One passenger was struck and killed by glass during an Antarctic Cruise this past week, media outlets report. The incident occurred when a rogue wave struck the Norwegian-flagged Viking Polaris during a storm as the ship sailed toward Ushuaia, Argentina.

The victim was a U.S. woman who “received blows from a glass surface that collapsed in the middle of the storm,” the Argentine news agency Telam reports.

Four other passengers sustained non-life-threatening injuries during the incident and were treated by the ship’s onboard doctor and medical staff.

“It is with great sadness that we confirm a guest passed away following the incident,” Viking said. “We have notified the guest’s family and shared our deepest sympathies. We will continue to offer our full support to the family in the hours and days ahead.”

The 662-foot ship sustained “limited damage” after being struck by the wave, Viking said.

Rogue waves can be double the size of surrounding waves, states the National Oceanic and Atmospheric Administration. The waves often come unexpectedly from directions other than the prevailing wind.
