Quakefeed has been sending out dozens of alerts over the last few days.
Some quakes are quite large 6+ and all are clustered in a small patch of very deep water just south of kodiak.
An undersea volcano maybe?
Im curious to see what the effects of a deep undersea quake would be on a fishing vessel or container ship travelling across the top.

Coming up to a full moon, time for the US to sell Alaska to the Canadians. :ok:

They are aftershocks after a large (7.9) earthquake triggered Pacific tsunami watches a few days ago. Nothing unusual.

Undersea earthquakes and volcanoes have little effect on the sea above them until or when they break surface. Tsunami only become dangerous when they reach shallow water.

The sea surface only rose 32 feet during the large quake this week.

Undersea earthquakes tend not to break the surface. The situation is far more complicated than just having something reach the ocean surface. In the recent Alaska EQ, it was fortunate it was a slip fault where the plates slid sideways and not vertically otherwise there may well have been a Pacific-wide tsunami - it was a strong enough EQ to do that.

jolihokistix - I've seen this claim, but haven't seen any evidence to support it.

Second time I have had to run a search for this!

And as we now know, there was no 32-foot wave. It was because the buoy provided incorrect data as it was so close to the EQ.

E.g., https://www.adn.com/alaska-news/2018/01/25/the-case-of-the-phantom-tsunami-why-an-alaska-buoy-showed-a-big-wave-that-wasnt-there/

There are times when you have to use common sense to differentiate between fact and fiction and this was one of them.

Agreed.


It took the authorities several hours to work this one out though; always better to err on the safe side!

Agree with being on the safe side. However, the tsunami watch in Hawaii and for the Pacific region was canceled about two hours after the EQ. I don't call that several hours.

It was a frightening time for people on the west coast of Alaska and nearby coastal regions hence the reason they evacuated, but the 32-ft wave claim was nonsense. It was very obvious looking at the tsunami buoy data shortly after the EQ that no damaging tsunami had been generated.

Since the place is shaking like a chihuahua, the US should let it go cheap while they can still get rid of the place. :ok:

I do not have the dated records with me, but here in Japan it was several hours, perhaps half a day before we were given any clear indication that no tsunami was coming.

Either Kim's mining activities in his search for uranium/building a tunnel to invade the USA or it's that bloody UFO base again.

Russian subs cutting undersea cables again?

Subs cutting undersea cables ?
Imagine the mayhem that would cause , russian billionaire places big bets on nikkei and hangseng then bribes the right defence officials to make it happen, a nuclear sub on patrol deviates slightly and slides to a stop on the seabed near a large city of noodle slurpers and sends out a ROV that cuts a few fibre optic cables, not hard to find them as the locations of these things are Shown on electronic sea charts.
Cripple the internet and phone lines to a large city , say a business hub in asia ,then sit back and watch the stock markets go nuts.
No one would be any wiser and the finance guru’s on CNN would blame donald trump for it.
