Watch: Time-lapse video shows tsunami impacting California coast
A time-lapse video recorded on Wednesday morning shows tsunami waves impacting Pillar Point Harbor in Half Moon Bay, California.
HALF MOON BAY, Calif. – The tsunami waves were caught on camera at the Pillar Point Harbor in Half Moon Bay, California, early Wednesday morning. The waves were a result of the historic magnitude 8.8 earthquake that originated off Russia's far eastern coast Tuesday.
The time-lapse video shows boats abruptly bobbing up and down several feet in the harbor over a five-and-a-half-hour span in the early-morning hours Wednesday.
The camera is part of the ALERTCalifornia system, a natural disaster public safety program between the University of California San Diego, Pacific Gas and Electric and other partners.
Half Moon Bay is about 30 miles south of San Francisco.
