An observation...
While it is an interesting computer animation of an underwater volcano - I did however noticed that the scenery in the first Twitter/X video above, is most likely from New Zealand, with view from the city of Auckland towards the Rangitoto volcano. So why is the twitter guy writing "HUNGA TONGA-HUNGA UNDERWATER VOLCANO ERUPTION 15th January 2022. Watch till the very end..." !?
That would only apply to the second (satellite) video.
Pozzuoli, Campi Flegrei Caldera, Napoli - Italy
2 Oct 2023
At German Vulkane.net, there have been numerous updates about the unsettled situation at Campi Flegrei Caldera volcano, and it's numerous, increasingly stronger earthquakes. So, here is the latest report:
Campi Flegrei: Und noch ein Erdbeben M 4,0 - Vulkane Net Newsblog
Gestern Abend bebte es um 20:06:26 UTC erneut unter dem süditalienischen Calderavulkan Campi Flegrei mit einer Magnitude 4,0.

Another earthquake in the range of 4 shakes Caldera volcano Campi Flegrei
Date 2 Oct 2023 | Time: 20:08:26 UTC | Location: 40.8302 ; 14.1495 | Depth: 2.6 km | Md 4.0
Yesterday evening, at 20:06:26 UTC, another earthquake struck beneath the Campi Flegrei caldera volcano in southern Italy. The earthquake had a magnitude of 4.0 and a hypocentre at a depth of 2.6 km. It was the second strongest earthquake since the beginning of the current uplift phase.
The epicentre was located slightly northeast of the Solfatara crater and not far from the Pisciarelli fumarole, which is considered particularly hot and active. Naturally, the moderate earth tremor had been felt by the residents of the caldera: The EMSC has perception reports within a radius of about 18 km around the epicentre. Accordingly, the quake attracted a lot of attention in the social media and, as always, people fear an imminent eruption of the volcano.
However, there are also voices to the contrary, saying that comparably strong earthquakes occurred shortly before the end of the ground uplift during the last uplift phases. Time will tell what happens next, no serious predictions can be made. What is striking, however, is the accumulation of moderate earthquakes with magnitudes of 3 or more, which are already relatively strong for the Caldera volcano. This is an indication that something is changing in the subsurface, and stronger earthquakes are normally associated with greater stresses in the subsurface.
Of course, the earthquake described did not come alone. It is part of a swarm of weaker earthquakes that had not completely subsided since the last stronger earthquake. According to seismological terminology, one should again distinguish between main earthquakes and aftershocks, but I think that all these earthquakes can safely be called swarm earthquakes.
The new weekly report of the INGV is expected today. As soon as it appears, there will be a small update with a summary of the events that were already exciting last week. In particular, it will be interesting to see whether there has been a change in the ground elevation, which is still reported at 15 mm per month.
Update: In the meantime, the weekly report has been published. In the observation period from 25 September to 1 October 2023, 270 earthquakes were localised. This is likely to be one of the highest weekly values.
The ground uplift is still 15 mm per month, but an acceleration of the uplift was detected, so that the actual value should be higher. The new value is to be determined only next week. The temperature of the Pisciarelli fumarole continues to be around 95 degrees. The fumarole's mud pool is largely dry and there is no condensate.

Underwater volcano / Japan

At German Vulkane.net an article was published about a small 60 cm Tsunami having been registered along the coast of Japan, which could have been induced by an earthquake sequence from a submarine volcano (while at the same time the author says that the earthquake itself is too weak to cause a tsunami...) Here article as follow:

Was a small tsunami triggered by submarine volcanic eruption?
Date 8 Oct 2023 | Time: 21:05:33 UTC | Location: 29.758°N 140.021°E | Depth: 10 km | Mb 5.3
Yesterday evening, a small tsunami reached the coast of the Japanese island of Honshu. The wave was about 60 cm high and caused minor property damage, mainly to boats that were pressed against quay walls. A tsunami alert was issued in Japan and the JMA informed about the event and wrote in a warning: "A tsunami is occurring and being in the sea or near the coast is dangerous. Anyone in the water should leave immediately and move away from the shore. As the current will continue to be strong, please avoid entering the sea or approaching the coast until the warning is lifted."
The possible cause was said to be an earthquake that occurred in the earthquake zone in the Izu-Bonin island arc area. The epicentre was said to have been near the volcanic island of Torishima and the hypocentre was described as lying flat. The magnitude was unknown at the time of the warning. The USGS now gives a magnitude of 5.3. The quake was part of a small swarm quake and occurred just over an hour before the tsunami hit Honshu.
But the quake was actually too weak to trigger a tsunami, unless it was accompanied by another submarine event. This could have been a large landslide or a submarine eruption. Both scenarios are conceivable because the earthquakes occurred in the area of the Sofu seamount, i.e. an underwater volcano with steep slopes. Of course, I favour the version of the submarine volcanic eruption as the trigger of the tsunami. This is also supported by the stronger earthquakes that have occurred more frequently since 2 October.
The events remind me of those that occurred in Mayotte in 2019. At that time, there was an earthquake sequence of strong earthquakes lasting several months, off the coast of the island near Madagascar. There were strong ground deformations on the island and later researchers found that earthquakes and deformation had been caused by a strong effusive volcanic eruption underwater.

It reminds me of a fever pitch.
Kind of like... unsettled feelings from within; reminding me of the accelerating events at the world stage today, especially since the Israeli-Gaza conflict, literally syphons human energy. I felt exhausted the first two days... and still feel the pull...
My theory is, that all that the fever-pitch human experience, has an influence on earth / through earth... ?
