He was a Google engineer and avid climber who sought to take the company’s Street View project to the world’s tallest mountains.

On Saturday, Dan Fredinburg was at a base camp on Mount Everest when a powerful earthquake in Nepal set off an avalanche. Mr. Fredinburg was killed, Google said in a statement posted on its website.

“Sadly, we lost one of our own in this tragedy,” the statement said. “Dan Fredinburg, a longtime member of the Privacy organization in Mountain View, was in Nepal with three other Googlers, hiking Mount Everest. He has passed away. The other three Googlers with him are safe, and we are working to get them home quickly.”

Shortly before, an Instagram post on Mr. Fredinburg’s account went up: “This is Dan’s little sister Megan,” the message began. “I regret to inform all who loved him that during the avalanche on Everest early this morning our Dan suffered from a major head injury and didn’t make it.”
