Three Americans were among those killed in the avalanche on Mt. Everest triggered by the massive earthquake that struck Nepal on Saturday, ABC News reported.

Seattle-based Madison Mountaineering said on its website that Marisa Eve Girawong was a camp medic who was killed when the avalanche hit the base camp where she was working.

Garret Madison of Madison Mountaineering confirmed Girawong's death in a recorded audio dispatch.

Google executive Dan Fredinburg was also killed in the avalanche.

The climbing group Jagged Globe wrote on its website, "It is with the greatest sorrow that we report the death of one of our Everest team members, Daniel Fredinburg."

Tom Taplin, a documentary filmmaker from Santa Monica, also died on Mt. Everest, his wife Cory Freyer confirmed to ABC News.

Taplin had been on the mountain for almost four weeks working on his documentary.

The State Department has confirmed three Americans died but has not released their identities.
