why all the speculation
we have hard data on underwater nuclear detonation
from operation crossroads baker test
The Baker shot produced so many unusual phenomena
The underwater fireball took the form of a rapidly expanding hot "gas bubble" which pushed against the water, generating a supersonic hydraulic shock wave
When the gas bubble's diameter equaled the water depth, 180 feet (55 m), it hit the sea floor and the sea surface simultaneously. At the bottom, it started digging a shallow crater, ultimately 30 feet (9 m) deep and 2,000 feet (610 m) wide.[64] At the top, it pushed the water above it into a "spray dome," which burst through the surface like a geyser. Elapsed time since detonation was four milliseconds.[65]
As the bubble rose at 2,500 feet per second (762 m/s),[67] it stretched the spray dome into a hollow cylinder or chimney of spray called the "column," 6,000 feet (1,829 m) tall, 2,000 feet (610 m) wide, and with walls 300 feet (91 m) thick.
If they trigger a super volcano to erupt... how far will the outfall and tsunami reach?
Quoting: Anonymous Coward 10768732,500 feet per second (762 m/s),[67] it stretched the spray dome into a hollow cylinder or chimney of spray called the "column," 6,000 feet (1,829 m) tall, 2,000 feet (610 m) wide, and with walls 300 feet (91 m) thick.
with the compression of 70-100k pounds per square inch (at detonation site) one can only guesstimate the expansion rate of the fireball and its final size upon entry into the atmosphere as a 'very dirty' mix of sea floor and vaporized water
now as far the the super volcano is concerned, well
disrupting the equilibrium between the pressure under the crater cap and the pressure above (from sea mass) is NOT a good idea
at the instant of detonation the high pressure hydrolic shock wave would rapture the crater and shoot a column of pressurized water down the volcano permeating and loosening the bed rock
behind the shock wave comes a low pressure 'vacuum' that reverses the previous effects allowing the magma to escape through the volcanic tube ejecting the better part of the old crater
this secondary 'natural' gas/magma/etc bubble expands until reaching the surface whilst creating a tsunami the size of.........
the one in the ABYSS (directors cut only!!!) that freezes over manhattan created by the jellyfish type (magnetic field controlling) aliens
