Mild tidal surges of 3 to 4 inches from the magnitude-8.2 earthquake off Chile began hitting Crescent City at 10 a.m. Wednesday, but there was no damage along the North Coast.
HSU geology professor Lori Dengler said changes to Humboldt Bay's levels were basically nonexistent, while the beaches of Maui and Hilo, Hawaii, experienced surges of 1.5 feet.
”It was very, very small,” Dengler said. “You wouldn't see anything if you were there.”
In tsunami-prone Crescent City, the harbor received a surge of about 3 to 4 inches, she added.
The powerful quake forced residents along Chile's entire Pacific coast to evacuate, but the tsunami rose to only 8 feet. It resulted in sunken and damaged boats in Iquique that could cost millions of dollars to repair and replace.
Authorities on Wednesday discovered six reported deaths from the previous night's quake. It's possible that other people died in older structures made of adobe in remote communities that weren't immediately accessible, but it's still a very low toll for such a powerful shift in the undersea fault that runs along the length of South America's Pacific coast.
The U.S. Geological Survey said more than 60 significant aftershocks, including one of magnitude-7.6 on Wednesday, followed the Tuesday quake centered 61 miles northwest of Iquique.
