Tsunami advisory in effect for West Coast as volcano eruption creates waves

The National Weather Service issued a Saturday tsunami advisory for the West Coast of the United States.

An undersea volcano in Tonga that erupted Saturday local time has generated large waves that officials believe could affect parts of the U.S. The advisory extends to coastal areas in the Alaskan Peninsula, the Aleutian Islands, California, Oregon, southeast Alaska, south Alaska, Washington, and Hawaii.

“We don’t issue an advisory for this length of coastline as we’ve done — I’m not sure when the last time was — but it really isn’t an everyday experience,” said Dave Snider of the National Tsunami Warning Center, according to multiple outlets. "I hope that elevates the importance and severity for our citizens.”

Residents who live where the advisory was issued are encouraged to stay out of the water and away from the shore, including harbors and marinas, the NWS said.

Officials reported waves up to 2.7 feet in Hanalei, Hawaii, the Associated Press reported. So far, there have been no reports of injuries in the islands of Hawaii as a result of the conditions, the Pacific Tsunami Warning Center said in a tweet.

I laughed at that as well. Doesn't the ocean tide recede before a tsunami?

I have always been curious about an east coast tsunami alert. they have one with buoy markers or something. I imagine west coast is more advanced?
