<P> In the Langtang valley located in Langtang National Park, 329 people were reported missing after an avalanche hit the village of Ghodatabela and the village of Langtang . The avalanche was estimated to have been two to three kilometres wide . Ghodatabela was an area popular on the Langtang trekking route . The village of Langtang was destroyed by the avalanche . Smaller settlements on the outskirts of Langtang were buried during the earthquake, such as Chyamki, Thangsyap, and Mundu . Twelve locals and two foreigners were believed to have survived . Smaller landslides occurred in the Trishuli River Valley with reports of significant damage at Mailung, Simle, and Archale . On 4 May it was announced that 52 bodies had been found in the Langtang area, of which seven were of foreigners . </P> <P> According to geological models, the frequency and intensity of future landslides in the Langtang Valley is due to increase in the coming decades . This is attributable directly to the effect of the earthquake, which caused widespread fracturing in the grounds of the Langtang area . </P> <P> Thousands of houses were destroyed across many districts of the country, with entire villages flattened, especially those near the epicenter . </P> <P> The Tribhuvan International Airport serving Kathmandu was closed immediately after the quake, but was re-opened later in the day for relief operations and, later, for some commercial flights . It subsequently shut down operations sporadically due to aftershocks, and on 3 May was closed temporarily to the largest planes for fear of runway damage . During strong aftershocks, the airport opened all boarding - lounge exit doors onto the tarmac, allowing travelers who were waiting post security and immigration to flee to the open spaces of the runway tarmac . Many travelers remained outside as planes were delayed and the airport swelled to capacity . The airport facilities suffered damage and there was no running water or operating toilets for travelers waiting in the airport lounges . Few airport workers were at their posts; most were killed in the earthquake or had to deal with its aftereffects . </P>
