If you want to climb the high altitude mountain then you should be careful. But rather than Mt Everest, the other nine mountains are deadlier and have a high death rate. According to NASA theres only a 4% death rate on Everest which makes it no.10 deadliest mountain in the world. But it doesn’t mean there’s no death in Mt Everest; less than 5 people die among 100 people after summit attempts. Likewise, Annapurna I which is 10th highest mountain has a 32% fatality rate and K2 or Mount Godwin-Austen has a 29% fatality rate, Nanga Parbat has a 20% fatality rate and many more. Thus, you can find more deadliest mountains than Mt Everest, even though it’s the highest mountain in the world.
