earthquake would destroy three-quarters of the runway, leaving only some 1,800m to bring in humanitarian aid. The minimum runway length for the C-130, a military cargo plane used to transport emergency supplies, to land and manoeuvre at TIA’s altitude is 1,900m. 

TIA's taxiway - where planes are unloaded and serviced - is also inconveniently positioned, which could clog life-saving air traffic during an emergency. 

Still not enough 
“We're happy to see that the airport authorities are taking disaster preparedness very seriously, as their airport could be the key lifeline for millions of people in the Kathmandu Valley,” said Brett Jones, director of the US embassy’s Disaster Risk Reduction Office in Nepal. 

But a response plan is only a piece of paper without funding, say experts. 

Implementing the plan’s directives to stockpile emergency relief supplies at the airport, lodge humanitarian workers there and build a new oil depot all depends on funding, said Karn. 

“There is still lot of funding [needed] to back up the plan. We need a tremendous amount of resources, and we haven’t got any of those resources at the moment in the country,” said Andrew Martin, head of the UN’s humanitarian support unit in Nepal. 

WFP’s Emergency and Response Unit in Kathmandu told IRIN it will present its earthquake response plan (budget of US$1 million) - part of the overall airport emergency plan - to the government and UN humanitarian coordinator this month for endorsement.
