A tsunami that never ends? Study highlights a looming West Coast risk.

“The pressure keeps building below the Earth’s surface off the coast of the Pacific Northwest, and a multi-layered disaster could strike at any time.

“A huge earthquake is brewing along the Cascadia Subduction Zone that could destroy bridges, reshape the landscape and trigger a massive #tsunami. Scientists have known about the looming danger for years, but ongoing #research keeps painting a clearer picture of what could happen.

“Among the dangers: A huge tsunami that will wash over coastal areas and permanently flood them... The quake is a certainty, but could be hundreds of years off...”

We were ruminating about whether it would ever be possible for good governance to mandate the pullback of wealthy coastal property owners.

Insurers rely too much on the billionaires' premiums (and share investments) ever to deny coverage to them, since those companies will always get the less privileged to subsidize landowners' liabilities, and underwriters are certain to get public bailouts after their inexorable losses.

So of course the answer is to defund all research.

Somewhere above the atmosphere is a satellite, and though I can’t see it, my face is always lifted at 45 degrees, pointing toward its geostationary position. My diaphragm rises and falls; my breath goes in and out like the #tides, and I stand and stare.

“Come away with us,” the dolphins and the sea otters say. “You’re no Andromeda, chained to the rock.”

It’s true there are no chains, but I’m locked on the satellite. Here I must stay until the release code comes.

Even though ‘glacial’ is commonly used to describe extremely slow, steady movement, a new study has found that #glaciers speed up and slow down on a daily – even hourly – basis in response to changes in air temperature, #rainfall and the #tides

There is a story attached. What you see is normally beach.

A combination of overnight sculpting of the sand, strong wind and high tide brought about an unexpected and rapid inundation.

I spent the afternoon on a sand dune, cut off by swirling flood waters.

High tide came and went at just the right time. Scary. Has given me a new respect for tide tables.

Via the #BBC @ 1:26am EDT on Sept 20, 2024

Coastal engineers are predicting very low #tides in the #UK later may be the lowest anyone will see again.
A low spring tide caused by the position of the #Moon and #Sun will create the "exceptionally" low tide, said #Exeter-based #MoffattAndNichol.
It said with sea levels rising, such a low tide may never be seen again.
It follows a 2022 report showing #SeaLevels are rising much faster than a century ago.

This is the biggest #tide on Earth, and it's in #Canada.

The #BayOfFundy is on Canada's East Coast and it sits between #NovaScotia and #NewBrunswick. And it's enormous.

Twice a day, these waters ebb and flow, and in some places, they rise up to 18 metres — that's nearly 60 feet.

At low tide, the waters recede up to five kilometres, leaving behind 1,000 square kilometres of mud.
