The damage that an underwater explosion inflicts on a submarine comes from a primary and a secondary shock wave. The primary shock wave is the initial shock wave of the depth charge, and will cause damage to personnel and equipment inside the submarine if detonated close enough.
The following lines are marked on the pool bottom - a line known as the shooting line is located 4 m (13 ft) from the face of the targets, a line known as the starting line is located 10 m (32 ft) from the shooting line and a line is located 3 m (10 ft) from the starting line to demarcate space for in-water preparation by competitors from the ...
Deep underwater explosions are those where the crater is small in comparison with the depth of the explosion, [2] or nonexistent. The overall effect of an underwater explosion depends on depth, the size and nature of the explosive charge, and the presence, composition and distance of reflecting surfaces such as the seabed, surface, thermoclines ...
Experts say Hamas’s tunnels could be a soldier’s nightmare and warn against sending any into the narrow passages, low on oxygen but full of twists and turns.

Tsunamis can occur when an underwater earthquake rapidly displaces massive amounts of water, leading to a large, long wave that builds in intensity as it crosses the ocean.
Plumes of ash filled the sky as the volcano rumbled to life for the first time in 19 years.
