    Yeah I've noticed that folks say that whan they don't understand what's being talked about.

    The further down you go, the stronger shock waves you get. My link explains exactly why that's so.

    Other effects

    The detonation of an explosive charge underwater results in an initial high-velocity shockwave through the water, in movement or displacement of the water itself and in the formation of a high-pressure bubble of high-temperature gas. This bubble expands rapidly until it either vents to the surface or until its internal pressure is exceeded by that of the water surrounding it. (The volumetric expansion of the bubble also leads to a drop in internal temperature in accordance with Charles’ Law.)

    At this point, as noted above, the overexpanded bubble collapses into itself, leading again to a rise in bubble pressure and internal temperature until such time as the bubble pressure exceeds water pressure. The bubble again expands, although to a rather smaller size. A second shockwave is produced by this expansion, although it will be less intense and of rather greater duration than the first. With each cycle, the bubble moves upwards until it eventually vents or dissipates into a mass of smaller bubbles.

    The number of cycles, while generally low, is difficult to predict; they and the overall effects, depend on explosion depth (and thus water pressure), the size and nature of the explosive charge and the presence, composition and distance of reflecting surfaces such as the seabed, surface, thermoclines, etc.

    This phenomenon has been extensively used in antiship warhead design since an underwater explosion (particularly one underneath a hull) can produce greater damage than an above-surface one of the same explosive size. Initial damage to a target will be caused by the first shockwave; this damage will be amplified by the subsequent physical movement of water and by the repeated secondary shockwaves or bubble pulse. Additionally, charge detonation away from the target can result in damage over a larger hull area.[4]

    NO, Actually is is about some people who omit part of what I said, when replying to my post. It is a mile down AND IT IS A SMALL YIELD. A small yield device that far down is NOT going to have the effect you are talking about.

    How could I leave out the warhead you would use if you haven't specified it?

    I already did. In fact, I mentioned small yield several times in this thread. It isn't my fault if you didn't read it before replying.

    Oh right, because "small yield" is an exact kilotonage AND the technical type of a specific nuclear device.

    Also, your posted calculations of how a depth of 5,000ft would amplify the blast, and your environmental impact statement were spot on.

    Pardon me Jerry - I go too far. But what the **** do you care if it is 10 Kilotons or 25 Kilotons?

    If you're going to take it to that level, then you need to know that I don't give a **** about this spill apart for its entertainment value.

    As for the thought experiment, the size of the warhead determines the size of the tsunami and earthquakes it will create.

    So I ask again...

    A depth aplifies the blast. The depth does not supress the blast, it makes the shock waves larger. Why? Because there's more stuff around the blast to move. This is how sound travels through the ground so well and we can hear countries on the other side of the plannet testing divices.

    So, how low is "low yeald"? Is your number large enough to seal the leak? How do you know?

    I knew I forgot something....like a smilie.

    As for your thought experiment, I did not think there were active faultlines in the area. Seems a small tsunami dealt at once may be preferably to a constant leak til August.

    By the way, nice display of empathy for the environmental damage.
