Crescent City Harbormaster Mike Rademaker said a series of tsunami surges that swept into the inner boat basin may have caused “closer to $1 million” in damage on Wednesday.

H Dock bore the brunt of the energy, Rademaker said, but the concrete structure of the docks are “mostly still in good shape.”

“The metal connecting plates are sheared all over,” he said via text message just after noon on Wednesday, “and the 1.5 inch electric cabling will have to be completely replaced.”

The Crescent City Harbor District’s sacrificial dock did its job, taking the brunt of the energy spawned by a series of tsunami surges that arrived early Wednesday morning.

No injuries were reported from the tsunami, which occurred following a magnitude 8.8 earthquake off the east coast of Russia’s Kamchatka Peninsula, Harbormaster Mike Rademaker said during a community briefing at about 8 a.m. Wednesday. But H Dock sustained significant damage.

“At approximately 2:40 a.m. we noticed a surge of water several feet in height,” he said. “That caused the decking of H Dock to lift along its pilings. As the water level rose, the decking lodged on the pilings and was eventually submerged, [which] resulted in major structural failure and the complete separation of the dock.”
