Do you know what a “sneaker wave” is?
If you don’t, you will after viewing this terrifying caught-on-camera moment at Moonstone Beach in Humboldt County on Jan. 11.
Marcella Ogata-Day posted a video of a sneaker wave knocking three unsuspecting people off their feet near the beach parking lot.
“Everyone was okay and a lot more alert,” Ogata-Day said on her Facebook page.
Sneaker waves most commonly occur in northern California, Oregon, and Washington.
