The fascinating impressiveness of rigorous mathematical analysis, with its atmosphere of precision and elegance, should not blind us to the defects of the premises that condition the whole process.
Kelvin's defect of the premises was that he did not include heat due to radioactive decay. And in a bit of irony, it is this heat that causes convection within the earth, which causes seafloor spreading/plate tectonics. So Chamberlin got one thing right, and one thing wrong.
This brings back memories of the controversy with regard to Cringely (pen name) having a Ph.D. from Stanford. Some of us old-timers might remember that this is a topic of great discussion here.

BAH is not a third rate defense contractor. They provide software to three letter USA government agencies. If a contractor to three letter agencies is compromised, then this might affect the agencies especially if some future exploitable weakness has been discovered (and not later fixe). Or information about how the agencies is implementing security or other operational things.
Digital Pearl Harbor means many things, IMHO, but one is being surprised by an attack that you have not fully anticipated.
I also feel sorry for the poor fish in the barrel. What would be interesting to monitor is how far up the management chain the sh*t flies.
In a more perfect world, those that succumb to social engineering would then have their bosses/supervisors subjected to the same social engineering, and if they fail, their bosses/supervisors would then be subjected to social engineering....
The fundamental mode (0S2) for the Earth's resonance is about 54 minutes long. Higher mode free-oscillations have shorter periods. The key thing is that this mode, which can be excited by very large earthquakes (more energy released than a meteor impact), damps out after a few hours to a few days. Also note that the shorter the period of the oscillation, the faster the attenuation rate.
Teleseismic waves recorded to monitor the earth's seismicity have energy primarily in the 1 to 100 second period range (1 to 0.01 Hz). Higher frequencies are attenuated; attenuation is a function of wavelengths travelled. Lower frequencies/longer period waves require bigger earthquake source regions like those associated with tsunami generating events.
The HD sensors will need to be able to accurately monitor long period signals. I'm not sure they are capable of doing so, and secondly, the ambient noise around the computer would be a big problem.
Others have noted that not all earthquakes generate tsunamis. This is correct. For long-distance tsunamis that pose a risk, a magnitude 8 or greater earthquake is generally needed; there are about one earthquake of this size per year. Additionally, the location and characteristics of the earthquake (e.g., shallow focal depth, slow rupture speed) play a role whether a tsunami is generated.
Locally generated tsunamis can be triggered by smaller earthquakes (e.g., 1973 Kalapana event in Hawaii). Additionally, massive underwater landslides can also generate very big tsunamis (e.g., Storrega slide off of Norway).
There is already a global network of seismic stations that monitor earthquakes. First the event is detected, then a preliminary location is computed when enough stations have recorded the event. The magnitude and focal mechanism (seismic moment tensor) of the event can then be estimated based on this location and the characteristics of the seismic signals that have been recorded at the various seismic stations.
Those monitoring tsunamis base their initial assessment on these information. They can then more closely analyze the various seismic waveforms to better refine the preliminary information. If warranted, they then contact previously designated POC's to issue a tsunami alert (this was a problem for the 2004 tsunami, there were no designated POC's for the Pacific Tsunami Warning Center to contact).
How a P2P network could accomplish all of this remains to be seen.
On a side note, I used to play golf with the current head of the PTWC many, many years ago.
What he hated (and I provoked this) was I'm an American going to an American place in Canada. Unfortunately, to get from the airport to Argentia meant driving across New Foundland.
But the Canadian gods paid me back. It was snowing almost all the way to Argentia.
Your points are very good and ones that I usually follow when going into Canada. I did what you wrote except for my comment after being quizzed over and over again.
This guy didn't like that I was going to what was then American soil on Canadian land and that I told him so. My "mistake" was to remind him of this over and over again.
I don't blame him. I think he was trying to get me (by asking many redundant questions) to say what I was really going to be doing in Argentia. Why? Well you have to know what used to be at Argentia.
The only time I had problems with these types of questions was on a trip to Canada. It was on a trip to New Foundland while on official US Government business.
The Canadian Immigration officer was asking me a whole bunch of questions, is this a business trip? What type of business? What type of work again? Why are you on this trip? blah, blah, blah... I got a bit annoyed so I answered one question like this.
"I am going as an official government employee of the United States of America to the United States of America's Naval Base in Argentia to conduct United States of America business."
Woops! His expression on his face immediately changed, then he signal for someone to take me aside where they then emptied my bags and ask me more nice questions.
I guess he didn't like that the Brits turned over Argentia to the Yanks as part of the Lend Lease program during WWII. Or maybe I shouldn't have had that cocky smirk on my face when I gave my answer.
As a side note, I would like to point out the the US Marine Corps Reserves sponsors the Toys For Tots program. This is the biggest holiday charity in America.
Here's a nice article that was published on the 50th anniversary of this program.
The ice does not extend down for miles, and most of the Arctic Ocean can be traversed by submarines (except the continental shelf regions at times). The main pinch point is the relatively shallow Bering Strait if it is ice covered.
The Soviet sent their subs (i.e. their boomers like the Typhoon) under the ice because they were then more difficult to detect (acoustic environment terrible for surveillance), the transit from the USSR could be more easily hidden, and they could be poised to launch their ICBM's at a relatively short distance from the US. The US sent their subs into the Arctic to counter this threat.
IMHO, it is somewhat ironic. One of the first memorable commercial use of analog audio tape in America was to record Bing Crosby's radio show for ABC. Crosby didn't care too much for live performances on radio, so they recorded his show for later playback. The technology barely made it, but it proved to be a formula for later work.
BTW, I have several Ampex 1 inch tapes stored away in my office as well as a couple of Tascam cassette tape decks. The latter were the same models that were used by some folks at NPR over ten years ago. I know this because a NPR tech told me so.
This is what the real experts think about this. The topic of the mega-tsunami is at the end of the FAQ. So read it and learn something.
Note that one could point to a lot of active oceanic volcanoes and pose a similar threat level if one considers a tens of thousand of years time frame.
Another side note: When I was in grad school, I was the TA for one of the committee members.
True story. Two guys in my department dropped out of graduate school and joined the US Navy after seeing "Top Gun." One eventually became a pilot, while the other was rejected to flight school due to an old knee injury.
Usually, a movie, book, or a video game won't have an significant effect on someone, but sometimes they do. Ask John Hinckley (the guy that shot Reagan) what he thinks about Jodie Foster in the "Taxi Driver."
