I am sorry, I do not understand your question. Please clarify "subatomic".
If you actually meant subcritical, it is when they make a test device that is deliberately designed to never become critical. Such a device cannot produce a nuclear yield, but they can still make measurements on it (e.g. neutron flux peak, x-ray flux) helpful in designing functional nuclear weapons.
No, the tsunami did not trigger a nuclear blast. The nuclear blast at Fukushima Daiichi Nuclear Power Plant in Japan was caused by a loss of cooling functionality due to the earthquake which occurred before the tsunami.
Proton
Nuclear reactions
The subatomic particles that can change in a nuclear reaction are protons, neutrons, and electrons. During nuclear reactions, these particles can be gained or lost, leading to the formation of different elements and isotopes.
An underground nuclear blast is referred to as an underground nuclear test. It involves detonating a nuclear weapon below the surface of the Earth, effectively containing the explosion underground. This type of blast generates seismic waves that can be detected and analyzed for various purposes, including testing nuclear weapons technology.

The blast effects (which is all the question as worded asks about) would be the same as the blast effects of a weight of TNT identical to the nuclear bomb's yield (by definition). However a nuclear bomb has additional effects that the TNT doesn't, but as this question only asked about blast effects, I won't visit them.
yes, thousands
A nuclear blast can have devastating effects, including heat, blast pressure, and radiation that can result in immediate death. The impact of a nuclear blast depends on various factors, such as the distance from the explosion and the size of the bomb.
Blast, always blast.
Correct answer is blast effect
You think probable to neutrons.
