Water vapor in the air condensed as a result of Prandtl–Meyer expansion fans decreasing the air pressure, density, and temperature below the dew point; making a spherical cloud that marked the location of the shock wave. Water filling the cavity formed by the bubble caused a hollow column of water, called the chimney or plume, to rise 6,000 ...
In a shock wave the properties of the fluid (density, pressure, temperature, flow velocity, Mach number) change almost instantaneously. [7] Measurements of the thickness of shock waves in air have resulted in values around 200 nm (about 10 −5 in), [8] which is on the same order of magnitude as the mean free path of gas molecules. In reference ...
Under the water, strange zombie-like men gather, walking from the wreck along the ocean floor to the island. As Dobbs gathers items to help prepare food, the zombies corner him in the water and one of them attacks; before it kills him, Dobbs falls in a cluster of sea urchins and is horribly mangled. Rose discovers his body while swimming.
A shock wave can be created when fluid is rapidly displaced by an explosive or projectile. Tissue behaves similarly enough to water that a sonic pressure wave can be created by a bullet impact, generating pressures in excess of 1,500 psi (10,000 kPa). [26]
A wide variety of volcanic processes can produce tsunamis. This includes volcanic earthquakes, caldera collapse, explosive submarine eruptions, the effects of pyroclastic flows and lahars on water, base surges with accompanying shock waves, lava avalanching into the sea, air waves from explosive subaerial eruptions, avalanches of cold rock, and avalanches of hot material.

“Nobody knows what it’s like to go under the water and let somebody help you out and bring you out. It’s a dream that you wish that you hadn’t had,” Pearl Davis, who also fell into the ...
Since heat does not leave the affected air mass, the change of pressure following a detonation is adiabatic, with an associated change of temperature.In humid air, the drop in temperature in the most rarefied portion of the shock wave can bring the air temperature below its dew point, at which moisture condenses to form a visible cloud of microscopic water droplets.
