An executive at Google was killed when a 7.8-magnitude earthquake rocked Nepal on Saturday morning and started an avalanche on Mount Everest, where he was part of a climbing team, his family said.

Dan Fredinburg was climbing Everest with a Jagged Globe expedition team when he suffered a fatal head injury, according to Jagged Globe and his family. He was one of at least 10 people killed on Everest and more than 1,300 people killed across Nepal in the quake.

Fredinburg’s sister shared the news of his death on social media:

At Google, Fredinburg was an engineer who focused on privacy, including for the Google X innovation lab, Re/code reports.

Two other members of his Jagged Globe group were also hurt in the avalanche on Saturday, Jagged Globe said, but they had non-life-threatening injuries.

Shortly before his death, Fredinburg posted this picture:
