KATHMANDU, Nepal -- The death toll from an avalanche on Mount Everest triggered by last weekend's massive earthquake in Nepal has risen to 19, including two climbers from the United States and one each from China, Australia and Japan, mountaineering officials said Wednesday.

The other 14 victims were Nepalese Sherpa guides, the Nepal Mountaineering Association said.

The avalanche swept across Everest's basecamp area, injuring dozens of people, after Saturday's magnitude-7.8 earthquake. More than 5,000 people were killed elsewhere by the quake.

The association identified the American victims as Daniel Fredinburg, a Google executive, and Marisa Eve Girawong, a medic from New Jersey. It said Ge Zhenfang was from China, Renu Fotedar from Australia and Hiroshi Yamagata from Japan.

It said only 10 of the 14 Sherpa guides have been identified so far.

Mountaineering companies say all climbers have left the Nepal side of Everest and the climbing season is over following the disaster.

Saturday's earthquake struck just over a year after another deadly avalanche hit Everest, killing 16 Sherpa guides on April 18, 2014.
