Tsunami Warning/Advisory From Asia to South America, July 29, 2025

[MacMadame]

Actually, that's what a tsunami is. It isn't just one major wave but a series of waves sloshing up against the shore - the water recedes & then returns with a larger wave against the wall of the bathtub/shore until the energy dissipates and the water calms again.

Oh, okay. I read something that said it wasn't.

Either way, the advisory has been canceled!! (At least where I am.)

Woke up to news that we are still under an advisory. Also, admonished not to go down to the beach to check things out. We are seeing what I think of as sloshing. Which is a big wave that goes back and forth. Except it's in the ocean and not a bathtub.

Woke up this morning, and beach access was gone.
Woke up this morning, and beach access was gone.
Big wave goin' in and out
Parks all been shut down

At least we're not in Kamchatka
With all the lava comin' atcha

Oh, I got the tsunami blues
Oh, I got the tsunami blues

Not just lava to worry about....

Encapsulated nuclear waste materials that were dumped by Russia are present at two deepwater seafloor locations in the offshore north-west Pacific Ocean, south-east of the Kamchatka Peninsula. This was the area in the news recently, due to yesterday's high magnitude earthquake that caused Pacific tsunami waves, and the subsequent stratovolcano eruption on land.
Thanks to page follower Mark D.Morehead, who wrote us to let us know this! In 1997, he led a team that authored a scientific paper assessing potential pathways by which those nuclear wastes might, if released from their containers, disperse away from the dumpsites and through the surrounding ocean.
They reviewed large-scale ocean circulation theory and of field and model results, and suggested that mean abyssal currents are moving north-eastward to eastward from the dumpsite locations and would advect leaking materials toward the north-eastern Pacific. Results of advective and diffusive horizontal plume transport models are consistent with this sense of flow. Trajectory speeds are, however, subject to considerable uncertainty. The results conveyed in their research paper suggest that as little as 5 years or as long as 100 years might be required for material to be transported from the dump sites to the north-east Pacific. Dilution by 4 or 5 orders of magnitude eas what they predicted during this transit. Vertical mixing or upwelling would be necessary in order to transport contaminants upward from north-east Pacific abyssal waters to the near-surface layers before they can potentially impact productive coastal regions, such as those off Alaska. Information concerning such upwelling mechanisms was inadequate for estimation of rates or to identify geographical areas that might be at risk." -- Content from the paper abstract; see below for the citation!

Well, we had some damage here in the harbor - one of the docks will cost an estimated $100,000 to repair. This particular dock was designed and built after the last tsunami to protect the harbor and it did its job, but sacrificed itself in the process. Unfortunately, the harbor is pretty broke due to some incredibly bad business decisions in the past and I'm not sure where they are going to get the $100,000 from. They are so broke they canceled some of their insurance policy provisions - bet they are sorry now.

There are reports that Oprah Winfrey has refused to open her private road on Maui

Those reports turned out to be false.

"Posts on social media contended Oprah Winfrey refused to open her private road, or was slow to do so during an evacuation. But the roadway does not belong to Winfrey, and efforts to open the road to the public started soon after the tsunami warning was issued."

FACT FOCUS: No, Oprah Winfrey didn't block access to a private road amid tsunami warning evacuations

Oprah Winfrey's representative and the president of Haleakala Ranch confirmed that a private road on Maui is owned by the ranch and not Winfrey.

"This is false. Despite being commonly known as “Oprah’s road,” the portion of Kealakapu Road is privately owned — but not by Winfrey. It belongs to Haleakala Ranch, which also owns the land surrounding the road, its president Scott Meidell told The Associated Press. Winfrey has an easement agreement with the ranch, which allows her to use and make certain improvements to the road, her representative told the AP in a statement. Winfrey has paved the road as part of the agreement, Meidell said."

The damage to our harbor has now increased to be about one million dollars after further assessment. FEMA won't pay for it due to damage being so localized so the harbor will ask the state to help, as the city did when part of a major road fell into the ocean.
