King Tides

[terracore]

Big Tides= more earthquakes? https://www.scientificamerican.com/artic...rthquakes/

They aren't new but they are breaking all recorded records now.

The April king tide surpassed Hawai‘i’s 112-year-old record—raising 9 inches above the predicted tide levels, according to the National Oceanic and Atmospheric Administration.

These anomalies are expected to continue through the summer and could affect the size of future king tides occurring June 23–24 and July 21–22. NOAA predicts that the June and July king tides will be higher than both the April and May tides.

112 years? That's a blip in time. plus, remember that the island is sinking under its own weight.

Because I'm sure scientists didn't take that into account...

Leilanidude always the contrarian. Nice guess, but it's not right. This is a well known aspect of tidal gauge data in the islands and the record was set on Oahu, which data shows is not sinking. The trend of rising tides can be correlated to a decade of differential GPS measurements at those tidal stations. Scientists, like at NOAA, are well aware of land effects and tide levels when analyzing the data for long term trends.

Since 1946, sea level at Hilo on the Big Island of
Hawaii has risen an average of 1.8 ± 0.4 mm/yr faster than
at Honolulu on the island of Oahu. This difference has been
attributed to subsidence of the Big Island. However, GPS
measurements indicate that Hilo is sinking relative to
Honolulu at a rate of 0.4 ± 0.5 mm/yr, which is too small
to account for the difference in sea level trends.

NOAA says the tides that day reached a record of 3.08 feet, the highest in the 112 years since tide data has been monitored. Also you can see expected vs. verified for that month:

leilanidude, the other day, on another thread when I brought up the time period in which Kings ruled you said:

Another deflection..
We aren't discussing 1800's policies.

On this topic, discussing the present day you injected into the discussion:

King Tides are nothing new. They have been around since.. well.. the kings... and before...


I'm sure there's an exception for one statement but not the other, so one comment can be proved with a partial truth, and the other dismissed with a brusque, confident yet unsubstantiated rejection. It no doubt demands a great deal of effort to keep track of the details required for such a juggling act, so facts can be transmuted into beliefs which justify short term tax cuts. While at the same time islands such as Kiribati, the Maldives, Seychelles, Tegua, Palau, Tuvalu, Niue are submerged, and their inhabitants must abandon homes due to the rise in sea level, as well as negotiate around King Tides which regularly erode and spirit away large stretches of their shoreline. They have little choice but to make due with less or move far away. But hey, too bad for them, I got mine. And more.

Here on the Big Island however, life goes on. This morning at low tide, I watched an opihi picker working slowly, carefully on the rocks at the waterline, as small waves washed over his legs. The King Tide won't affect him much today as it will others with homes and businesses in low lying areas across the island chain.

Hopte, again.. you tried to ignore the fact...
112 years in time does not make a record...
Why do you think they are called "King Tides"?

"It no doubt demands a great deal of effort to keep track of the details required for such a juggling act, so facts can be transmuted into beliefs which justify short term tax cuts."

Quite a mouthful of words, HOTPE. I had to read that several times.

At any rate, more reason here for new shoreline setback rules, which many of our affluent shoreline owners oppose. I particularly enjoy watching situations where people in power assert that they are going to continue doing things just as they desire--and that no one is going to tell them otherwise--and then nature starts intervening. Repeatedly. (factor: sea level rise)

The term King Tides was barely heard several years ago. Think this recent event was bad? This is just the beginning.
