Mount Everest unconquered for first time in four decades

London : 2015 was the first year since 1974 in which not one person managed to reach the top of Mount Everest.The year 2014 saw the highest death toll on Earth’s highest mountain with 24 people being killed in a single day in April following a 7.8 magnitude earthquake in Nepal causing a massive avalanche.It was the deadliest day in the history of Mount Everest.The Nepal earthquake killed more than 8,000 people across the country and injured more than 21,000 in 2014, The Telegraph reports.The failure of any climbers to reach the Himalayan summit in 2015 is partially due to the shutting of the mountain after the devastating earthquake.The Nepalese government was initially keen for mountaineers not to cancel their expeditions after the avalanche, but broken ladders on the mountain and a second quake in early May compelled the authorities to abandon the plans.
