Triplicate staff report
The National Weather Service called off a tsunami advisory for the Pacific coast that includes Del Norte County.
The advisory, issued Friday night, indicated a tsunami was possible but not expected from San Diego north to Vancouver Island in British Columbia. Weather service officials called off the advisory early Saturday morning.
Though a tsunami was not expected in the Crescent City area, should one have been generated, weather service officials estimated it would have struck this area at 4:45 a.m. Saturday. It would have reached Seaport, Ore., at 4:46 a.m.
A 8.3-magnitude earthquake struck 310 miles east of the Kuril Islands and northeast of Japan in the Pacific Ocean at 8:24 p.m. Pacific time. The quake occurred at a depth of 19 miles below the seabed.
Tsunami advisories were canceled Saturday in Alaska and Hawaii after officials determined waves from a powerful earthquake in the northern Pacific were too small to pose a threat.
A tsunami of less than 4 inches was recorded Friday night at Shemya, Alaska, at the western end of the Aleutians, the National Weather Service said.
andquot;It's one of those situations where the indications are, when you look at Shemya and the other places in Japan, it really doesn't meet the criteria to be destructive,andquot; said National Weather Service spokesman Greg Romano.
A tsunami watch issued in Hawaii was also canceled.
The largest wave reported by Saturday morning was a 16-inch tidal surge along the shores of Chichi-jima, a Pacific island 620 miles south of Tokyo, more than three hours after the quake.
Earlier, a tidal swell of about 4 inches was recorded in Japan's northeastern coastal town of Nemuro, and a higher tide also was observed in other coastal towns, including Kushiro, Abashiri and Otaru, Japan's Meteorological Agency said.
A tsunami most recently struck the Crescent City Harbor on Nov. 15 following an earthquake near the Kuril Islands. Waves reached 5.9-feet in height and caused $1.2 million in damage.
