If climbers want to summit Mount Everest, they have to brave the "death zone" - the area above 8,000 meters (26,247 feet) in altitude, where there is so little oxygen that the body starts to die, minute by minute and cell by cell.

Last week, at least 11 people died on Everest, which is the tallest peak in the world at 29,029 feet (8,848 meters or 5.5 miles) above sea level. Some reportedly collapsed from exhaustion after waiting in line for hours to ascend to the summit on narrow parts of the route.

But Everest isn't the only Himalayan peak on which climbers face the death zone. In fact, nine other mountains are deadlier than Everest.

According to NASA's Earth Observatory, Annapurna I - the 10th highest mountain in the world - is the most dangerous to climb, with a fatality rate of 32% as of 2012. K2, second-highest peak in the world, is almost as dangerous, with a fatality rate of 29%. Everest, by contrast, has a 4% fatality rate.

Granted, Mount Everest has seen many tragedies since 2012. In 2015, a magnitude 7.8 earthquake struck Nepal, sending an avalanche careening into Everest's Base Camp. More than 20 people were killed.

Here are the 10 deadliest mountains in the Himalayas - in order from most to least deadly - according to NASA.

According to NASA's Earth Observatory, only 191 people had successfully climbed Annapurna as of 2012, far less than any other 8,000-meter mountains.

The first people to climb Annapurna I were French climbers Maurice Herzog and Louis Lachenal in 1950. Though they reached the summit on their first try, extreme frostbite and gangrene set in on their way down the mountain. A doctor had to amputate all of Herzog and Lachenal's toes, as well as all of Herzog's fingers.

K2, or Mount Goodwin-Austin, is just 778 feet shorter than Everest. Mountaineer George Bell once said "K2 is a savage mountain that tries to kill you."

Only 264 people reached the top of K2 between 1906 and 2008, and 24 of them died before they got back down, according to 8000ers.com, an online database that tracks climbing statistics for all Himalayan peaks higher than 8,000 meters.

According to NASA, K2 has a fatality rate of 29%.

According to NASA, as of March 2012, Nanga Parbat had a fatality rate of about 20%.

In July 1953, Austrian climber Hermann Buhl became the first to reach the summit. He did so alone, without oxygen, food, a tent or sleeping bag. Before him, 31 people had died attempting that feat.

But the mountain is better known for how fast it's growing.

"There is no other mountain in the world that is rising as fast as Nanga Parbat," Mike Searle, a University of Oxford geologist, told NASA.

As of March 2012, Dhualagiri had a fatality rate of about 16%.

The route to Manaslu's summit presents similar challenges to Mount Everest's. The top of the mountain is a steep tower of rock that only has room for a few climbers at a time.
